Code 6-1, Front Fail-Safe Relay Circuit

  1. Remove and test front fail-safe relay. See RELAY TEST  under COMPONENT TESTS. Replace relay if it is defective. If relay is okay, disconnect 10-pin connector from solenoids. Connector is located on right side of engine compartment, near shock tower.
  2. Using DVOM, check for continuity between Brown/Black wire of fail-safe relay and ground. If no continuity exists, go to next step. If continuity exists, repair short in Brown/Black wire between solenoid and front fail-safe relay.
  3. Check for continuity at solenoid connector (solenoid side) between Brown/Black wire and ground and between Brown/Blue wire and ground. If no continuity exists, go to next step. If continuity exists, solenoid is defective.
  4. Disconnect 18-pin and 12-pin connectors from control unit. Check for continuity at 12-pin connector between ground and Red/Black, Yellow/Black, Red/Blue and Yellow/Blue wires. If continuity does not exist, go to next step. If continuity exists in any wire, repair short in wire having continuity between solenoid and control unit connector.
  5. Check for continuity at 18-pin connector between Yellow/Green wire and ground. If continuity exists, repair short in Yellow/Green wire control unit connector and front fail-safe relay. If no continuity exists, check for loose control unit connectors. If connectors are okay, install a known good control unit and retest.
