Toyota RAV4 Service Manual: Turn signal light circuit

Description

The turn signal flasher relay (marking: flsh) in the main body ecu turns on when it receives signals from the headlight dimmer switch integrated with the turn signal switch, causing the turn signal lights to flash.

Inspection procedure

  1. Check operation of turn signal light

  1. When the turn signal light switch is operated, check that the appropriate turn signal light flashes.

Toyota RAV4. Check operation of turn signal light




  1. Inspect fuse (ecu-ig2, haz)

  1. Remove the ecu-ig2 fuse from the instrument panel junction block.
  2. Remove the haz fuse from the engine room no. 1 Relay block.
  3. Measure the resistance of the fuses.

Standard resistance: below 1




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

Repair or replace harness and connector (front turn signal light - body ground)

  1. Inspect rear turn signal light

Toyota RAV4. Inspect rear turn signal light


  1. Remove the rear combinationl light.
  2. Connect the positive (+) lead from the battery to terminal 5 and the negative (-) lead to terminal 1, then check that the light comes on.

Ok: light comes on.



  1. Check wire harness (instrument panel junction block - rear turn signal light)
