DescriptionINFOID:0000000005398288
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 s
peed 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 CA N 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.

Refer to EC-128, "
Component Inspection".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Replace intake valve timing control solenoid valve.
3.CHECK CRANKSHAFT POSITION SENSOR (POS)
Refer to EC-261, "
Component Inspection".
Is the inspection result normal?
YES >> GO TO 4.
NO >> Replace crankshaft position sensor (POS).
4.CHECK CAMSHAFT POSITI ON SENSOR (PHASE)
Refer to EC-266, "
Component Inspection".
Is the inspection result normal?
YES >> GO TO 5.
NO >> Replace camshaft position sensor (PHASE).
5.CHECK CAMSHAFT (INTAKE)
Check the following.
Selector lever 1st or 2nd position
