COMPONENT DIAGNOSIS
U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000003759094
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control unit, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with 2 communication lines (CAN H-line, CAN L-line) allowing a high rate of information transmission with less
wiring. Each control unit transmits/receives data but selectively reads required data only.

HIGH FLASHER OPERATION
BCM detects the turn signal lamp circuit status by the current value.
BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal
lamp operating.
NOTE:
The blinking speed is normal while activating the hazard warning lamp.

Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair harness or connector.
2.CHECK SPIRAL CABLE
Check spiral cable.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Replace spiral cable.
3.CHECK AUDIO UNIT VOLTAGE
1. Connect audio unit connector and spiral cable connector.
2. Turn ignition switch ON.
3. Check voltage between audio unit harness connector terminals.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Replace audio unit.
4.CHECK STEERING SWITCH
1. Turn ignition switch OFF.
2. Check steering switch. Refer to AV-21, "
Component Inspection".
Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace steering switch.
