Diagnostic Procedure
WARNING: This page is about a different car, the 2000 Chevrolet Corvette. 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 air bag module 4-pin inline connector. Check male and female sides of connector for corrosion, damaged terminals or poor connections. If corrosion, damaged terminals or poor connections are found, go to next step. If no corrosion, damaged terminals or poor connections are found, go to step 4 .
- If male side of connector is damaged, replace connector. If female side of connector is damaged, replace wiring harness. See WIRE REPAIR . Go to step 14 .
- Reconnect 4-pin connector. Ensure CPA clip is installed correctly. Turn ignition on. Using scan tool, check for SIR DTCs. If DTC B0016 is retrieved, go to next step. If DTC B0016 is not retrieved, go to DIAGNOSTIC AIDS.
- Turn ignition off. Disconnect passenger air bag module 4-pin connector. Install SIR Driver-Passenger Load Tool (J-38715-A) to harness connector. Turn ignition on. Using scan tool, check for SIR DTCs. If DTC B0016 is retrieved, go to step 11 . If DTC B0016 is not retrieved, go to next step.
- Turn ignition off. Disconnect passenger-side air bag module inline 2-pin connector. Inspect both sides of connector for corrosion, damaged terminals or poor connections. If damage is found, go to next step. If no damage is found, go to step 8 .
- If female side of connector is damaged, replace connector. If male side of connector is damaged, passenger-side air bag module must be replaced. See AIR BAG MODULES under REMOVAL & INSTALLATION. Go to step 14 .
- Remove SIR Driver-Passenger Load Tool (J-38715-A) from 4-pin connector. Reconnect 4-pin connector. Install SIR Driver-Passenger Load Tool (J-38715-A) to female side of passenger-side air bag module 2-pin inline connector. Turn ignition on. Using scan tool, request DTC display. If DTC B0016 is retrieved, go to next step. If DTC B0016 is not retrieved, go to step 10 .
- Turn ignition off. Repair short between circuits 1403 and 1404 between 2-pin and 4-pin connectors. Go to step 14 .
- Turn ignition off. Replace passenger-side air bag. See AIR BAG MODULES under REMOVAL & INSTALLATION. Go to step 14 .
- Turn ignition off. Remove SIR Driver-Passenger Load Tool (J-38715-A) from harness connector. Disconnect SDM harness connector. Using Digital Multimeter (J-39200), measure resistance between SDM harness connector terminals No. A3 and A8. See Figure . If resistance is infinite, go to next step. If resistance is not infinite, go to step 13 .
- Repair short between circuits 1403 and circuit 1404. Go to step 14 .
- Replace SDM. See SENSING & DIAGNOSTIC MODULE (SDM) under REMOVAL & INSTALLATION.Go to next step.
- Reconnect all SIR components. Ensure that all components are properly mounted. Clear all SIR DTCs. Go to SIR DIAGNOSTIC SYSTEM CHECK .
