Toyota RAV4 (XA40) 2013-2018 Service Manual: Hazard warning switch circuit
Description
When the hazard warning signal switch is turned on, the turn signal flasher relay (marking: flsh) in the main body ecu turns on to flash the hazard warning signal lights.
Wiring diagram
Inspection procedure
- Perform active test by intelligent tester
- Connect the intelligent tester (with can vim) to the dlc3.
- Turn the ignition switch on and press the intelligent tester main switch on.
- Select the item below in the active test and then check the relay operation.
Ok: all hazard warning signal lights flash.
- Inspect fuse (haz)
- Remove the haz fuse from the engine room no. 1 Relay block.
- Measure the resistance of the fuse.
Standard resistance:
below 1
- Check wire harness (turn signal flasher relay - battery)
- Remove the turn signal flasher relay from the instrument panel junction block.
- Measure the voltage of the wire harness side connector.
Standard voltage
- Check operation of turn signal flasher relay (marking: flsh)
- Replace the turn signal flasher relay with a normally functioning one or a new one.
- Check that the appropriate turn signal light flashes.
- Connect the intelligent tester (with can vim) to the dlc3.
- Turn the ignition switch on and press the intelligent tester main switch on.
- Select the item below in the active test and then check the relay operation.
Ok: all hazard warning signal lights flash.
Replace turn signal flasher relay
- Inspect hazard warning signal switch
- Remove the hazard warning signal switch.
- Measure the resistance of the switch.
Standard resistance
Repair or replace harness and connector (hazard warning signal switch - body ground)
