On-Vehicle Inspection

WARNING: This page is about a different car, the 2008 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
  1. INSPECT TURN SIGNAL FLASHER CIRCUIT 
    1. Check the power source circuit and ground circuit.
      1. Remove the turn signal flasher relay from the instrument panel junction block.
      2. Measure the voltage and resistance of the instrument panel junction block.

        Standard voltage 

        STANDARD VOLTAGE

        Tester Connection Condition Specified Condition
        Instrument panel junction block turn signal flasher relay terminal 1 (IG) - Body ground Ignition switch OFF Below 1 V
        Instrument panel junction block turn signal flasher relay terminal 1 (IG) - Body ground Ignition switch ON 10 to 14 V
        Instrument panel junction block turn signal flasher relay terminal 4 (+B) - Body ground Always 10 to 14 V

        IS-12 (ER) - Body ground Turn signal switch (right turn) OFF → ON 10 to 14 V → 0 V
        IS-13 (LL) - Body ground Hazard warning switch OFF → ON 0 V → 10 to 14 V (60 to 120 times per minute)
        IS-13 (LL) - Body ground Turn signal switch (left turn) OFF → ON 0 V → 10 to 14 V (60 to 120 times per minute)
        IS-16 (LR) - Body ground Hazard warning switch OFF → ON 0 V → 10 to 14 V (60 to 120 times per minute)
        IS-16 (LR) - Body ground Turn signal switch (right turn) OFF → ON 0 V → 10 to 14 V (60 to 120 times per minute)
        IS-17 (EHW) - Body ground Hazard warning switch OFF → ON 10 to 14 V → 0 V

        If the result is not as specified, replace the turn signal flasher relay.
