Circuit/System Description
The vehicle control modules or sensors monitor the system voltage to verify the system voltage is within the normal operating range.
Conditions for Running the DTC
The engine is running.
Conditions for Setting the DTC
The control module or sensor detects a system voltage of less than approximately 9 V or greater than 18 V for approximately 5 seconds.
Action Taken When the DTC Sets
* A driver information center message and/or warning indicator may be displayed.
* The control module may be temporarily disabled.
Conditions for Clearing the DTC
The system voltage returns to normal operating range.
Diagnostic Aids
* A high or low voltage DTC set or voltage value in multiple modules/sensors indicates a concern in the charging system.
* A possible cause of this DTC could be overcharging with a battery charger or jump starting.

Circuit/System Verification
1. Ignition OFF, measure and record the battery voltage at the battery terminals.
2. Verify the battery voltage stabilizes between 12.4 and 12.8 V within a few minutes of turning the ignition OFF.
• If battery voltage is less than 12.4 V or more than 12.8 V
Refer to Battery Inspection/Test Battery Inspection/Test.
• If battery voltage is between 12.4 and 12.8 V
3. Engine running, headlights ON, measure and record the battery voltage at the battery terminals.
4. Verify the voltage is at least 1 V greater than the voltage measured in step 1, but less than 15 V.
• If the voltage is not at least 1 V greater than the voltage measured in step 1 or is greater than 15 V.
Refer to Charging System Test Testing and Inspection.
• If the voltage is at least 1 V greater than the voltage measured in step 1, but less than 15 V.
5. Verify the appropriate control module scan tool B+ and ignition voltage parameters are within 1 V of the battery voltage.
• If not within 1 V of the battery voltage
Refer to Circuit/System Testing.
• If within 1 V of the battery voltage
6. All OK.
Circuit/System Testing
Note: Use the schematic to identify the following:
* Control modules the vehicle is equipped with
* The control modules ground, B+, and Ignition circuit terminal IDs and connectors
Note: Some control module ground circuits may require up to 20 minutes after the ignition is turned off before achieving a resistance reading of less than 5 ohms. In most cases the readings will drop below 20 ohms within 1 minute indicating the control module is going to sleep.
1. Ignition OFF and all vehicle systems OFF, disconnect the harness connectors at the appropriate control module. It may take up to 2 minutes for all vehicle systems to power down.
2. Test for less than 10 ohms between each ground circuit terminal and ground.
• If 10 ohms or greater
1. Ignition OFF.
2. Test for less than 2 ohms in the ground circuit end to end.
• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, repair the open/high resistance in the ground connection.
• If less than 10 ohms
3. If equipped, verify a test lamp illuminates between each B+ circuit terminal and ground.
• If the test lamp does not illuminate and the circuit fuse is good
1. Ignition OFF.
2. Test for less than 2 ohms in the B+ circuit end to end.
• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, verify the fuse is not open and there is voltage at the fuse.
• If the test lamp does not illuminate and the circuit fuse is open
1. Ignition OFF.
2. Test for infinite resistance between the B+ circuit and ground.
• If less than infinite resistance, repair the short to ground on the circuit.
• If infinite resistance, replace the appropriate control module.
• If the test lamp illuminates
4. Ignition ON.
5. If equipped, verify a test lamp illuminates between each ignition circuit terminal and ground.
• If the test lamp does not illuminate and the circuit fuse is good
1. Ignition OFF.
2. Test for less than 2 ohms in the ignition circuit end to end.
• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, verify the fuse is not open and there is voltage at the fuse.
• If the test lamp does not illuminate and the circuit fuse is open
1. Ignition OFF.
2. Test for infinite resistance between the ignition circuit and ground.
• If less than infinite resistance, repair the short to ground on the circuit.
• If infinite resistance, replace the appropriate control module.
• If the test lamp illuminates
6. Replace the control module.
