To disarm the air bag system, simply disconnect the negative battery cable from the battery. Isolate the battery cable by taping up any exposed metal areas of the cable. This will keep the cable from accidentally contacting the battery and causing deployment of the air bag. Allow the system capacitor to discharge for at least 2 minutes, although 10 minutes is recommended, to allow for the dissipation of any residual energy.
To arm the system, reconnect the negative battery cable. This will automatically enable the system.
See Figures 3 through 9
CAUTION
Before performing this procedure, disable the air bag system. Failure to do so could result in accidental air bag deployment and possible injury.
Disconnect the negative battery cable and disable the air bag system.
