Control Module Service Precautions

The control module is designed to withstand the normal current draws that are associated with the vehicle operations. Avoid overloading any circuit. When testing for opens or shorts, do not ground any of the control module circuits unless instructed. When testing for opens or shorts, do not apply voltage to any of the control module circuits unless instructed. Only test these circuits with J 39200 Digital Multimeter (DMM), while the control module electrical connectors remain connected to the control module.
