Disabling & Activating Air Bag System

WARNING: This page is about a different car, the 1994 Chrysler LeBaron. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Wait at least 2 minutes after disconnecting negative battery cable before servicing air bag system. System reserve capacitor, integral to ACM, maintains air bag system voltage for about 2 minutes after battery is disconnected. Servicing air bag system before 2 minutes may cause accidental air bag deployment and possible personal injury.
CAUTION: When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES in GENERAL INFORMATION before disconnecting battery.
  1. To disable air bag system for repairs, ensure ignition switch is in OFF position. Disconnect negative battery cable, and tape cable end. Wait at least 2 minutes after disconnecting negative battery cable before servicing air bag system.
  2. To activate air bag system, reconnect negative battery cable. Turn ignition on. Observe AIR BAG warning light. Warning light should come on for 6-8 seconds and then go out, indicating system is functioning properly. If warning light fails to glow, or glows and stays on, a system malfunction exists. See SYSTEM OPERATION CHECK.
