U1000 CAN COMM CIRCUIT

U1000 CAN COMM CIRCUIT

Description

INFOID:0000000012199719

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.

DTC Logic

INFOID:0000000012199720

DTC DETECTION LOGIC

POSSIBLE CAUSE

NOTE:

Confirm if DTC is PAST or CRNT. If DTC is CRNT, proceed with Diagnosis Procedure. If DTC is PAST, clear

DTC. Do not replace the ABS actuator and electric unit (control unit) for a PAST DTC.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If “DTC CONFIRMATION PROCEDURE” has been previously conducted, always turn the ignition switch OFF

and wait at least 10 seconds before conducting the next test.

>> GO TO 2.

2.

CHECK DTC DETECTION

With CONSULT

1. Turn the ignition switch OFF.

NOTE:

Wait at least 10 seconds after turning ignition switch OFF.

2. Start the engine.

NOTE:

Wait at least 10 seconds after start the engine.

3. Perform self-diagnosis for “ABS”.
Is DTC “U1000” detected?

YES-1 >> “CRNT” is displayed: Proceed to 

BRC-126, "Diagnosis Procedure"

.

YES-2 >> “PAST” is displayed: INSPECTION END (Erase the memory of self-diagnosis results.)

NO-1 >> To check malfunction symptom before repair: Refer to 

GI-45, "Intermittent Incident"

.

NO-2 >> Confirmation after repair: INSPECTION END

Diagnosis Procedure

INFOID:0000000012199721
