- Turn ignition off. Disconnect air bag diagnostic monitor Black connector C208 located behind right side of instrument panel. See Fig 1 . Inspect air bag diagnostic monitor connector C208 and Data Link Connector (DLC) C228 for physical damage, bent terminals or corrosion. Repair as necessary and retest system. If connectors are okay, go to next step.
- Measure resistance of Light Blue/White wire between air bag diagnostic monitor connector C208, terminal No. 12 and DLC C228, terminal No. 7. See Figure and Fig 1 . If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open in Light Blue/White wire between air bag diagnostic monitor C208 connector and DLC C228. Retest system.
- Reconnect air bag diagnostic monitor connector C208. Repeat DATA LINK DIAGNOSTICS test. If air bag diagnostic monitor responds to NGS tester, system is functioning properly. If air bag diagnostic monitor does not respond to NGS tester, replace air bag diagnostic monitor and retest system.
