Yes disconnect the battery and wait 20 mins then have a gander at the wires, do not un-necessarily unplug and plug the connectors unless they look like water may have corroded them, they are very special in that the air bag side is shorted out once unplugged, this is to stop idiots from testing with an Ohm meter and possibly setting it off, trouble is on reconnecting you cannot be sure the shorting link has reset itself correctly, look for chaffed wires etc, Rick
