Check for continuity between the No. 8 terminal of the interlock control unit connector and the No. 5 terminal of the interlock relay (key lock solenoid) connector. Wire side of female terminals Is there continuity? YES - Go to step 27. NO - Repair open or short in the wire between the No. 8 terminal of the interlock control unit and the interlock relay (key lock solenoid). Check for continuity between the No. 2 terminal of the interlock relay (key lock solenoid) connector and body ground. INTERLOCK RELAY (KEY LOCK SOLENOID) CONNECTOR Wire side of female terminals Is there continuity? YES - Go to step 28. NO - Repair open in the wire between the No. 2 terminal of the interlock relay (key lock solenoid) connector and ground (G451), or repair poor ground (G451).

Turn the ignition switch ACC (ll). Measure the voltage between the No. 1 terminal of the interlock relay (key lock solenoid) connector and body ground. INTERLOCK RELAY (KEY LOCK SOLENOID) CONNECTOR Wire side of female terminals Is there voltage? YES - Repair open or short in position wire between the No. 3 terminal of the interlock relay (key lock solenoid) connector and the shift position switch.
