Hazard Warning Light Function Inoperative
- Check Hazard Indicator Operation
Turn ignition off. Disconnect Smart Entrance Control Unit (SECU) harness connector. Using a fused jumper wire, connect Orange wire of terminal No. 7 (with anti-theft system) or terminal No. 14 (without anti-theft system) at SECU harness connector to ground. See WIRING DIAGRAMS
. If hazard warning lights illuminate, replace SECU. If hazard warning lights do not illuminate, check multi-remote control relay. Replace if necessary. If relay is okay, go to next step.
- Check Multi-Remote Control Relay Power Supply
Disconnect multi-remote control relay. Using DVOM, measure voltage between ground and terminal No. 1 (Green/Orange wire) at multi-remote control relay connector. If battery voltage is present, go to next step. If battery voltage is not present, check fuse No. 20 (10-amp), located in fuse block. Check for open or short in wiring harness between multi-remote control relay and fuse. Repair as necessary.
- Check Multi-Remote Control Relay Circuit
Using DVOM, measure voltage between terminals No. 3 (Green/Orange wire) and No. 5 (Green/Black wire) at multi-remote control relay connector. Battery voltage should be present. Measure voltage between terminals No. 6 (Green/Orange wire) and No. 7 (Green/Yellow wire) at multi-remote control relay connector. Battery voltage should be present. If voltage is as specified, recheck system. If battery voltage is not as specified, check wiring harness for open or short.
