Disconnect light failure sensor 12-pin harness connector located in trunk compartment. See Fig 1. Check for continuity or voltage between ground and specified terminals. See LIGHT FAILURE SENSOR CIRCUIT TEST table. If values are as specified, replace light failure sensor. If values are not as specified, check and repair wiring harness as necessary. See WIRING DIAGRAMS .
