Test F: Anti-Lock Brake System (Abs) Module Does Not Respond To NGS Tester

  1. Turn ignition off. Disconnect ABS module connector located in right front of engine compartment, behind radiator. Inspect connector for loose, damaged or corroded terminals. Repair connector as necessary and retest system for normal operation. If connector is okay, go to next step.
  2. Measure resistance of Light Blue/White wire between terminal No. 24 at ABS module connector and terminal No. 7 at DLC. See Figure and Fig 1 . If resistance is less than 5 ohms, replace ABS module and retest system for normal operation. If resistance is 5 ohms or more, go to next step.
  3. Disconnect Black 16-pin connector C108 located near right side of radiator. Inspect connector for loose, damaged or corroded terminals. Repair connector as necessary and retest system for normal operation. If connector is okay, go to next step.
  4. Measure resistance of Light Blue/White wire between terminal No. 5 at male half of connector C108 and terminal No. 7 at DLC. See Figure and Fig 2 . If resistance is less than 5 ohms, repair open in Light Blue/White wire between male half of connector C108 and ABS module. Retest system for normal operation.
  5. Disconnect Gray 8-pin connector C259 located behind right kick panel. See Figure . Inspect connector for loose, damaged or corroded terminals. Repair connector as necessary and retest system for normal operation. If connector is okay, go to next step.
  6. Measure resistance of Light Blue/White wire between terminal No. 4 at female half of connector C259 and terminal No. 7 at DLC. If resistance is less than 5 ohms, repair open in Light Blue/White wire between female half of connector C108 and female half of connector C259. Retest system for normal operation. If resistance is 5 ohms or more, go to next step.
  7. Disconnect Black 14-pin connector C219 located behind right kick panel. See Figure . Inspect connector for loose, damaged or corroded terminals. Repair connector as necessary and retest system for normal operation. If connector is okay, go to next step.
  8. Measure resistance of Light Blue/White wire between terminal No. 14 at female half of connector C219 and terminal No. 7 at DLC. See Figure and Fig 3 . If resistance is less than 5 ohms, repair open in Light Blue/White wire between male half of connector C259 and male half of connector C219. Retest system for normal operation. If resistance is 5 ohms or more, repair open in Light Blue/White wire between female half of connector C219 and DLC. Retest system for normal operation.
