COMPONENT DIAGNOSIS
U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000003765661
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, 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, CAN-L) allowing a high rate of information transmission with less wiring. Each
control unit transmits/receives data but selectively reads required data only.

CAN Communication Signal Chart".

Diagnosis ProcedureINFOID:0000000003901175
1.CHECK DISPLAY UNIT POWER SUPPLY AND GROUND CIRCUIT
Check display unit power supply and ground circuit. Refer to AV-236, "
DISPLAY UNIT : Diagnosis Procedure".
Is inspection result normal?
YES >> GO TO 2.
NO >> Repair malfunctioning parts.
2.CHECK CONTINUITY COMMUNICATION CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect display unit connector and AV control unit connector.
3. Check continuity between display unit harness connector and AV control unit harness connector.
4. Check continuity between display unit harness connector and ground.
Is inspection result normal?
YES >> GO TO 3.
NO >> Repair harness or connector.
Part name Description
DISPLAY UNIT Display image is controlled by the serial communication from AV control unit.
 It receives the power (signal VCC and inverter VCC) from the AV control unit
and operates.
 RGB image signal is input from AV control unit (RGB, RGB area and RGB syn-
chronizing).
 Composite image (DVD, AUX and camera images) signal is input from AV con-
trol unit.
 Synchronize signal (HP, VP) is output to AV control unit.
