Circuit/System Verification

NOTE:

Verify Stop/Start system related campaigns or special policies have been completed prior to proceeding.

Ignition OFF, measure and record the battery voltage at the battery terminals.
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 .
- Go to next step: If battery voltage is between 12.4 and 12.8 V
Engine running, headlights ON, measure and record the battery voltage at the battery terminals.
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 .
- Go to next step: If the voltage is at least 1 V greater than the voltage measured in step 1, but less than 15 V.
Inspect the wiring circuits to the B110 Battery Sensor Module for proper routing and/or damage.
- If a condition is found
  Repair the condition.
- Go to next step: If no condition is found
Verify no current or history DTCs are set for devices on LIN circuit 2855.
- If any DTCs are set
  Refer to Diagnostic Trouble Code (DTC) List - Vehicle .
- Go to next step: If no DTCs are set
Refer to Circuit/System Testing.
