Service Procedure
NOTE:^ 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, refer to "CONSULT-III plus (C-III plus) ECM or TCM 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 (ECM reprogram only), you will be required to perform Throttle Valve Closed Position, Idle Air Volume Learn, Accelerator Closed Position, and DTC erase.
CAUTION
NOTE:
^ The following procedure is for reference only and some of the system screens may not match exactly.
^ The following steps will be used twice. First to reprogram the TCM and then the ECM.
CAUTION:
There are two different possible ECM reprograms based on which generation of transmission is in the vehicle. TCM must be reprogrammed first.
TCM reprogramming:
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.
^ The 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 either the TRANSMISSION or ENGINE reprogramming screens (ENGINE screen Shown in Figure 2) above.
6. When you get to the screen shown in Figure 2 (TRANSMISSION or ENGINE), confirm this bulletin applies as follows.
B. Find the TCM or ECM Part Numbers and write it on the repair order.
NOTE:
This is the current TCM or ECM Part Number (P/N).
C. Compare the P/Ns you wrote down to the numbers in the Current TCM Part Number column in Table A above.
^ If there is a match with either TCM or ECM, this bulletin applies. Continue with the reprogramming procedure.
^ If there is not a match, this bulletin does not apply. Close C-III plus and refer to ASIST for further diagnostic information.
7. Follow the on-screen instructions to navigate C-III plus to reprogram the TCM first (and then the ECM).
^ When programming the ECM the file number written down in step 13 will be displayed in Figure 3 under "Other Information".
^ Select the file number that was written down in step 13, and then follow the on-screen instructions.
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 refer back to ASIST for further diagnosis.
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 under "ECM/TCM recovery".
9. Disconnect the battery charger from the vehicle.
10. Select Next.
11. When the entire reprogramming process is complete (TRANSMISSION or ENGINE), the screen in Figure 5 will display.
12. Verify the before and after part numbers are different.
> When reprogramming the ECM (after TCM reprogramming is complete), verify the before and after part numbers and then skip to step 14.
13. After TCM reprogramming is complete:
a. Compare the "Part number after Reprogramming" to the numbers in Table B above.
b. Choose the correct ECM file to use from Table B, and write it down.
> Figure 6 is shown as a reference only and will be displayed instead of the screen in Figure 3 during the ECM reprogramming procedure.
14. Print a copy of this screen (Figure 5) and attach it to the repair order for warranty documentation.
15. Select Confirm.
ECM reprogramming (after TCM reprogramming has been completed):
> Select Home then perform steps 4 - 12 and then 14 - 20 to reprogram ECM.
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 7 and information.
^ If reprogramming does not complete and the "X" icon displays as shown in Figure 8 and information.
NOTE:
^ These operations are required before C-III plus will provide the final reprogramming confirmation report.
16. Follow the on-screen instructions to perform the following:
^ Throttle Valve Closed Position
^ Idle Air Volume Learn (IAVL)
NOTE:
^ Listed below are common conditions required for IAVL to complete.
^ If IAVL does not complete within a few minutes, a condition may be out of range.
^ Refer to the appropriate Electronic Service Manual (ESM) for specific conditions required for the vehicle you are working on.
> 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
^ Accelerator Pedal Close Position Learning
^ Erase DTCs
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 reprogramming are not covered by this bulletin.
