Disconnection of the Negative Battery Cable
• Before beginning any electrical work, turn the igni-
tion switch to LOCK, disconnect the negative bat-
tery cable and then wait two minutes to allow the
backup supply of the air bag diagnostic monitor unit
to deplete its stored power.
• Disconnecting the battery cable deletes the memo-
ries of the clock, audio and DTCs, etc. Therefore, it
is necessary to verify those memories before dis-
connecting the cable.
