Test D: Remote Anti-Theft Personality Module Does Not Respond To NGS Tester
- Turn ignition switch to LOCK position. Disconnect Remote Anti-Theft Personality (RAP) module 26-pin harness connector C336. Inspect connector for physical damage, bent terminals or corrosion. If connector is okay, go to next step. If connector is damaged, repair connector as necessary and recheck system operation.
- Measure resistance of Light Blue/White wire between RAP module harness connector C336 terminal No. 3 and Data Link Connector (DLC) terminal No. 7. See Figure and Figure
. If resistance is 5 ohms or more, go to next step. If resistance is less than 5 ohms, replace RAP module and recheck system operation.
- Disconnect and inspect both halves of bulkhead 84-pin harness connector C212, located at left corner of instrument panel near cowl panel grommet. See Figure. Inspect connector for physical damage, bent terminals or corrosion. If connector is okay, go to next step. If connector is damaged, repair connector as necessary and recheck system operation.
- Measure resistance of Light Blue/White wire between RAP module harness connector C336 terminal No. 3 and male half of bulkhead harness connector C212 terminal No. 51. See Figure and Fig 1
. If resistance is less than 5 ohms, repair open in Light Blue/White wire between female half of bulkhead harness connector C212 and DLC. Recheck system operation. If resistance is 5 ohms or more, repair open in Light Blue/White wire between RAP module harness connector C336 and male half of bulkhead harness connector C212. Recheck system operation.
