Air Bag Simulator (40-009) MUST be connected to all air bag floor harness connectors. After diagnosis/repair, air bag simulator must be removed prior to operating vehicle.
- Disconnect passenger seat control switch harness connector. See Fig 1. Measure voltage between ground and seat control switch harness connector terminal No. 7 (Red/White wire). If battery voltage exists, go to next step. If battery voltage does not exist, repair open in Red/White wire between battery junction box and seat control switch. See WIRING DIAGRAMS .
- Measure resistance between ground and seat control switch harness connector terminal No. 1 (Black wire). If resistance is 5 ohms or less, replace seat control switch. See SEAT CONTROL SWITCH under REMOVAL & INSTALLATION. If resistance is more than 5 ohms, repair open in Black wire between seat control switch and ground. Ground point is located near fuel tank.
