SERVICE PROCEDURE
REPROGRAM THE ECM
IMPORTANT: Before starting, make sure:

ASIST on the CONSULT PC has been synchronized (updated) to the current date.

All CONSULT-III plus (C-III plus) software updates (if any) have been installed.

The CONSULT PC is connected to the Internet (Wi-Fi or cable).
NOTE:

Most instructions for reprogramming with 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 "CONSULTIII plus (C-III plus) ECM 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. The
above conditions are required for the IAVL to complete.
Figure A
CAUTION:

Connect the GR8 to the 12V battery and select ECM Power Supply Mode.
If the vehicle battery voltage goes 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 plus VI. If Bluetooth® signal waves are within range of the CONSULT PC and
plus VI during reprogramming, reprogramming may be interrupted and the ECM may be damaged.

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 1 displays.
 Select and use the reprogramming option that does not have the message “Caution! Use ONLY
with ITBXX-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.
