DTC CONFIRMATION PROCEDURE
1.CHECK SELF-DIAGNOSIS RESULTS
Check the self-diagnosis results.
Is above displayed on the self-diagnosis display?
YES >> Proceed to diagnosis procedure. Refer to STC-19, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000001697730
1.CHECK DTC WITH ECM
Perform self-diagnosis for ECM. Refer to EC-107, "
CONSULT-III Function" (HR16DE with EURO-OBD), EC-
462, "CONSULT-III Function" (HR16DE without EURO-OBD), EC-772, "CONSULT-III Function" (MR18DE),
EC-1104, "
Diagnosis Description" (K9K).
Is any malfunction detected by self-diagnosis?
YES >> Check the malfunctioning system.
NO >> GO TO 2.
2.CHECK EPS CONTROL UNIT
Check EPS control unit input/output signal. Refer to STC-22, "
EPS Control Unit Input/Output Signal Reference
Va l u e".
OK or NG
OK >> GO TO 3.
NG >> Check EPS control unit pin terminals for damage or loose connection with harness connector. If
any items are damaged, repair or replace damaged parts.
3.CHECK DTC
Perform the self-diagnosis, after driving a vehicle for a while.
OK or NG
OK >>INSPECTION END
NG >> Perform self-diagnosis for ECM. Refer to EC-107, "
CONSULT-III Function" (HR16DE with EURO-
OBD), EC-462, "

U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000001716748
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.
