Inspection Procedure

WARNING: This page is about a different car, the 2002 Toyota Sequoia. However, it is still accessible from the selected car via links, so may be relevant.
    NOTE: When inserting the key that does not start the engine, DTC (B 2795) is stored in memory.
    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.
