U1001 CAN COMM CIRCUIT
Description
INFOID:0000000009619956
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 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.

Component Inspection
INFOID:0000000009267061
1.
CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-I
1. Turn ignition switch OFF.
2. Disconnect intake valve timing control solenoid valve harness connector.
3. Check resistance between intake valve timing control solenoid valve terminals as follows.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Replace intake valve timing control solenoid valve. Refer to
.
2.
CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-II
1. Remove intake valve timing control solenoid valve. Refer to
2. Apply 12 V between intake valve timing control solenoid valve
terminals 1 and 2, and then interrupt it. Make sure that the
plunger moves as shown in the figure.
CAUTION:
Do not apply 12 V continuously for 5 seconds or more.
Doing so may result in damage to the coil in intake valve
timing control solenoid valve.
