It has been found during warranty part reviews of the TCM at the Warranty Parts Center (WPC) that the TCM is possibly being shorted to battery voltage during vehicle diagnosis and/or repairs when the vehicle is brought to the dealer for any number of reasons.

It has been found that if the positive battery jump start post/terminal cover is removed and/or missing, and the TCM comes in contact with the positive battery jump start post/terminal during diagnosis and/or service, the TCM WILL BE DAMAGED and require replacement.

Service Precautions
• Prior to removing the TCM from its mounting bracket, disconnect the negative battery cable. Refer to the appropriate SI Document.

• If service requires the negative battery cable to be installed for diagnostic purposes, unplug the TCM before it is removed from its mounting bracket. Unplugging the TCM will eliminate the possibility of damaging the module during diagnosis and/or repair.

Caution: Control module damage may result when the metal case contacts battery voltage. DO NOT contact the control module metal case with battery voltage when servicing a control module, using battery booster cables, or when charging the vehicle's battery. DO NOT us the TCM or its mounting bracket/fasteners as the ground connection when jump-starting.

DO NOT allow the TCM to come in contact with the positive battery jump start post/terminal during diagnosis and/or repairs.

Positive Battery Jump Post/Terminal (Remote Positive Terminal) Location
The location of the positive battery jump post/terminal for each vehicle (excluding Express and Savana) is shown in the following illustrations. Do NOT allow any part of the TCM to come into contact with the positive battery jump start post/terminal.
