Disarming the System


To avoid rendering the Supplemental Restraint System (SRS) inoperative, which could lead to personal injury or death in the event of a severe frontal collision, extreme caution must be taken when servicing the electrical related systems.

All SRS electrical wiring harnesses and connectors are covered with YELLOW outer insulation. Do not use electrical test equipment on any circuit related to the SRS (air bag) sensors. When installing SRS components, always install with the arrow marks facing the front of the vehicle.

To disarm the Supplemental Restraint System (SRS) system turn the ignition switch to the OFF position. Then, disconnect the both battery cables starting with the negative cable first and wait at least 10 minutes after the cables are disconnected. Be sure to insulate the battery terminal ends.

The air bag system must be disarmed before performing service around air bag components or wiring. Failure to do so may cause accidental deployment of the air bag, resulting in unnecessary repairs and/or personal injury.

  1. Position the vehicle with the front wheels in a straight ahead position.
  3. Disconnect the negative battery cable.
  5. Disconnect the positive battery cable.
  7. Wait at least ten minutes for the air bag back-up power supply to drain before continuing.
  9. Proceed with the repair.
  11. Once complete, connect the battery cables, negative cable last.
  13. Check the functioning of the air bag system by turning the ignition key to the RUN position and visually monitoring the air bag indicator lamp in the instrument cluster. The indicator lamp should illuminate for approximately seven seconds, then turn OFF . If the indicator lamp does not illuminate, stays on, or flashes at any time, a fault has been detected by the air bag diagnostic monitor.
