## Interlock System - Key Interlock System Circuit Troubleshooting

SRS components are located in this area. Review the SRS component locations, and precautions and procedures in the SRS section before performing repairs or service.

1. | Measure the voltage between gauge assembly connector terminal B7 and body ground. Is there voltage? YES - Go to 2. NO - Repair open or short in the wire between gauge assembly connector and the under-dash fuse/relay box.n

2. | Connect key switch connector.

3. | Measure the voltage between gauge assembly connector terminal B2 and body ground. Is there battery voltage? YES - Go to 4. NO - Repair open or short in the wire between the key interlock solenoid connector and gauge assembly connector.n

4. | Disconnect gauge assembly connector A (20P).

5. | Check for continuity between gauge assembly connector terminal A17 and body ground while you move the shift lever in and out of [P] position. Is there continuity with the shift lever in [P] position, and no continuity with the shift lever out of [P]? YES - Faulty key interlock system circuit in the gauge assembly, replace the gauge assembly.n NO - Repair short in the park pin switch wire between gauge assembly connector terminal A17. If the park pin switch is faulty, replace it.n
