Diagnostic Aids
• A possible cause of this DTC could be overcharging
with a battery charger or jump starting.
• A high voltage value in multiple modules indicates a
concern in the charging system.
Circuit/System Verification
1. Verify DTC C0900 is set as current.
➢ If the DTC is history, refer to "Charging System
Test"
2. Start the engine, record the voltage at the battery
terminals. Observe the scan tool EBCM battery
voltage signal parameter. Voltages should not differ
by more than 1 volt.
➢ If greater than 1 volt, replace the EBCM.
