Diagnostic Procedure
WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
- If SIR diagnostic system check has been performed, go to next step. If SIR diagnostic system check has not been performed, go to SIR DIAGNOSTIC SYSTEM CHECK .
- Turn ignition off. Disconnect passenger-side air bag module connector, located under instrument panel. See Figure. If harness connector is damaged or corroded, go to next step. If harness connector is okay, go to step 4.
- If harness side of connector is damaged, replace connector. See WIRE REPAIR . Go to step 11. If passenger side air bag module pigtail connector is damaged, go to step 10.
- Turn ignition off. Install SIR Driver/Passenger Load Tool (SA9409Z-A) using Load Tool Adapter (SA9409Z-99P) to passenger-side air bag module harness connector. Turn ignition on. Using scan tool, check for SIR DTC's. If DTC B0017 is retrieved, go to next step. If DTC B0017 is not retrieved, go to step 10.NOTE: Use Digital Multimeter (SA911141NE) and Connector Test Adapter Kit (SA9206Z) when performing electrical tests.
- Turn ignition off. Remove SIR load tool and load tool adapter from harness connector. Disconnect SDM harness connector. See Figure. Measure resistance of White/Black wire between SDM connector terminal A4 and passenger-side air bag harness connector terminal "A". If resistance is one ohm or less, go to step 7. If resistance is more than one ohm, go to next step.
- Repair open or high resistance in circuit 1404. See WIRE REPAIR . Go to step 11.
- Measure resistance of Dark Green/White wire between SDM connector terminal A3 and passenger-side air bag harness connector terminal "B". If resistance is one ohm or less, go to step 9. If resistance is more than one ohm, go to next step.
- Repair open or high resistance in circuit 1404. See WIRE REPAIR . Go to step 11.
- Replace SDM. See SENSING & DIAGNOSTIC MODULE (SDM) under REMOVAL & INSTALLATION. Go to step 11.
- Replace passenger-side air bag module. See AIR BAG MODULES under REMOVAL & INSTALLATION. Go to next step.
- Reconnect all SIR components. Ensure that all components are properly mounted. Using scan tool, clear all SIR DTC's. Go to SIR DIAGNOSTIC SYSTEM CHECK .
