ECM Reprogram
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, 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:

¾ Engine coolant temperature: 70 -100°C
(158 - 212°F)
¾ Battery voltage: More than 12.9V (At idle)
¾ Transmission: Warmed up
Figure A
•

After reprogramming is complete, you will be required to perform Throttle Valve
Closed Position, Idle Air Volume Learn, Accelerator Closed Position, and DTC
erase.

CAUTION:
•

Connect a battery charger to the vehicle battery.
If the vehicle battery voltage drops below 12.0V or above 15.5V during
reprogramming, the ECM may be damaged.

•

Be sure to turn OFF all vehicle electrical loads.
If a vehicle electrical load remains ON, the ECM may be damaged.

•

Be sure to connect the AC Adapter.
If the CONSULT PC battery voltage drops during reprogramming, the process
will be interrupted and the ECM may be damaged.

•

Turn off all external Bluetooth® devices (e.g., cell phones, printers, etc.) within
range of the CONSULT PC and the VI. If Bluetooth® signal waves are within
range of the CONSULT PC during reprogramming, reprogramming may be
interrupted and the ECM may be damaged.

B. Compare the P/N you wrote down to the numbers in the Current ECM Part Number
column in Table A below.
•

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.
¾ In this case, the screen in Figure 3 displays.
¾ 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.
