Hazard warning switch circuit

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.

1. 1
   Perform active test by intelligent tester
2. 2
   Connect the intelligent tester (with can vim) to the dlc3.
3. 3
   Turn the ignition switch on and press the intelligent tester main switch on.
4. 4
   Select the item below in the active test and then check the relay operation.

   

1. 1
   Inspect fuse (haz)
2. 2
   Remove the haz fuse from the engine room no. 1 Relay block.
3. 3
   Measure the resistance of the fuse.

Standard resistance: below 1

3. Check wire harness (turn signal flasher relay - battery)

1. 1
   Remove the turn signal flasher relay from the instrument panel junction block.
2. 2
   Measure the voltage of the wire harness side connector.

Standard voltage

1. 1
   Check operation of turn signal flasher relay (marking: flsh)
2. 2
   Replace the turn signal flasher relay with a normally functioning one or a new one.
3. 3
   Check that the appropriate turn signal light flashes.
4. 4
   Connect the intelligent tester (with can vim) to the dlc3.
5. 5
   Turn the ignition switch on and press the intelligent tester main switch on.
6. 6
   Select the item below in the active test and then check the relay operation.

   

5. Inspect hazard warning signal switch

1. 1
   Remove the hazard warning signal switch.
2. 2
   Measure the resistance of the switch.

Standard resistance
