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 ignition is ON.

Conditions for Setting the DTC

The control module or sensor detects a system voltage of less than approximately 9 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. The battery voltage should stabilize between 12.4 and 12.8 V within a few minutes of turning the ignition OFF.

2. If not within the specified range, refer to Battery Inspection/Test .

3. Run the engine and have the accessories off. Measure and register the battery voltage at the battery connections. The voltage should be at least 1 V greater than the voltage measured in step 1 but less than 15 V.

4. If not within the specified range, refer to Charging System Test .

5. Observe the appropriate module scan tool B+ and ignition voltage parameters. The voltage readings should be within 1 V of the battery voltage.


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



1. Ignition OFF, disconnect the harness connectors at the appropriate control module.

2.
Note

Some control module ground circuits may require up to 20 minutes to achieve a resistance reading of less than 10 Ω. In most cases the readings will drop below 20 Ω within 1 minute indicating the control modules are going to sleep.


Ignition OFF, scan tool disconnected, open and close the driver door. Wait 1 minute. Test for less than 10 Ω between each ground circuit terminal and ground.

3. If greater than the specified range, test the ground circuit for an open/high resistance.

4. If equipped, verify that a test lamp illuminates between each B+ circuit terminal and ground.

5. If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.

6.
Note

If the ignition circuit in Step 4 is providing voltage from a relay that has its coil grounded through the control module connector, you will have to connect a fused jumper wire from the relay ground to a good ground to verify the ignition circuit works properly.


If equipped, ignition ON, verify that a test lamp illuminates between each ignition circuit terminal and ground.

7. If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.

8. If all circuits test normal, replace the control module module.


Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
