Service Procedure
^ This procedure will require reprogramming of the ECM first, and for some vehicles the 1CM second, which means most steps in this procedure may need to be done twice.^ Most instructions for reprogramming with CONSULT-III plus (C-III plus) are displayed on the CONSULT PC screen.
^ If you are not familiar with the reprogramming procedure, visit 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. Open ASIST on the CONSULT PC and start C-III plus.
3. Wait for the plus VI to be recognized / connected.
^ Serial number will display when the plus VI is recognized / connected.
4. Select Re/programming, Configuration.
5. Follow the on-screen instructions and navigate C-III plus to the screen shown in Figure 2 on the next page.
6. When you get to the screen shown in Figure 2, confirm this bulletin applies as follows:
A. Find the ECM or TCM Part Number and write it on the repair order.
B. Compare the P/N you wrote down to the numbers in the Current ECM (or TCM) Part Number column in Table A (or Table B).
^ If there is a match, this bulletin applies. Continue with the reprogramming procedure.
^ If there is not a match, reprogramming does not apply. Make sure to check both ECM and TCM for a match.
Table A (ECM)
Table B (TCM)
7. Follow the on-screen instructions to navigate C-III plus and reprogram the ECM (and TCM, if it applies).
8. When the screen in Figure 4 displays, reprogramming is complete.
NOTE:
If the screen in Figure 4 does not display (reprogramming does not complete), refer to ECM/TCM Recovery.
9. Disconnect the battery charger from the vehicle.
10. Select Next.
ECM/TCM recovery:
Do not disconnect plus VI or shut down Consult III plus if reprogramming does not complete.
If reprogramming does not complete and the "!?" icon displays as shown in Figure 5:
^ Check battery voltage
(12.0-15.5 V).
^ Ignition is ON, engine OFF.
^ External Bluetooth(R) devices are OFF.
^ All electrical loads are OFF.
^ Select retry and follow the on screen instructions.
^ "Retry" may not go through on first attempt and can be selected more than once.
If reprogramming does not complete and the "X" icon displays as shown in Figure 6:
^ Check battery voltage
(12.0 - 15.5 V).
^ CONSULT A/C adapter is plugged in.
^ Ignition is ON, engine OFF.
^ Transmission is in Park.
^ All C-III plus / plus VI cables are securely connected.
^ All C-III plus updates are installed.
^ Select Home, and restart the reprogram procedure from the beginning.
11. Follow the on-screen instructions to perform the following:
NOTE:
For TCM reprogramming, only erase DTCs as needed.
^ Throttle Valve Closed Position.
^ Idle Air Volume Learn (IAVL).
NOTE:
^ Listed below are the conditions required for IAVL to complete.
^ If IAVL does not complete within a few minutes, a condition may be out of range.
> Engine coolant temperature: 70 - 100° C (158 - 212°F). Battery voltage: More than 12.9V (At idle).
> Selector lever: P or N.
> Electric load switch: OFF (Air conditioner, headlamp, and rear window defogger).
> Steering wheel: Neutral (Straight-ahead position). Vehicle speed: Stopped.
> Transmission: Warmed up (ATF TEMP SE less than 0.9V).
^ Accelerator Pedal Close Position Learning.
^ Erase DTCs.
12. When the entire reprogramming process is complete, the screen in Figure 7 will display.
13. Verify the before and after part numbers are different.
14. Print a copy of this screen (Figure 7) and attach it to the repair order for warranty documentation.
15. Select Confirm.
16. Make sure you have performed ECM (and if applicable TCM) reprogramming (ECM first).
17. Close C-III plus.
18. Turn the ignition OFF.
19. Disconnect the plus VI from the vehicle.
20. Test drive the vehicle and make sure it operates correctly and the MIL is OFF.
^ If the MIL comes ON, go back to ASIST for further diagnostic information.
^ Diagnosis and repairs beyond ECM or TCM reprogramming are not covered by this campaign bulletin.
