^ If you are not familiar with the reprogramming procedure, click here. This will link you to the "CONSULT- III plus (C-III plus) Reprogramming" general procedure.
Preparation for Reprogramming
^ Take the vehicle for a 10 minute drive in order to meet the following Idle Air Volume Learn (IAVL) conditions:
> Engine coolant temperature: 70 -100°C (158 -212°F)
> Battery voltage: More than 12.9V (At idle)
> Transmission: Warmed up
NOTE:
^ After ECM reprogramming is complete, you will be required to perform Throttle Valve Closed Position, Idle Air Volume Learn (IAVL), and Accelerator Closed Position.
^ The above conditions are required for the IAVL to complete.
CAUTION
1. Connect the CONSULT PC to the vehicle to begin the reprogramming procedure.
2. Start C-III plus.
3. Wait for the plus VI to be recognized.
^ Serial number will display when the plus VI is recognized.
4. Select Re/programming, Configuration.
5. Follow the C-III plus on-screen instructions and navigate to the screen shown in Figure 2.
6. When you get to the screen shown in Figure 2, confirm this bulletin applies as follows:
A. Find the ECM Part Number and write it on the repair order.
B. Compare the P/N you wrote down to the numbers in the Current ECM Part Number column in Table A.
^ If there is a match, this bulletin applies. Continue with the reprogramming procedure.
^ If there is not a match, this bulletin does not apply. Return to ASIST for further diagnostic and repair information.
7. Follow the on-screen instructions to navigate C-III plus and reprogram the ECM.
