Test D: Remote Anti-Theft Personality (Rap) Module Does Not Respond To NGS Tester
- Turn ignition off. Disconnect RAP module 26-pin Gray connector C336 located behind left rear quarter panel. Inspect connector for physical damage, bent terminals or corrosion. Repair connector as necessary and retest system for normal operation. If connector is okay, go to next step.
- Measure resistance of Light Blue/White wire between terminal No. 3 at RAP module 26-pin connector and terminal No. 7 at Data Link Connector (DLC). See Figure and Figure. If resistance is less than 5 ohms, replace RAP module and retest system for normal operation. If resistance is 5 ohms or more, go to next step.
- Disconnect and inspect both halves of bulkhead connector C212 located at left corner of instrument panel, near cowl panel grommet. See Figure. Inspect connector for physical damage, bent terminals or corrosion. Repair connector as necessary and retest system for normal operation. If connector is okay, go to next step.
- Measure resistance of Light Blue/White wire between terminal No. 3 at RAP module 26-pin connector and terminal No. 51 at male half of bulkhead connector C212. See Fig 1. If resistance is less than 5 ohms, repair open in Light Blue/White wire between female half of bulkhead connector C212 and DLC. Retest system for normal operation. If resistance is 5 ohms or more, repair open in Light Blue/White wire between RAP module 26-pin connector and male half of bulkhead connector C212. Retest system for normal operation.
