Dark current reduction function

•  When a certain period of time elapses after the ignition is switched OFF, the body control module (BCM) cuts off the power supply input circuit of the CAN communication and the body control module (BCM) and reduces dark current to prevent battery discharge.
•  When the dark current reduction function is operated, the body control module (BCM) sends the following requests.
―  Auxiliary device power charging request (See AUXILIARY DEVICE POWER CHARGING SYSTEM.)
―  Screen display request (See MULTI-INFORMATION DISPLAY [(E)].)
―  Warning sound activation request (See NOTIFICATION AND WARNING SPEAKER [(E)].)


Structure/Construction

•  The body control module (BCM) is located on the inside of the front side trim (LH).
