Introduction

Flash reprogramming allows the ECU software to be updated without replacing the ECU. Flash calibration updates for specific vehicle models/ECUs are released as field-fix procedures described in individual Service Bulletins. This bulletin details the Techstream ECU flash reprogramming process and outlines use of the Technical Information System (TIS) and the Calibration Update Wizard (CUW). Flash calibration updates can only be applied to the vehicle/ECU combination for which they are intended. ECUs have internal security that will not allow them to be programmed with another ECU's information.

ECU

Electronic Control Unit (ECU) is a Lexus term used to describe integrated computerized devices responsible for managing the operation of a system or subsystem . For the purposes of this bulletin , the term " ECU" is used as a generic label for the following SAE J1930 standard references:

• Powe rtrain Control Module (PCM)

• Engine Control Module (ECM)

• Transmission Control Module (TCM)

• Or any other Lexus spec ific control unit

Techstream Preparatio n

Selecting the Correct VIM.

Techstream software requires a VIM selection before it can be used for reprogramming.

Perform the fol lowing :

1. Select Setup from the Techstream Main Menu screen.

2. Select VIM Select from the Setup drop down menu. Figure 1.

Techstream Preparation (Continued)

3. Select the correct Interface Setup from the drop down list.

• If using Techstream 2.0, select MongoosePro MFC.

• If using Techstream Lite, select Mongoose MFC or MongoosePro MFC (depending on the cable being used).

NOTE

Mongoose Driver MUST be installed before Mongoose select ions will be available.

See TIS - Diagnostics - Scantoo/ page for addit ional informat ion.

• If using TIS Techstream, select TIS Techstream VIM.

4. Click OK.

Process Overview

Techstream ECU flash reprogramming is a 4-step process:

1. Verify the vehicle's applicability for recalibration and locate desired calibration file by performing the Techstream Health Check function.

NOTE

Techstream will automatically search TIS for the appropriate Serv ice Bullet in using the current Calibratio n ID from the vehicle. Calibratio n fi le links can be found embedded in the corresponding Service Bulletin.

2. Connect the GR8 Battery Diagnostic Station using "Power Supply Mode" only.

The GR8 Battery Diagnostic Station includes a Power Supply Mode to help maintain battery voltage at 13.5 volts during ECU reprogramming.

NOTICE

ECU damage may occur if the correct battery charger mode setting is NOT used.

3. Locate appropriate calibration ID and reprogram the vehicle ECU with Techstream.

Techstream uses the Calibration Update Wizard (CUW) application to open calibration fi les and facilitate the ECU flash reprogramming process.

4. Attach the Authorized Vehicle Modification Label.

Modifications to ECU calibrations MUST be recorded and properly displayed on the vehicle using the Authorized Modification Label.

NOTICE

Errors during the flash reprogramming process can permanently damage the vehicle ECU. Minimize the risk by following the steps below.

• Battery voltage MUST NOT FALL BELOW 11 .4 volts during reprogramming . Confirm battery voltage is higher than 11.4 volts, but be sure voltage DOES NOT RISE ABOVE 16.0 vo lts during reprogramming.

• Turn OFF all vehic le accessories (e.g. aud io system, A/C, interior lights, DRL, etc.). Do NOT add to or significantly change the vehicle's electrical load while reprog ramming.

• Confirm the hood is open and ensure under hood temperature does NOT exceed 158°F (70°C).

• Confirm cable connections between the vehicle and Techstream are secure.

• Do NOT disconnect or turn off Techstream or vehicle ignition during reprogramming.

• Set parking brake.

• Complete ALL flash ca libration updates provided for each ECU.

• If the battery's state of charg e or capacity are in question, test with SST. No. 00002-V8150-KIT " Digital Battery Analyzer," and follow Service Bulletin No. PG001-06, " Battery Maintenance for In-Stock Vehicles & Pre-Delivery" , or the appropriate " Maintenance for HV & Aux iliary Batteries" Service Bulletin.

• The GR8 Battery Diagnostic Station MUST be used in Power Supply Mode to maintain battery voltage at 13.5 volts while flash reprogramming t he vehicle. For details on how to use the GR8 Battery Diagnostic Station, refer to the GR8 Instruction Manual located on TIS, Diagnostics - Tools & Equipment - Battery Diagnostics.
