Diagnosis Procedure

WARNING: This page is about a different car, the 2009 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK SEATBACK THERMAL ELECTRIC DEVICE

    Perform thermal electric device component inspection for the seatback. Refer to "COMPONENT INSPECTION (THERMAL ELECTRIC DEVICE) ".

    Is the inspection result normal? 

    YES: GO TO 2.

    NO: Replace seatback thermal electric device.

  2. CHECK SEATBACK THERMAL ELECTRIC DEVICE CIRCUITS
    1. Turn ignition switch OFF.
    2. Disconnect seatback thermal electric device connector and climate controlled seat control unit connector B217.
    3. Check continuity between seatback thermal electric device connector B218 (A) terminals 1, 2 and climate controlled seat control unit connector B217 (B) terminals 25, 28.
