Battery Cable Replacement Battery Disconnect/Connect

Disconnecting the Negative Battery Cable for Service

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. Record all preset and theft codes from the radio.
  2. Turn the ignition switch to the LOCK position.
  3. Verify that all electrical components are off such as interior lights, all doors are closed, underhood lamp etc.
  4. Remove the retaining bolt from the battery negative cable.
  5. Remove the battery negative cable from the battery.
  6. Position the battery negative cable away from any body ground.
  7. Remove the auxiliary battey negative cable if equipped with two batteries.

Connecting the Negative Battery Cable for Service
  1. Verify that all electrical components are off such as interior lights, all doors are closed, underhood lamp etc.
  2. Clean the negative battery cable from corrosion using a metal brush.
  3. Install the auxiliary battery negative cable to the battery.

    4. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
