< FUNCTION DIAGNOSIS >
POWER CONSUMPTION CONTROL SYSTEM
Sleep condition
Wake-up operation
 BCM changes from the low power consumption mode to the CAN communication sleep mode when the any
of the BCM wake-up conditions is fulfilled. Only the control with BCM is activated.
 BCM transmits the sleep wake up signal (wake up) to each unit when any of the CAN wake-up conditions is
fulfilled. It changes from the low power consumption mode or the CAN communication sleep mode to the
normal mode.
 Each unit starts the transmission of CAN communication with the sleep wake up signal. In addition, the com-
bination meter transmits the wake up signal to BCM via CAN communication to report the CAN communica-
tion start.

The BCM records the following condition at the moment a particular DTC is detected.
 Vehicle Speed

 Vehicle Condition (BCM detected condition)
IGN Counter
IGN counter indicates the number of times that ignition switch is turned ON after DTC is detected.
 The number is 0 when a malfunction is detected now.
 The number increases like 1 → 2 → 3...38 → 39 after returning to the normal condition whenever ignition
switch OFF → ON.
 The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.
