SERVICE PROCEDURE

TCM REPROGRAMMING

• ASIST on the CONSULT PC has been synchronized (updated) to the current date.
• All C-III plus software updates (if any) have been installed.
• The CONSULT PC is connected to the internet (Wi-Fi, or cable).

1. Connect the plus Vehicle Interface (plus VI) to the vehicle.
   CAUTION: Make sure the plus VI is securely connected. If the plus VI connection is loose during reprogramming, the process will be interrupted and the TCM may be damaged.
2. Connect the AC Adapter to the CONSULT PC.
   CAUTION: Be sure to connect the AC Adapter. If the CONSULT PC battery voltage drops during reprogramming, the process will be interrupted and the TCM may be damaged.
3. Connect the GR8, set to "Power Supply" mode, to the vehicle battery.
   CAUTION: Be sure the GR8 is connected securely to the battery. Make sure the battery voltage stays between 12.0V and 15.5V  during reprogramming. If the battery voltage goes out of this range during reprogramming, the TCM may be damaged.
4. Turn OFF all external Bluetooth® devices (e.g., cell phones, printers, etc.) within range of the CONSULT PC and the VI.
   CAUTION: Make sure to turn OFF all external Bluetooth® devices. If Bluetooth® signal waves are within range of the CONSULT PC and the plus VI during reprogramming, reprogramming may be interrupted and the TCM may be damaged.
5. Turn the ignition ON with the engine OFF.
   • The engine must not start or run during the reprogramming procedure. 
6. Turn OFF all vehicle electrical loads such as exterior lights, interior lights, HVAC, blower, rear defogger, audio, NAVI, seat heater, steering wheel heater, etc.
