Periodically inspect the entire length of each battery cable for damage, cracked or burned insulation, and corrosion, as poor connections can lead to starting problems and reduced engine performance. Examine cable-to-terminal connections for cracks, loose wire strands, and corrosion, especially if white, fluffy deposits are found under the insulation at the cable terminal connection. Always disconnect the negative cable from the negative battery post first, even if only replacing the positive cable, to prevent accidental shorting. Before disconnecting any cables, note their routing, then disconnect them at both ends. The ground cable attaches to the body at the battery tray, and another connects the transaxle to the chassis. When replacing the negative cable, disconnect the electrical connector from the battery current sensor and remove the tape securing it. The positive cable runs forward under the vehicle to the remote positive post on the fuse/relay box, and a shorter one goes to the starter motor. The long positive cable runs from the trunk to the engine compartment, and when replacing it, remove the underhood fuse/relay box, release the cable from plastic ties, and access it by removing seats and carpeting if necessary. Ensure you replace cables with identical parts, usually red for positive and black for ground. Clean threads on the starter solenoid or ground connection with a wire brush, applying corrosion inhibitor or petroleum jelly. Attach lower cable ends first, then the positive cable to the battery post. Secure the battery current sensor on the new negative cable and use electrical tape. Attach the cables to the wiring harness with cable ties, reinstall brackets or clips if needed, and reconnect the ground cable to the negative battery post. After disconnecting the battery, note that the PCM must relearn its former drivability and performance characteristics.
