Diagnostics Disabling Procedure

This procedure should only be used when performing air bag system diagnostics or repairs.

1. Record pre-set radio frequencies for reprogramming. Disconnect negative battery cable. Wait at least one minute for back-up power supply to deplete stored energy.
2. Remove lower steering column opening cover. Disconnect Yellow 4-pin lower clockspring connector. See Figure . Connect Air Bag Simulator (418-F403) to vehicle harness side of lower clockspring connector.
3. Remove dual-stage passenger-side air bag module. See DUAL-STAGE PASSENGER-SIDE AIR BAG MODULE  under REMOVAL & INSTALLATION. Connect Air Bag Simulator (418-F403) to vehicle harness side of passenger-side air bag module connector (in place of dual-stage air bag). See Figure .
   CAUTION: Air bag system fault is possible. Some models are not equipped with side air bags. Side air bag bridge resistors are installed in place of side air bags on these models. Removing air bag bridge resistor can cause low resistance fault. Do not remove side air bag bridge resistors during deactivation procedure unless directed.
   NOTE: Air bag simulator for driver (418-F405) and passenger (418-F407) seat belt pretensioners are similar but not interchangeable. Ensure correct tool is installed on correct connector.
4. Remove left and right front seats. See FRONT SEAT  under REMOVAL & INSTALLATION. On models equipped with side air bags, connect Air Bag Simulator (418-133) to vehicle harness side of each side air bag floor connector. On all models, connect Air Bag Simulator (418-F405) to driver-side 10-pin floor connector. Connect Air Bag Simulator (418-F407) to passenger-side 10-pin floor connector. Connect negative battery cable.
