DTC CONFIRMATION PROCEDURE
1.CHECK SELF-DIAGNOSTIC RESULT
With CONSULT.
Is DTC C1143 detected? YES >> Proceed to diagnosis procedure. Refer to BRC-96, "Diagnosis Procedure".
NO >> Inspection End.
Diagnosis Procedure
Regarding Wiring Diagram information, refer to BRC-57, "Wiring Diagram".
1.CONNECTOR INSPECTION
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
Is the inspection result normal? YES >> GO TO 5.
NO >> GO TO 4.
4.CHECK STEERING ANGLE SENSOR POWER SUPPLY CIRCUIT
Is the inspection result normal? YES >> Perform trouble diagnosis for ignition power supply.
NO >> Repair or replace malfunctioning components.
5.CHECK STEERING ANGLE SENSOR GROUND CIRCUIT
Is the inspection result normal? YES >> GO TO 6.
NO >> Repair or replace malfunctioning components.
6.CHECK CAN COMMUNICATION LINE
Check “STRG BRANCH LINE CIRCUIT”. Refer to LAN-90, "Diagnosis Procedure" (Type 1) or LAN-111, "Diagnosis Procedure" (Type 2).
Is the inspection result normal? YES >> Replace ABS actuator and electric unit (control unit). Refer to BRC-136, "Removal and Installation".

Sensor power supply2 circuit
Description
ECM supplies a voltage of 5 V to some of the sensors systematically divided
into 2 groups, respectively.
Accordingly, when a short circuit develops in a sensor power source, a
malfunction may occur simultaneously
in the sensors belonging to the same group as the short-circuited ...
