Power Supply Circuit Inspection
INFOID:0000000001704663
1.CHECK FUSE
Check that the following fuses of the subwoofer (premium system) and audio unit are not blown.
OK or NG
OK >> GO TO 2.
NG >> If fuse is blown, be sure to eliminate cause of blown fuse before installing new fuse. Refer to PG-
3 .
2.AUDIO UNIT POWER SUPPLY CIRCUIT CHECK
1. Disconnect audio unit connector.
2. Check voltage between the audio unit and ground.
OK or NG
OK >> With premium system, GO TO 3.
NG >> • Check connector housings for disconnected or loose
terminals.
• Repair harness or connector.
3.SUBWOOFER (PREMIUM SYSTEM) POWER SUPPLY CIRCUIT CHECK
1. Disconnect subwoofer connector.
Occurrence condition Possible cause
Occurs only when engine is ON.A continuous growling noise occurs. The speed of
the noise varies with changes in the engine speed.Ignition components
A whistling noise occurs while the engine speed is
high. A booming noise occurs while the engine is
running and the lighting switch is ON.Generator
Noise only occurs when various
electrical components are oper-
ating.A cracking or snapping sound occurs with the op-
eration of various switches.Relay malfunction, radio malfunction
The noise occurs when various motors are operat-
ing.• Motor case ground
• Motor
The noise occurs constantly, not just under certain conditions.• Rear defogger coil malfunction
• Open circuit in printed heater
A cracking or snapping sound occurs while the vehicle is being driven, especially when
it is vibrating excessively.• Ground wire of body parts.
• Ground due to improper part installation
• Wiring connections or a short circuit

< SERVICE INFORMATION >
BCM (BODY CONTROL MODULE)
NOTE:
Headlamp has a dual system switch.
4. Example operation: (When lighting switch 1st position is turned ON)
• When lighting switch 1st position is turned ON, contact in combination switch turns ON. At this time if
OUTPUT 4 transistor is activated, BCM detects that voltage changes in INPUT 5.
• When OUTPUT 4 transistor is ON, BCM detects that voltage changes in INPUT 5, and judges lighting
switch 1st position is ON. Then BCM sends tail lamp ON signal to IPDM E/R using CAN communication.
• When OUTPUT 4 transistor is activated again, BCM detects that voltage changes in INPUT 5 and rec-
ognizes that lighting switch 1st position is continuously ON.
NOTE:
Each OUTPUT terminal transistor is activated at 10ms intervals. Therefore, after a switch is turned ON,
electrical loads are activated with a time delay. But this time delay is so short that it cannot be noticed.
5. Operation mode
• Combination switch reading function has operation modes as follows:
SKIB7614E
SKIB7615E

Normal status
• When BCM is not in sleep status, OUTPUT terminals (1-5) each turn ON-OFF every 10ms.
Sleep status
• When BCM is in sleep mode, transistors of OUTPUT 1 and 5 stop the output, and BCM enters low-cur-
rent-consumption mode. OUTPUTS (2, 3, and 4) turn ON-OFF at 60ms intervals, and receives lighting
switch input only.
CAN COMMUNICATION CONTROL
CAN communication allows a high rate of information through the two communication lines (CAN-L, CAN-H)
connecting the various control units in the system. Each control unit transmits/receives data, but selectively
reads required data only.
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 and combination meter 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 and combination meter.
• Two seconds after CAN communication of all control units stops, CAN communication switches to inac-
tive 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.
• Three seconds after CAN communication of all control units stops, CAN communication switches to
inactive status.
4. Sleep status
• BCM is activated with low current consumption mode.
• CAN communication is not active.

BCM (BODY CONTROL MODULE)
• 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
- Key switch (without Intelligent Key)
- Key switch and ignition knob switch (with Intelligent Key)
- Hazard switch
- Door lock/unlock switch
- Front door switch (LH, RH)
- Rear door switch (LH, RH)
- Back door lock assembly (Hatchback)
- Trunk key cylinder switch (Sedan)
- Trunk lamp switch and trunk release solenoid (Sedan)
- Combination switch (passing, lighting switch 1st position, front fog lamp)
- Keyfob (lock/unlock signal)
- Front door key cylinder switch LH
• 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.
