This Preliminary Information communication provides information to the technician on the steps to diagnose and repair vehicles that may have a Service Charging System, Battery Saver message Or Malfunction Indicator Lamp on, and/or charging system inoperative. Technician will use Global Diagnostic System 2 and clear the Diagnostic Trouble Codes in the Hybrid Powertrain Control Module and the Battery Energy Control Module. Then turn the ignition off for a minimum of 2 minutes to allow the high speed local area network and powertrain expansion bus to power down. Start the car and monitor the charging system voltage.
