11 0000779

CONNECTOR CONTINUITY AND VOLTAGE TEST Follow the steps below to avoid causing poor connector contact and/or reduced waterproof performance of waterproof connectors when checking continuity and/or voltage at connectors. (1) If checking is performed with the circuit in the state of

continuity, be sure to use the special tool (harness connector). Never insert a test bar from the harness side, because to do so will reduce the waterproof performance and result in corrosion.

(2) If the connectors are disconnected to check the female pin, use the harness intended for checking the contact pressure of the connector pin. Never force the insertion of a test bar, because to do so will cause poor or improper contact.

(3) When checking the male pin, contact the test bar directly to the pins. Care must be taken not to short-circuit the connector pins.

TERMINAL ENGAGEMENT CHECK When the terminal stopper of connector is out of order, engagement of male and female terminals becomes improper even when the connector itself is engaged perfectly and the terminal sometimes slips out to the rear side of connector. Ascertain, therefore, that each terminal does not come off the connector by pulling each harness wire.

CONNECTOR TERMINAL ENGAGEMENT AND DISENGAGEMENT Connectors which are loose shall be rectified by removing the female terminal from connector housing and raising its lance to establish a more secure engagement. Removal of connector terminal used for MFI and 4 A/T control circuit shall be done in the following manner.

COMPUTER CONNECTOR (1) Insert screwdriver [1.4 mm (.06 in.) width] as shown in

the figure, disengage front holder and remove it.

GENERAL - How to Diagnose 29

HOW TO DIAGNOSE 110000780

The most important point in troubleshooting is to determine “Probable Causes”. Once the probable causes are determined, parts to be checked can be limited to those associated with such probable causes. Therefore, unnecessary checks can be eliminated. The determination of the probable causes must be based on a theory and be supported by facts and must not be based on intuition only.

TROUBLESHOOTING STEPS If an attempt is made to solve a problem without going through correct steps for troubleshooting, the problem symptoms could become more complicated, resulting in failure to determine the causes correctly and making incorrect repairs. The four steps below should be followed in troubleshooting.

Observation of Problem Symptoms

I Determination of Probable Causes

0

Confirmation

Observe the symptom carefully. Check if there are also other problems.

In determining the probable causes, it is necessary to check the wiring diagram to understand the circuit as a system. Knowl- edge of switches, relays and other parts is necessary for accu- rate determination. The causes of similar problems in the past must be taken into account.

Troubleshooting is carried out by making step by step checks until the true cause is found. Always go through the procedures considering what check is to be made where for the best results.

After the problems are corrected, be sure to check that the system operates correctly. Also, check that new problems have not been caused by the repair.

~

INFORMATION FOR DIAGNOSIS This manual contains the cable diagrams as well as the individual circuit drawings, operational explanations, and troubleshooting hints for each component required to facilitate the task of troubleshooting. The information is compiled in the following manner: (1) Cable diagrams show the connector positions, etc., on the actual vehicle as well as the harness path. (2) Circuit drawings show the configuration of the circuit with all switches in their normal positions. (3) Operational explanations include circuit drawings of voltage flow when the switch is operated and

how the component operates in reaction. (4) Troubleshooting hints include numerous examples of problems which might occur, traced backward

in a common-sense manner to the origin of the trouble. Problems whose origins may not be found in this manner are pursued through the various system circuits. NOTE Components of MFI, ETACS, ECS, etc. with electronic control unit do not include 3 and 4 above. For this information, refer to a manual which includes details of these components.

INSPECTION 110W0781

1. Visual and aural checks Check relay operation, blower motor rotation, light illumination, etc. visually or aurally. The flow of current is invisible but can be checked by the operation of the parts.

2. Simple checks For example, if a headlight does not come on and a faulty fuse or poor grounding is suspected, replace the fuse with a new one or ground the light to the body by a jumper wire to determine which part is responsible forthe problem.

3. Checking with instruments Use an appropriate instrument in an adequate range and read the indication correctly. You must have sufficient knowledge and experience to handle instruments correctly.

INSPECTION INSTRUMENTS 110000782

In inspection, make use of the following instruments. 1. Test lights

A test light consists of a 12V bulb and lead wires. It is used to check voltages or short-circuits.

2. Self-power test light A self-power test light consists of a bulb, battery and lead wires connected in series. It is used to check continuity or grounding.

4. Voltmeter Avoltmeter is used to measure the circuit voltage. Normally, the positive (red lead) probe is applied to the point of voltage measurement and the negative (black lead) probe to the body ground.

5. Ohmmeter An ohmmeter is used to check continuity or measure resistance of a switch or coil. If the measuring range has been changed, the zero point must be adjusted before measurement.

CHECKING SWITCHES 110000783

In a circuit diagram, a switch IS represented by a symbol and in the idle state. 1. Normal open or normal close switch

Switches are classified into those which make the circuit open and those which make the circuit closed when off.

2. SWITCH CONNECTION This figure illustrates a complex switch. The continuity between terminals at each position is as indicated in the table below.

Position I Terminal No.

CHECKING RELAYS 11 0000784

1. When current flows through the coil of a relay, its core is magnetized to attract the iron piece, closing (ON) the contact at the tip of the iron piece. When the coil current is turned off, the iron piece is made to return to its original position by a spring, opening the contact (OFF).

2. By using a relay, a heavy current can be turned on and off by a switch of small capacity. For example, in the circuit shown here, when the switch is turned on (closed), current flows to the coil of the relay. Then, its contact is turned on (closed) and the light comes on. The current flowing at this time to the switch is the relay coil current only and is very small.

3. The relays may be classified into the normal open type and the normal close type by their contact construction. NOTE The deenergized state means that no current is flowing through the coil and the energized state means that current is flowing through the coil.

21680237

When a normal close type relay as illustrated here is checked, there should be continuity between terminals (1) and (2) and between terminals 3 and 4 when the relay is deenergized, and the continuity should be lost between terminals 3 and 4 when the battery voltage is applied to the terminals 1 and 2. A relay can be checked in this manner and it cannot be determined if a relay is okay or faulty by checking its state only when it is deenergized (or energized).

CHECKING FUSES 110000785

A blade type fuse has test taps provided to allow checking of the fuse itself without removing it from the fuse block. The fuse is okay if the test light comes on when its one lead is connected to the test taps (one at a time) and the other lead is grounded. (Change the ignition switch position adequately so that the fuse circuit becomes live.)

CAUTIONS IN EVENT OF BLOWN FUSE When afuse is blown, there are two probable causes as follows: One is that it is blown due to flow of current exceeding its rating . The other is that it is blown due to repeated on/off current flowing through it. Which of the two causes is responsible can be easily determined by visual check as described below.

(1) Fuse blown due to current exceeding rating The illustration shows the state of a fuse blown due to this cause. In this case, do not replace the fuse with a new one hastily since a current heavy enough to blow the fuse has flowed through it. First, check the circuit for shorting and check for abnormal electric parts. Only after the correction of such shorting or parts, fuse of the same capacity should be used as a replacement. Never use a fuse of larger capacity than the one that has blown. If such a fuse is used, electric parts or wirings could be damaged before the fuse blows in the event an overcurrent occurs again.

State of fuse blown due, to thermal fatigue (2) Fuse blown due to repeated current on/off The illustration shows the state of a fuse blown due to repeated current on/off. Normally, this type of problem occurs after fairly long period of use and hence is less frequent than the above type. In this case, you may simply replace with a new fuse of the same capacity.

CHECKING CABLES AND WIRES 11 0000786

1. Check connections for looseness, rust and stains. 2. Check terminals and wires for corrosion by battery electro-

lyte, etc. 3. Check terminals and wires for open circuit or impending

open circuit. 4. Check wire insulation and coating for damage, cracks

and degrading. 5. Check conductive parts of terminals for contact with other

metallic parts (vehicle body and other parts). 6. Check grounding parts to verify that there is complete

continuity between attaching bolt(s) and vehicle body. 7. Check for incorrect wiring. 8. Check that wirings are so clamped as to prevent contact

with sharp corners of the vehicle body, etc. or hot parts (exhaust manifold, pipe, etc.).

9. Check that wirings are clamped firmly to secure enough clearance from the fan pulley, fan belt and other rotating or moving parts.

10. Check that the wirings between the fixed parts such as the vehicle body and the vibrating parts such as the engine are made with adequate allowance for vibrations.

BATTERY HANDLING 110003532

When checking or servicing does not require power from the vehicle battery, be sure to disconnect the cable from the battery (-) terminal. This is to prevent problems that could be caused by a short circuit. Disconnect the (-) terminal first and reconnect it last.

Caution 1. Before connecting or disconnecting the negative

cable, be sure to turn off the ignition switch and the lighting switch. (If this is not done, there is the possibil- ity of semiconductor parts being damaged.)

2. After completion of the work steps [when the battery’s negative (-)terminal is connected], warm up the engine and allow it to idle for approximately ten minutes under the conditions described below, in order to stabilize the engine control conditions, and then check to be sure that the idling is satisfactory. Engine coolant temperature: 85-95°C (1 85-203°F) Lights, electric fans, accessories: OFF Transaxle: Neutral position ( A / l models: ‘“”or “P”) Steering wheel: Neutral (center) position

GENERAL ELECTRICAL SYSTEM CHECKS

A circuit consists of the power supply, switch, relay, load, ground, etc. There are various methods to check a circuit including an overall check, voltage check, short-circuit check and continuity check. Each of these methods is briefly described in the following. 1. VOLTAGE CHECK

110000788

(1) Ground one lead wire of the test light. If a voltmeter is used instead of the test light, ground the grounding side lead wire.

(2) Connect the other lead wire of the test light to the power side terminal of the switch connector. The test light should come on or the voltmeter should indicate a voltage.

(3) Then, connect the test light or voltmeter to the motor connector. The test light should not come on, or the voltmeter should indicate no voltage. When the switch is turned on in this state, the test light should come on, or the voltmeter should indicate a voltage, with motor starting to run.

(4) The circuit illustrated here is normal but if there is any problem such as the motor failing to run, check voltages beginning at the connector nearest to the motor until the faulty part is identified.


2. SHORT-CIRCUITS CHECK Because the fuse has blown, it is probable that there is a short-circuited circuit. Follow the procedures below to narrow down the short-circuit location.

Take out the blown fuse and connect the test light to the disconnected terminal (switch OFF)

3. CONTINUITY CHECK (1) When the switch is in the OFF position, the self power

test light should come on or the ohmmeter should read 0 ohm only when the terminals 1 and 2 are inter- connected.

(2) When the switch is the ON position, the self power test light should come on or the ohmmeter should read 0 ohm only when the terminals 3 and 4 are inter- connected.

When auto compressor control unit outputs LO signal (0 V)

When the engine coolant temperature reaches 85°C (185”F), the thermo switch of radiator is activated. This energizes the radiator fan motor relay and condenser fan motor relay causing the radiator fan and condenser fan to rotate at high speed. When auto compressor control unit outputs HI signal (Battery positive voltage)

The fan motor control relay is turned on by the power from the auto compressor control unit, and this is transmitted through the resistor to nonconditionally run the condenser fan and radiator fan at low speed. At high temperatures in summer, etc, when the refrigerant line pressure on the medium-pressure side becomes high to turn on the triple pressure switch (medium-pressure) or the temperature of the engine coolant rises to 85°C (185°F) and the thermo switch IS turned on, the condenser fan motor relay becomes also turned on. As the result, the condenser fan runs also turned on. As the result, the condenser fan runs also at high speed together with the radiator fan.

Engine coolant tern- perature sensor "C (OF)

4 . 8 L Engine (From 1994 Models)> OPERATION 0 The engine control module controls the power

transistors (high speed and low speed) in the module to provide radiator fan motor and condenser fan motor rotation controls in accor- dance with the engine coolant temperature and vehicle speed. When the engine control module turns on the power transistor in the module, the current flows to the engine control module through the fan motor relay coil. If the current flows to the fan motor relay coil, the switch of the relay turns on to supply the motor driving power. This will cause the current to flow from the battery to the radiator fan motor and the condenser fan motor through the re- spective relay switches. When both air conditioning switch and refrigerant medium pressure switch are ON, the radiator fan motor and the condenser fan motor rotate at high speeds regardless of the vehicle speed and the engine coolant temperature.

POWER WINDOWS <4-DOOR MODELS ONLY> OPERATION 110003584 TROUBLESHOOTING HINTS

When the power window (main or sub) switch is depressed (UP or DOWN) with the ignition switch in the ON position, current flows through fusible link No. 7 to the power window motor. This energizes the power window motor causing the door window glass to open or close. When the DOWN side of the power window main switch (driver's seat side switch) is depressed all the way, it is locked in the depressed position and the power window motor is operated until the door glass is fully opened. When the power window lock switch is placed in the LOCK (OFF) position, operating a switch other than the ones for the driver's side window (main) does not cause the power window motor to be operated. The power window motor is provided with a circuit breaker that protects the motor from damage caused by overcurrent. Reference: Circuit breaker characteristics Restricts the motor at room temperature [20 to 25°C (68 to 77"F)I; Opens following 4-to-40-sec. initial energization time; Resets with 60 seconds if left open thereafter.

HEATER OPERATION 110003590

0 When the ignition switch is turned ON, the blower relay is energized. If the blower switch is turned ON (LO, ML, MH, or HI position) in this condition, the blower is activated through the circuit via resistor at a speed corresponding to the blower switch position.

I b

COMPONENT LOCATION

TROUBLESHOOTING HINTS 1. Blower motor is energized at one switch position

and not energized at another. 0 Check harness and connectors between

defective switch position and resistor (or blower motor in HI position).

2. Blower motor is energized only when switch is positioned in HI.

Check resistor. 3. Blower motor speed does not represent the

switch position. 0 Check blower switch.

The refrigerant temperature switch, which senses the temperature of the refrigerant, is deactivated with temperature 155°C (311 O F ) or higher. When the air conditioning switch is set to the "DRY" mode, the air thermo sensor detects the temperature of the air emitted from the evapora- tor; the A/C compressor clutch relay is switched OFF if the temperature is 2.2"C (36°F) or lower. Furthermore, when the air conditioning switch is set to the "ECONO mode, the N C compressor clutch relay is switched off at temperatures of 7°C (45°F) or below. The engine coolant temperature sensor senses the temperature of engine coolant, and it is turned off at 115°C (239°F) or higher temperatures. The triple pressure switch turns OFF when the refrigerant pressure becomes excessively high or low, thus protecting the compressor circuit. (See Table below.)

OPERATION 110003603

<Low-speed (and high-speed) wiper operation> 0 When the wiper switch is placed in the LO posi-

tion with the ignition switch in the ACC or ON position, wipers operate continuously at low speed.

0 Placing the wiper switch in the HI position causes the wipers to operate at high speed.

<Auto wiper stop operation> 0 When the wiper switch is placed in the OFF

position, the cam contacts of wiper motor causes current to flow through the auto wiper stop circuit, allowing the wiper blades to cycle before they reach to the stop positions.

When the wiper switch is placed in the INT position with the ignition switch in ACC or ON position, the intermittent wiper relay is energized causing the intermittent wiper relay contacts to close and open repeatedly. When the contacts are closed, the wiper motor is energized. When the wiper motor is energized, the relay contacts open; however, the cam contacts keep the wiper motor energized until the wiper blades return to their stop position.

When the washer switch is turned ON, the intermittent wiper relay contacts close causing wipers to cycle two to three times.

The washer-wiper operates in the priority even during intermittent operation of the wiper.

OPERATION 11 OW361 4

el993 models> Automatic Seat Belt Warning Light This warning light warns the driver and front passenger to fasten their seat belts. If one or more seat belts are not fastened, the automatic seat belt control unit detects that fact and causes the warning light to be illuminated or flash. How long the light is illuminated or how many times it flashes depends on whether only one, or both of the belts remain unfastened. Automatic Seat Belt Warning Buzzer This warning buzzer also warns the driver and front passenger to fasten their seat belts as the warning light does. It sounds continuously or intermittently, depending on how the belts remain unfastened.

4 994 models> Automatic Seat Belt The shoulder belt moves automatically to the set (fasten) position when the front passenger door is closed and the ignition key is turned to the “ON” position. When the front passenger door is opened, the shoulder belt automatically moves to the OFF (unfastened) position. Automatic Seat Belt Warning Light 0 Illuminates for 6 seconds as soon as the ignition

switch is placed in “ON” position. 0 Blinks when the “Fasten” switch is turned on

while the ignition switch is placed in “ON” position and the front passenger door is closed. Illuminates for approx. 1 minute when the ignition switch is turned from “OFF to “ON” position with the outer switch turned off.

When the front passenger door is opened and the sliding anchor begins to move to release the shoulder belt, the buzzer sounds for about 1 second. When the ignition switch is turned from “OFF” to “ON” position with the driver seat buckle switch OFF, the buzzer sounds intermittently for approx. 6 seconds.
