C1297

DIFFERENTIAL: ACTIVE TORQUE CONTROL 4WD SYSTEM: C1297/97: Steering Angle Sensor
C1297/97 - Steering Angle Sensor

DESCRIPTION

* The 4WD control ECU determines that the vehicle is turning based on the signals sent from the steering angle sensor.

* The steering angle sensor signal is sent to the 4WD control ECU via the CAN communication system.

* The 4WD control ECU detects the amount of steering wheel movement and performs "slip control at vehicle start up", according to the amount of movement, and "slip control" to secure high turning performance.

INSPECTION PROCEDURE

HINT
Check the condition of each related circuit connector before troubleshooting Electronic Circuit Inspection Procedure.

PROCEDURE

1. CHECK FOR DTC

(a) Clear the DTC .

(b) Turn the ignition switch off.

(c) Turn the ignition switch ON again and check that no CAN communication system DTC(s) is output.

(d) Start the engine.

(e) Drive the vehicle and turn the steering wheel to the right and left at a speed of 35 km/h (24 mph) and check that no brake control system (steering angle sensor) DTC (C1432,C1433 or C1434) is output Vehicle Stability Control System.

Result:





HINT
When DTCs indicating a CAN communication system malfunction are output, repair the CAN communication system before repairing each corresponding sensor.

C -- REPAIR OR REPLACE CIRCUIT INDICATOR OUTPUT CODE (STEERING ANGLE SENSOR CIRCUIT)

B -- REPAIR CIRCUIT INDICATOR OUTPUT CODE (CAN COMMUNICATION SYSTEM)
A -- Continue to next step.

2. CHECK WIRE HARNESS (STEERING ANGLE SENSOR - BATTERY)

(a) Disconnect the E11 sensor connector.





(b) Measure the voltage of the wire harness side connector.

Standard voltage:





NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.

3. CHECK WIRE HARNESS (STEERING ANGLE SENSOR - BODY GROUND)

(a) Disconnect the E11 sensor connector.





(b) Measure the resistance of the wire harness side connector.

Standard resistance:





Result:





C -- REPAIR OR REPLACE HARNESS AND CONNECTOR

B -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE

A -- REPLACE STEERING ANGLE SENSOR
