DO NOT contact the control module metal case withbattery voltage when servicing a control module, using batterybooster cables, or when charging the vehicle battery.In order to prevent any possible electrostatic dischargedamage to the control module, do no touch the connector pins or thesoldered components on the circuit board.Remove any debris from around the control module connectorsurfaces before servicing the control module. Inspect the controlmodule connector gaskets when diagnosing or replacing the controlmodule. Ensure that the gaskets are installed correctly. Thegaskets prevent contaminant intrusion into the controlmodule.The replacement control module must be programmed.
