Initial Inspection and Diagnostic Overview

Rotunda Air Bag Simulator 105-00008 or equivalent is required to perform diagnosis and testing of the air bag system. The air bag simulator is a 1 ohm resistor used to simulate an air bag connection to the system. It is not acceptable to jump out the air bag connection with a zero ohm jumper wire. If a zero ohm jumper wire is used to jumper out the air bag connection, a system fault will be displayed (Fault Code 34 or 35) according to the priority scheme.

Deactivation Procedure
1. Disconnect positive battery cable.
2. Wait one minute. This is the time required for backup power supply in diagnostic monitor to deplete its stored energy.
3. Remove four nut and washer assemblies retaining driver air bag module to steering wheel. Disconnect driver air bag connector. Connect Rotunda Air Bag Simulator 105-00008 or equivalent to vehicle harness at top of steering wheel.
4. If vehicle is equipped with passenger air bag, remove passenger air bag. The connector will contain the 614 (GY/O) and 616 (PK/BK) circuits. Install air bag simulator on vehicle harness connector.
5. Connect positive battery cable.

Reactivation Procedure
1. Disconnect positive battery cable.
2. Wait one minute for backup power supply to deplete stored energy.
3. Remove air bag simulator from vehicle harness connector at top of steering column. Reconnect driver air bag connector. Position driver air bag on steering wheel and secure with four nut and washer assemblies (10 mm). Tighten nut and washer assemblies to 2.7-3.7 N.m (24-32 lb-in).
4. If vehicle is equipped with passenger air bag, remove air bag simulator from vehicle harness connector. Reconnect passenger air bag.
5. Connect positive battery cable.
6. Prove-out system.

WARNING: THE AIR BAG SIMULATOR(S) MUST BE REMOVED AND THE AIR BAG(S)RECONNECTED WHEN THE SYSTEM IS REACTIVATED.
