Battery Inspection/Test Acadia or Enclave

Tools Required

J 42000 Battery Tester

Caution: Refer to Battery Disconnect Caution in the Preface section.

Important: The battery test using the J 42000 Battery Tester requires correct connections to the battery terminals. A failure to obtain the correct connections during the test may result in a failed test on a good battery.

If testing the vehicle with the battery cables still connected, wiggle the J 42000 clips on the terminal. This may cut through any coating or through any oxidation that may be present on the terminal.

Even new terminals contain a protective coating that may insulate or cause a resistance in the test circuit.

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

1. Inspect the battery for a cracked, broken, or damaged case, which may be indicated by battery acid leakage.

⇒	If there is any apparent damage, replace the battery.

2. Verify the cold cranking amperage (CCA), and reserve capacity (RC) and/or amp hour (AH) rating of the battery to the original battery or original equipment (OE) specification. Refer to Battery Usage.

⇒	If the battery does not meet or exceed specifications, replace the battery.

3. Verify that the battery cables are clean and tight. The battery terminal bolts should be torqued as specified in Fastener Tightening Specifications.

⇒	If the battery cable(s) need to be cleaned, clean as required and tighten as specified.

⇒	If the battery cable(s) are damaged, replace then tighten as specified.

4. Install the J 42000 and follow directions supplied by the tester.

⇒	If the tester calls for charging the battery, refer to Battery Charging.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
