  • engine light coming on

    hi there guys

    I have an 05 v6 prado that has the engine light coming on intermittently

    I have had it on the scanner and it come up with

    P0504 - Brake switch electrical circuit interrelationship

    p0571 - Cruise control brake circuit

    after a bit of research i found that these codes are related to the brake switch that I have since replaced the brake switch

    now the light still coming on with no codes showing on the scanner .

    the engine light comes on after when i use the central and that fails to unlock the car ( indicator only flashes once and very fast ) I then repress the remote and it unlocks when i start the car the eng light is on and remains on for any period of time

    Now when the light decides to go off the car dies looses power but doesnt stall for aprox 3-5 seconds ( like it is going into limp mode )

    any ideas as to what it could be would be greatly appreciated

    Thanks in advance

    Did you try disconnecting the battery for hour or so might reset things

        Have you tried a different code reader? Not all readers read everything.

          I don't know if its a mith or not but have read on this forum.
          Somebody clearing codes then disconnecting the earth lead first then the positive then touching the two together to reset the ECU.
          Any futher comments on this would be appreciated.
          Cheers Troy

            Sounds like a myth.
