If “DTC CONFIRMATION PROCEDURE” has been previously conducted, always turn ignition switch OFF and
wait at least 10 seconds before conducting the next test.
>> GO TO 2.
2.DTC REPRODUCTION PROCEDURE
With CONSULT
1. Turn the ignition switch ON.
2. Perform self diagnosis for “ABS”.
Is DTC
“U1002” detected?
YES >> Proceed to BRC-107, "Diagnosis Procedure".
NO >> Inspection End.
Diagnosis ProcedureINFOID:0000000009463822
CAUTION:
• Never apply 7.0 V or more to the measurement terminal.
• Use a tester with open terminal voltage of 7.0 V or less.
• Turn the ignition switch OFF and disconnect th e battery cable from the negative terminal when
checking the harness.
1.CHECK CAN DIAGNOSIS SUPPORT MONITOR
1. Select “ABS” and “CAN Diagnosis Support Monitor” in order with CONSULT.
2. Check malfunction history between each control unit c onnected to ABS actuator and electric unit (control
unit).
Check the result of
“PA S T”?
All items are “OK”>>Refer to GI-43, "Intermittent Incident".
“TRANSMIT DIAG” is other than “OK”>>GO TO 2.
A control unit other than ABS actuator and electric unit (control unit) is anything other than “OK”>>GO TO 3.
2.CHECK TRANSMITTING SIDE UNIT
Check the ABS actuator and electric unit (control unit) harness connector terminals 14 and 26 for damage or
loose connection.
Is the inspection result normal?
YES >> Erase self-diagnosis results. Then perform self-diagnosis for “ABS” with CONSULT.
NO >> Recheck terminals for damage or loose connection.
3.CHECK APPLICABLE CONTROL UNIT
Check damage or loose connection of each CAN communication line harness connector terminals.
Is the inspection result normal?
YES >> Erase self-diagnosis results. Then perform self-diagnosis for applicable control unit with CON-
SULT.
NO >> Recheck terminals for damage or loose connection.
DTC Display item Malfunction detected condition Possible cause
U1002 SYSTEM COMM(CAN) When ABS actuator and electric
unit (control unit) is not
transmitting or receiving CAN communication signal for 2
seconds or less. • CAN communication line
• ABS actuator and electric unit
(control unit)
