DTC CONFIRMATION PROCEDURE
1.CHECK SELF DIAGNOSTIC RESULT
With CONSULT
Turn ignition switch ON.
Perform self diagnostic result.
Is DTC C1143 detected? YES >> Proceed to diagnosis procedure. Refer to BRC-80, "Diagnosis Procedure".
NO >> Inspection End.
Diagnosis Procedure
Regarding Wiring Diagram information, refer to BRC-44, "Wiring Diagram".
1.CONNECTOR INSPECTION
Turn ignition switch OFF.
Disconnect ABS actuator and electric unit (control unit) and steering angle sensor connectors.
Check connectors and terminals for deformation, disconnection, looseness or damage.
Is the inspection result normal? YES >> GO TO 2.
NO >> Repair or replace as necessary.
2.CHECK STEERING ANGLE SENSOR MOUNTING CONDITION
Check steering angle sensor mounting condition.
Is the inspection result normal? YES >> GO TO 3.
NO >> Repair or replace malfunctioning components.
3.Check steering angle sensor power supply
Turn ignition switch OFF.
Disconnect steering angle sensor connector.
Turn ignition switch ON.
Check voltage between steering angle sensor connector M14 terminal 4 and ground.
Is the inspection result normal? Yes >> go to 4.
No >> check the following:
Repair or replace harness.
Fuse
4.Check steering angle sensor ground circuit
Turn ignition switch off.
Check continuity between steering angle sensor connector m14 terminal 1 and ground.
Is the inspection result normal? Yes >> go to 5.
No >> repair or replace malfunctioning components.
5.Check can communication line
Check “strg branch line circuit”. Refer to lan-66, "diagnosis procedure" (type 1) or lan-79, "diagnosis procedure" (type 2).
Is the inspection result normal? Yes >> replace abs actuator and electric unit (control unit). Refer to brc-110, "removal and installation".
No >> repair or replace malfunctioning components.
