1. CAUTIONS WHEN WORKING ON ELECTRICAL UNITSRemove the negative battery cable from the battery in advance when working on electrical units.

-

Make sure to turn "OFF" the ignition switch and other lamp switches before disconnecting or connecting the negative battery cable. (Otherwise, semiconductor parts can be damaged.)

If a fuse is blown, replace it with a rated capacity fuse. If you use a fuse with capacity higher than the specification, corresponding parts can be damaged or a fire can break out.

-Do not drop or apply excessive impact to sensors and relays.

FUSE AND RELAY

Make sure a connector is connected securely. Loose connection results in malfunction.

-

When disconnecting a connector equipped with a lock, press it down to the direction in the figure.

-

When checking voltage or continuity of the connector terminal with a circuit tester, insert the tester's probe from the harness side. For a seal type connector, the probe should be inserted through the hole in the rubber cap of the wiring. At this time, take care not to damage insulation of the wires and insert the probe until it contacts with the end of the connector terminal.

-

When inspecting the airbag system, make sure to use a diagnostic device, not a circuit tester.

2. CHECKING CABLES AND WIRESCheck for loose connection or rust.Check terminals and wires for corrosion due to electrolyte leakage.Check terminals and wires for open circuit.Check wire insulation and coat for damage, crack or deformation.Check that conducting parts of the terminals do not contact with other metal parts, such as vehicle body or other parts.Check that the grounding part has continuity with mounting bolts and vehicle body.Check that wires are properly routed.Make sure that wires are securely fixed to avoid contact with sharp body parts and high-temperature parts, such as the exhaust manifold and exhaust pipes.The rotating parts, such as fan pulley and fan belt, perturbative parts and wiring should be secured tightly at regular intervals.Wiring between fixed parts, such as the vehicle body, and vibrating parts, such as the engine, should be fixed after making it slack to afford vibration.

4) Operating Process by Power Supply

(1) Rear wiper relay

(2) Rear fog lamp relay

Power supply: SB4, No. 39, ICM B6When turning ON/OFF the wiper switch with IGN2 ON, the rear wiper motor relay is turned ON/OFF.

When pressing the rear fog lamp switch with IGN2 ON (headlamp ON condition), the rear fog lamps are turned ON. When pressing the rear fog lamp switch again during the operation, the rear fog lamps are turned OFF.The rear fog lamps do not come ON when the engine is not running or the light switch is OFF. The rear fog lamps should not automatically come on again if they have been turned OFF by any other way other than the switch.
