Vehicle OFF.
Measure and record the C1 battery voltage at the C1 battery terminals. The C1 battery voltage should stabilize between 12.4 and 12.8 V within a few minutes of turning the vehicle OFF.
- If not within the specified range
  Refer to Battery Inspection/Test .
- If within the specified range
Vehicle ON, accessories OFF.
Measure and record the C1 battery voltage at the C1 battery terminals. The voltage should be at least 1 V greater than the voltage measured in step 1 but less than 15.6 V.
- If not within the specified range
  Refer to Circuit/System Testing.
- If within the specified range
All OK.
