Code 6-1, Front Fail-Safe Relay Circuit
- Remove and test front fail-safe relay and ABS fuses. 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.
- With front fail-safe relay removed, turn ignition switch to ON position. Using DVOM, check for voltage between Black/Yellow wire of fail-safe relay and ground. If battery voltage is not present, repair open in Black/Yellow wire.
- If battery voltage is present, turn ignition switch to OFF position. Check for continuity between Brown/Black wire of fail-safe relay and ground. If continuity exists, repair short in Brown/Black wire.
- Reinstall front fail-safe relay. Check for continuity between ground and Brown/Black and Brown/Blue solenoid terminals. If continuity exists, replace shorted solenoid.
- If continuity does not exist, disconnect 18-pin and 12-pin connectors from control unit. Check continuity from ground to Red/Black, Yellow/Black, Red/Blue and Yellow/Blue wires. If any wire shows continuity, repair short between solenoid and control unit.
- If continuity does not exist, check for continuity between terminal No. 17 (Yellow/Green wire) and ground. If continuity exists, repair short in Yellow/Green wire between control unit and front fail-safe relay.
- If continuity does not exist, remove rear fail-safe relay and turn ignition switch to ON position. Check for voltage between control unit connector terminal No. 17 (Yellow/Green wire) and ground. If battery voltage is not present, repair open in Yellow/Green wire between fail-safe relay and control unit.
- If battery voltage exists, check for loose control unit connectors. If necessary, substitute a known-good control unit and retest.
