Code 6-1, Front Fail-Safe Relay

  1. Start engine. If ANTI-LOCK light does not go off, go to next step. If light goes off, system is okay at this time. Check for damaged wire harness between control unit, solenoids and front fail-safe relay.
  2. Check for ABS trouble codes. If Code 6-1 is not set, perform appropriate trouble code test. If Code 6-1 is set, test front fail-safe relay and replace if necessary. See RELAY TEST under DIAGNOSIS & TESTING. Disconnect modulator 14-pin connector.
  3. Visually check modulator wire harness for short to power and repair or replace as necessary. If wire harness is okay, start engine. Measure voltage between Brown/Black wire terminal of front fail-safe relay connector and ground.
  4. If battery voltage is not present, go to next step. If battery voltage is present, Brown/Black wire between front fail-safe relay and modulator is shorted to power.
  5. Stop engine. Disconnect control unit 26-pin connector. Start engine. Measure voltage between Red/Black wire terminal of 26-pin connector and ground. If battery voltage is not present, go to next step. If battery voltage is present, Red/Black wire between control unit and modulator is shorted to power.
  6. Measure voltage between Red/Blue wire terminal of 26-pin connector and ground. If battery voltage is not present, go to next step. If battery voltage is present, Red/Blue wire between control unit and modulator is shorted to power.
  7. Measure voltage between Yellow/Black wire terminal of 26-pin connector and ground. If battery voltage is not present, go to next step. If battery voltage is present, Yellow/Black wire between control unit and modulator is shorted to power.
  8. Measure voltage between Yellow/Blue wire terminal of 26-pin connector and ground. If battery voltage is present, Yellow/Blue wire between control unit and modulator is shorted to power. If battery voltage is not present, check for loose control unit connectors. If connectors are okay, install known-good control unit and retest.
