DTC 41, 42, 45, 46, 51, 52, 55, 56, 63: (ABS Actuator Solenoid Valve Or Solenoid Valve Relay)

  1. Check ABS solenoid relay fusible link "f" (40-amp). Fusible link "f" is located in the fusible link and fuse box in the engine compartment. See Fig 1 and Fig 2 . If fusible link is okay, go to next step. If fusible link is blown, go to step  6 .
  2. Check fuse No. 31 (10-amp), located in passenger compartment fuse block. See Figure . If fuse is okay, go to next step. If fuse is blown, go to step  8 .
  3. Disconnect ABS actuator/control unit 31 pin harness connector. See Figure . Check terminals for damage or loose connection. If a problem is found, repair as necessary. Reconnect connector. Perform self-diagnostics again. See SELF-DIAGNOSTICS  . Check ABS warning light. If ABS warning lamp stays on, go to next step. If ABS warning lamp does not stay on, system is okay.
  4. Check ABS ground circuit. See ABS ACTUATOR/CONTROL UNIT GROUND  under PRELIMINARY CHECKS. If a problem is found, repair as necessary. If ground circuit is okay, go to next step.
  5. Disconnect ABS actuator/control unit 31 pin harness connector. Measure voltage between chassis ground and ABS actuator/control unit 31 pin harness connector terminal No. 18. See Figure . If battery voltage is present, replace ABS actuator/control unit. See ABS ACTUATOR/CONTROL UNIT  under REMOVAL & INSTALLATION. If battery voltage is not present, check for faulty circuit between ABS actuator/control unit and fusible link. Repair as necessary.
  6. Replace fusible link. Turn ignition on and observe fusible link. If fusible link blows, go to next step. If fusible link does not blow, system is okay.
  7. Turn ignition Off. Disconnect ABS actuator/control unit 31 pin harness connector. Check continuity between chassis ground and ABS actuator/control unit 31 pin harness connector terminal 18. If continuity exists, replace ABS actuator/control unit. If continuity does not exist, check harness connector for open or short between ABS actuator/control unit and fusible link. Repair as necessary.
  8. Replace fuse. Turn ignition on and observe fuse. If fuse does not blow, system is okay. If fuse blows, check for short in circuit between ABS actuator/control unit and fuse. If a problem exist, repair as necessary. Perform self-diagnostics again. See SELF-DIAGNOSTICS  .
