Inspection Procedure

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. PERFORM ACTIVE TEST BY TECHSTREAM 
    1. Connect Techstream to the DLC3.
    2. Turn the ignition switch ON and turn Techstream ON.
    3. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the Fuel Pump / Speed
    4. Check the operation of the relay while operating it using Techstream.

      OK: 

      Operating noise can be heard from the relay. 

    OK: CHECK INTERMITTENT PROBLEMS 

    NG: Go to next step 

  2. INSPECT FUEL PUMP RELAY (Marking: F/PMP)

      Tester Connection Specified Condition
      3 - 4 Below 1 Ω
      3 - 5 10 kΩ or more
      3 - 4 10 kΩ or more (when battery voltage is applied to terminals 1 and 2)
      3 - 5 Below 1 Ω (when battery voltage is applied to terminals 1 and 2)

    NG: REPLACE FUEL PUMP RELAY (Marking: F/ PMP) 

    OK: Go to next step 

  3. CHECK WIRE HARNESS (F/PMP RELAY - ECM)
