Circuit Fuse
Turn ignition switch to OFF position. Ensure DOME and DOOR fuses are okay. If fuses are okay, go to POWER SOURCE CIRCUIT. Replace fuse(s) if needed. If fuse(s) fails again, check for short in circuit between fuse(s) and ECU connector "B" terminal No. 11 (Red wire) and/or ECU connector T3 terminal No. 1 (Red wire). See Figure. Repair short in harness or connectors as necessary. See WIRING DIAGRAMS .
