- Test for greater than 12 V between the battery positive terminal and negative terminal.
- If 12 V or less
Refer to Battery Inspection/Test .
- Go to next step: If greater than 12 V
- If 12 V or less
- Verify the scan tool parameter:
- Battery Sensor Module Battery State Information parameter reads Available.
- Battery Sensor Module Reset Occurred - Using Estimated State of Charge reads No.
- If not the specified value
- Disconnect and reconnect the C1 Battery Negative cable.NOTE:
Allowing the vehicle to sit undisturbed for 3 h will automatically perform a Battery Sensor Learn upon the next engine cranking event. This will allow the battery state of charge to be relearned.
- Wait a minimum of 3 hours.
- Start the engine.
- Test drive the vehicle.
