Test 22A: Passenger-Side Air Bag On-Off Switch Open
WARNING: This page is about a different car, the 2004 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Prior to performing any air bag system test, go to PRETEST INSPECTION & DIAGNOSTIC PROCEDURE under DIAGNOSTICS. Perform TEST VER-1: AIR BAG VERIFICATION TEST after all repairs unless otherwise directed.
- Turn ignition switch to ON position. Using DRBIII, determine if PASSENGER-SIDE AIR BAG ON-OFF SWITCH OPEN is an active or stored Diagnostic Trouble Code (DTC). If PASSENGER-SIDE AIR BAG ON-OFF SWITCH OPEN is an active DTC, go to next step. If PASSENGER-SIDE AIR BAG ON-OFF SWITCH OPEN is a stored DTC, go to TEST 1B: REPAIRING STORED CODES .
- Disable air bag system. See DISABLING SYSTEM under DISABLING & ACTIVATING AIR BAG SYSTEM. Access passenger-side air bag on-off switch and disconnect harness connector. See PASSENGER-SIDE AIR BAG ON-OFF SWITCH under REMOVAL & INSTALLATION. Measure resistance between component side of passenger-side air bag on-off switch connector terminals No. 1 and 2 with switch in ON position. See Fig 1. Measure resistance between component side of passenger-side air bag on-off switch connector terminals No. 1 and 2 with switch in OFF position. If resistance is 175-190 ohms with switch in ON position and 820-870 ohms with switch in OFF position, go to next step. If resistance is not 175-190 ohms with switch in ON position and 820-870 ohms with switch in OFF position, replace passenger-side air bag on-off switch.
- Access Air Bag Control Module (ACM) and disconnect harness connector. See AIR BAG CONTROL MODULE (ACM) under REMOVAL & INSTALLATION. Measure resistance between harness side of ACM connector terminal No. 19 and harness side of passenger-side air bag on-off switch connector terminal No. 2 (Light Green/Dark Green wire). See Figure & Fig 1 . Measure resistance between harness side of ACM connector terminal No. 20 and harness side of passenger-side air bag on-off switch connector terminal No. 1 (Light Green/Orange wire). If resistance is less than 5 ohms in both circuits, replace ACM. If resistance is more than 5 ohms in either circuit, repair open in appropriate wire. See WIRING DIAGRAMS .
