  1. Unplug service connector. See Figure. Connect jumper wire between DLC1 terminals Tc and E1. See Figure. Turn ignition on. If ABS light flashes 2 times per second, go to next step. If ABS light does not flash 2 times per second, refer to DTC DEFINITIONS  under DIAGNOSIS & TESTING.
  2. Inspect all speed sensors for proper installation. Repair as necessary. Clean all foreign material and metal chips from speed sensor tip.
  3. Enter speed sensor diagnostics. See SPEED SENSOR DIAGNOSTICS under DIAGNOSIS & TESTING . If speed sensor signal level is okay, go to next step. If speed sensor signal level is not okay, inspect sensor and sensor rotor. Replace as necessary.
  4. Turn ignition off. Unplug ABS ECU connector. Ensure continuity exists between each speed sensor connector and ABS ECU connector. If continuity readings change when wiring harness is twisted or moved, repair defective wiring harness between speed sensor and ABS ECU. If okay, go to next step.
  5. Check actuator operation. See ACTUATOR CHECK  under DIAGNOSIS & TESTING . If actuator operation is okay, replace ABS ECU. Retest system. See ABS ECU under REMOVAL & INSTALLATION . If actuator operation is not as specified, replace defective actuator.
