Test B: Remote Anti-Theft Personality (Rap) Module Does Not Respond To NGS Tester

NOTE: After making any repair, perform data link diagnostic test. See DATA LINK DIAGNOSTIC TEST  under SELF-DIAGNOSTIC SYSTEM.
  1. Turn ignition switch to LOCK position. Disconnect Remote Anti-Theft Personality (RAP) module Black 26-pin connector C246. Inspect RAP module connector for loose, damaged or corroded terminals. Repair as necessary. If connectors are okay, go to next step.
  2. Measure resistance of Light Blue/White wire between RAP module Black 26-pin connector C246 terminal No. 3 and Data Link Connector (DLC) 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, go to step  4.
  3. Connect RAP module connector. Perform data link diagnostic test. See DATA LINK DIAGNOSTIC TEST  under SELF-DIAGNOSTIC SYSTEM. If RAP module responds to NGS tester, system is functioning properly. If RAP module does not respond to NGS tester, replace RAP module. See REMOTE ANTI-THEFT PERSONALITY MODULE  under REMOVAL & INSTALLATION.
  4. Disconnect and inspect both halves of in-line Gray 16-pin connector C247 located behind left side of instrument panel. See Fig 2. Inspect connector for loose, damaged or corroded terminals. Repair as necessary. If connector is okay, go to next step.
  5. Measure resistance of Light Blue/White wire between RAP module Black 26-pin connector C246 terminal No. 3 and in-line 16-pin connector C247 (male half) terminal No. 16. See Fig 1 and Fig 3 . If resistance is less than 5 ohms, repair Light Blue/White wire between female half of in-line connector C247 and DLC. If resistance is 5 ohms or more, repair open in Light Blue/White wire between RAP module and male half of in-line connector C247.
