Normal Operation and Fault Conditions
The SCCM receives battery voltage from the BCM and has a single ground circuit located in the instrument panel wiring harness. Excessive resistance or an open in one or both of these circuits, a discharged battery, an inoperative charging system or an overcharging condition in the charging system results in the SCCM setting a DTC.
This DTC may also set in the SCCM due to battery charging or vehicle jump starting events.
