* The control module immediately disables all outputs when an out of range voltage condition has been detected, with the exception of serial
data, which is disabled after a 3 minute delay.
* The setting of other DTCs is inhibited.
Conditions for Clearing the DTC
The DTC passes when the malfunction is no longer present.
Diagnostic Aids
* A high or low voltage value in multiple modules indicates a concern in the charging system.
* Overcharging with a battery charger or jump starting can cause this DTC to set.

Circuit/System Verification
1. Engine running, accessories OFF, measure and record the battery voltage at the battery terminals. The voltage should be between 12.6 and
15.0 V.
瀚慖f the battery voltage is not within the specified range, refer to Charging System Test (See: Starting and Charging/Testing and
Inspection/Component Tests and General Diagnostics/Charging System Test)
2. Observe the appropriate module scan tool Battery Voltage parameters. Verify that the scan tool displays a value that is within 2 V of the
battery terminal voltage.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connectors of the appropriate control module.
2. Ignition OFF and scan tool disconnected, open and close the driver door, and wait 1 minute. Test for less than 5 Ohms between the ground
circuits listed below and ground.

* Terminal 38 X1 (Radio)
* Terminal 10 X1 (HVAC)
