Disconnection of the Negative Battery Cable

Disconnection of the Negative Battery Cable

- Before beginning any work, turn the ignition switch to LOCK, disconnect the negative battery cable and then wait for more than one minute to allow the backup supply of the air bag diagnostic monitor unit to deplete its stored power.

Disconnecting the battery cable will delete the memories of the clock, audio and DTCs, etc. Therefore, it is necessary to verify those memories before disconnecting the cable.
