Inspection Procedure

WARNING: This page is about a different car, the 2002 Toyota MR2. However, it is still accessible from the selected car via links, so may be relevant.
  1. Delete DTC and insert all presently available keys to check whether engine starts or not. 
    NOTE: When inserting the key that does not start the engine, DTC B2795/99 is stored in memory.

    RESULT: 

    1. OK: All keys start engine. No problem.
      NOTE: If the result is "OK", please confirm whether or not customers have ever inserted the unregistered key or the immobilizer key (with transponder chip) of other vehicle in the ignition key cylinder, and find out the cause of detecting DTC.
    2. NG: A specific key does not start engine. Go to next step.

  2. Register key that does not start engine.
