ECM Reprogram
NOTE:^ Most instructions for reprogramming with CONSULT-III plus (C-Ill plus) are displayed on the CONSULT PC screen.
^ 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.
^ 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
^ After reprogramming is complete, you will be required to perform Throttle Valve Closed Position, Idle Air Volume Learn, Accelerator Closed Position, and DTC erase.
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 the C-III plus 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.
NOTE:
This is the current ECM Part Number (P/N).
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, continue with the reprogramming procedure.
^ If there is not a match, reprogramming is not needed. Close C-III plus and disconnect from the vehicle.
7. Follow the on-screen instructions to navigate C-III plus and reprogram the ECM.
NOTE:
^ In some cases, more than one new P/N for reprogramming is available.
> In this case, the screen in Figure 3 displays.
> Select and use the reprogramming option that does not have the message "Caution! Use ONLY with NTBXX-XXX".
^ If you get this screen and it is blank (no reprogramming listed), it means there is no reprogramming available for this vehicle. Close C-III plus and disconnect from the vehicle.
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 the information below.
9. Disconnect the battery charger from the vehicle.
10. Select Next.
NOTE:
^ In the next steps, you will perform Throttle Valve Closed Position, Idle Air Volume Learn, Accelerator Closed Position, and DTC erase.
^ These operations are required before C-III plus will provide the final reprogramming confirmation report.
If reprogramming does not complete and the"!?" symbol displays as shown in Figure 5:
^ Check battery voltage (12.0 - 15.5V).
^ Ignition is ON, Ready Mode is OFF.
^ External Bluetooth(R) devices are OFF.
^ All electrical loads are OFF.
^ Select Retry and follow the on screen instructions.
NOTE:
Retry may not go through on first attempt and can be selected more than once.
If reprogramming does not complete and the "X" symbol displays as shown in Figure 6:
^ Check battery voltage (12.0 - 15.5V).
^ CONSULT A/C adapter is plugged in.
^ Ignition is ON, Ready Mode is OFF.
^ Transmission in Park.
^ All C-III plus / plus VI cables are securely connected.
^ All C-III plus updates are installed.
^ Select Home, and then restart the reprogram procedure from the beginning.
11. Follow the on-screen instructions to perform the following:
^ 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, rear window defogger)
> Steering wheel: Neutral (Straight-ahead position)
> Vehicle speed: Stopped
> Transmission: Warmed up (for CVI - ATF TEMP SEN 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. Close C-III plus.
17. Turn the ignition OFF.
18. Disconnect the plus VI from the vehicle.
19. Test drive the vehicle and make sure it operates correctly and the MIL is OFF.
^ If the MIL comes ON, go to ASIST for further diagnostic information.
