Hazard Warning Light Function Inoperative

  1. Check Hazard Indicator Operation

    Turn ignition off. Disconnect Smart Entrance Control Unit (SECU) harness connector. Using a fused jumper wire, connect terminal No. 7 (Orange wire) 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 No. 1. Replace if necessary. If relay is okay, go to next step.

  2. Check Multi-Remote Control Relay No. 1 Power Supply

    Disconnect multi-remote control relay No. 1. Using DVOM, measure voltage between ground and terminal No. 1 (Green/Orange wire) at multi-remote control relay No. 1 connector. See WIRING DIAGRAMS  . 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 No. 1 and fuse. Repair as necessary.

  3. Check Multi-Remote Control Relay No. 1 Circuit

    Using DVOM, measure voltage between terminals No. 3 (Green/Orange wire) and No. 5 (Green/Black wire) at multi-remote control relay No. 1 connector. See WIRING DIAGRAMS  . 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 No. 1 connector. Battery voltage should be present. If voltage is as specified, check multi-remote control relay No. 2. Replace if necessary. If voltage is not as specified, check wiring harness for open or short.
