communication diagnosis between BCM and each local unit (LCU), and display the results on the CON-
SULT-ll screen.
NOTE:
Sleep is a power saving function when a vehicle is stationary (all BCM related electrical equipment: OFF,

Wake-Up Diagnosis
The wake-up diagnosis is carried out when BCM detects the wake-up signal from each local unit (LCU). When
the switch shown on the screen is operated as instructed, each local control unit (LCU) outputs the wake-up
signal. If BCM cannot detect a wake-up signal, it is judged malfunctioning. The malfunctioning local control
unit (LCU) is displayed on the screen.
NOTE:
If any unspecified switch is operated, “Switch data not match” is displayed as a malfunctioning system.

●
For a specific local control unit (LCU), either “PAST COMM DATA” or “PAST NO RESPONSE” may be displayed instead of the
above results. This is caused by the data record, so erase the records.
(The display only shows the incident records, they are not malfunctions caused during the diagnosis. One possible cause is that an
reproducible incident symptom occurred.)
●
Follow the steps below to erase the memory
