Service Procedure
SERVICE PROCEDURE^ 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) 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.
^ The serial number will display when the plus VI is recognized / connected.
4. Select Re/programming, Configuration.
5. Follow the C-III plus on-screen instructions and navigate to the screen shown in Figure 2.
IMPORTANT:
^ While navigating C-III plus, if the screen in Figure 1A displays, select Delete, and then Other Operation.
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 (above).
^ If there is a match, 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 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.
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 (step 11 below), 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.
ECM Recovery
Do not disconnect plus VI or shut down C-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 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 / 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:
^ 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: 70-105°C (158-221°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 (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. Close C-III plus.
17. Turn the ignition OFF.
BATTERY TESTING AND FINAL PROCESSES
1. Test the battery with the GR8 Multitasking Battery Diagnostic Station (battery tester).
^ If the battery passes testing, charge the battery if required by the battery tester.
^ If the battery does not pass testing, replace it with the one listed in PARTS INFORMATION.
> Make sure the replacement battery is fully charged and ready for service before releasing the vehicle to the customer.
> Reset / Re-initialize the Clock, Radio Presets, Power Windows, etc. (Refer to ADDITIONAL SERVICE WHEN REMOVING BATTERY NEGATIVE TERMINAL in the GI section of the ESM for details).
2. Test drive the vehicle. Make sure it operates correctly and the MIL is OFF.
^ If the MIL comes ON, refer to ASIST and / or the ESM for further diagnostic information.
^ Diagnosis and repairs beyond the ones described in the Repair Overview are not covered by this bulletin.
