Service Procedure

SERVICE PROCEDURE

Reprogram VCM (Vehicle Control Module)


1. Before continuing, it is IMPORTANT to make sure:

^ ASIST on the CONSULT PC has been freshly synchronized (updated).

^ All CONSULT related software updates (if any) have been installed.

NOTE:
The CONSULT PC automatically gets all reprogramming software during ASIST synchronization.





CAUTION

2. Have the GR8 Multitasking Battery Diagnostic Station (battery tester/charger) available and ready to use.

^ For proper setup, go to "GR8 Multitasking Battery Diagnostic Station Setup".

^ Do not connect the battery tester/charger at this time. The battery tester/charger will be set up later in this bulletin.

CAUTION:
Do not charge the High Voltage (HV) Lithium Ion battery during reprogramming.

NOTES:
> If a Mobile Technician performs the VCM reprogram, make sure a fully charged 12 V battery (with jumper cables) or portable battery charger is used.

> Check to see if the timer for either charging or climate control is on. If on, make sure to turn it back on after reprogramming.

3. Once all ASIST and CONSULT related updates have been verified/performed, attach the CONSULT PC to vehicle.

^ Connect the plus VI to the vehicle.

^ Connect the CONSULT PC to the plus VI with the USB cable.
