Hazard Reminder Check

  1. Check Hazard Warning Lights

    Using hazard switch, ensure hazard warning lights flash. If hazard warning lights flash, go to next step. If hazard warning lights do not flash, check hazard warning light circuit. See appropriate wiring diagram in EXTERIOR LIGHTS article.

  2. Check Hazard Reminder Operation

    Turn ignition off. Disconnect Smart Entrance Control Unit (SECU) harness connector. Using a jumper wire, connect terminal No. 7 (Orange/Black wire) at SECU harness connector to ground. See WIRING DIAGRAMS  . If hazard warning lights illuminate, hazard reminder is okay. If hazard warning lights do not illuminate, go to next step.

  3. Check Multi-Remote Control Relay

    Check multi-remote control relay. See WIRING DIAGRAMS  . Replace if necessary. If relay is okay, go to next step.

  4. Check Multi-Remote Control Relay Power Supply

    Disconnect multi-remote control relay. Using DVOM, measure voltage between ground and terminal No. 1 (White/Green wire) at multi-remote control relay connector. See WIRING DIAGRAMS  . If battery voltage is present, go to next step. If battery voltage is not present, check fuse No. 5 (15-amp), located in fuse block. Check for open or short in wiring harness between multi-remote control relay and fuse. Repair as necessary.

  5. Check Multi-Remote Control Relay Circuit

    Using DVOM, measure voltage between terminals No. 3 (White/Green wire) and No. 5 (Green/Black wire) at multi-remote control relay connector. Battery voltage should be present. Measure voltage between terminals No. 6 (White/Green wire) and No. 7 (Green/Yellow wire) at multi-remote control relay connector. Battery voltage should be present. If voltage is as specified, check for open or short in wiring harness between multi-remote control relay and SECU. If voltage is not as specified, check for open or short in wiring harness between multi-remote control relay and fuse, or between multi-remote control relay and turn signal lights. Repair as necessary.
