3. When displaying rear view image, check voltage between rear
view camera control unit harness connector B36 terminal 8 and
ground.
OK or NG
OK >> GO TO 7.
NG >> Replace rear view camera control unit.
7. CHECK REAR VIEW IMAGE SIGNAL
When displaying rear view image, check voltage waveform between
rear view camera control unit harness connector B36 terminal 10
and ground with CONSULT-ll or oscilloscope.
OK or NG
OK >> GO TO 8.
NG >> Replace rear view camera.2 – Ground : Continuity should exist.

BCM (BODY CONTROL MODULE)

Operation Mode
Combination switch reading function has operation modes shown below.
1. Normal status
When BCM is not in sleep status, OUTPUT terminals (1-5) send out ON signal every 10 ms.
2. Sleep status
When BCM is in sleep status, transistors of OUTPUT 1 stop the output, and BCM enters low power mode.
OUTPUT 2- 5 send out ON signal every 60 ms, and accept only input from lighting switch (except turn sig-
nal switch) system.

BCM STATUS CONTROL
BCM changes its status depending on the operation status in order to save power consumption.
1. CAN communication status

With ignition switch ON, CAN communicates with other control units normally.

Control by BCM is being operated properly.

When ignition switch is OFF, switching to sleep mode is possible.

Even when ignition switch is OFF, if CAN communication with IPDM E/R, Intelligent Key unit or unified
meter and A/C amp. is active, CAN communication status is active.
2. Sleep transient status

This status shuts down CAN communication when ignition switch is turned OFF.

It transmits sleep request signal to IPDM E/R, Intelligent Key unit, driver seat control unit and unified
meter and A/C amp.

2 seconds after CAN communication of all control units stops, sleep transient status switches to CAN
communication inactive status.
3. CAN communication inactive status

With ignition switch OFF, CAN communication is not active.

With ignition switch OFF, control performed only by BCM is active.

When all controls that BCM performs stop, CAN communication inactive status switches to sleep sta-
tus.
4. Sleep status

BCM is activated with low power mode.

CAN communication is not active.

When CAN communication operation is detected, it switches to CAN communication status.

When a state of the following switches changes, it switches to CAN communication state.
–Ignition switch (ACC, ON)
–Key switch
–Ignition knob switch
–Hazard switch
–Door lock/unlock switch
–Front door switch (driver side, passenger side)
–Rear door switch (RH, LH)
–Trunk lid opener switch
–Trunk room lamp switch
–Combination switch (passing, lighting switch 1ST position, front fog lamp)
–Remote keyless entry receiver (lock/unlock signal)

When control performed only by BCM is required by switch, it shifts to CAN communication inactive
mode.

Status of combination switch reading function is changed.
