NOTE: Before disconnecting or connecting any module, ensure ignition switch is in OFF position.
  1. Turn ignition off. Disconnect 40-pin ABS module connector located at left side of engine compartment. Inspect connector for physical damage, bent terminals or corrosion. Repair or replace connector as necessary and retest system. If connector is okay, go to next step.
  2. Measure resistance of Light Blue/White wire between ABS module connector and Data Link Connector (DLC). If resistance is less than 5 ohms, replace ABS module and retest system. If resistance is more than 5 ohms, go to next step.
  3. Disconnect and inspect both halves of 40-pin bulkhead connector located at left rear of engine compartment. Inspect connector for physical damage, bent terminals or corrosion. Repair or replace connector as necessary and retest system. If connector is okay, go to next step.
  4. Measure resistance of Light Blue/White wire between ABS module connector and male half of bulkhead connector. If resistance is less than 5 ohms, repair open in Light Blue/White wire between bulkhead connector and DLC and retest system. If resistance is more than 5 ohms, repair open in Light Blue/White wire between ABS module connector and bulkhead connector C148 and retest system.
