DTC C1297/97 Steering Angle Sensor


DESCRIPTION

  1. The 4WD control ECU determines that the vehicle is turning based on the signals sent from the steering angle sensor.
  1. The steering angle sensor signal is sent to the 4WD control ECU via the CAN communication system.
  1. 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.

DTC No.

INSPECTION PROCEDURE

HINT:
Check the condition of each related circuit connector before troubleshooting (RAV4_ACA30 RM000000UZ306OX.html).
1.CHECK FOR DTC

  1. Clear the DTC (RAV4_ACA30 RM0000020BA00VX.html).

  1. Turn the ignition switch off.

  1. Turn the ignition switch on (IG) again and check that no CAN communication system DTC(s) is output.

  1. Start the engine.

  1. Drive the vehicle and turn the steering wheel to the right and left at a speed of 35 km/h (22 mph) and check that no brake control system (steering angle sensor) DTC (C1432,C1433 or C1434) is output (RAV4_ACA30 RM0000020BA00VX.html).


Result:

Result
Proceed to
Neither CAN communication system DTC nor brake control system DTC is output
A
CAN communication system DTC is output
B
Brake control system (steering angle sensor) DTC (C1432,C1433 or C1434) is output
C
HINT:
When DTCs indicating a CAN communication system malfunction are output, repair the CAN communication system before repairing each corresponding sensor.


B
REPAIR CIRCUIT INDICATOR OUTPUT CODE (CAN COMMUNICATION SYSTEM)

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


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

  1. Disconnect the E95 sensor connector.

  1. Measure the voltage of the wire harness side connector.

    Standard voltage:
    Tester Connection
    		Condition
    		Specified Condition
    E95-4 (IG) - Body ground
    		Ignition switch on (IG)
    		10 to 14 V
    E95-5 (BAT) - Body ground
    		Always
    		10 to 14 V


NG
REPAIR OR REPLACE HARNESS AND CONNECTOR
OK


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

  1. Disconnect the E95 sensor connector.

  1. Measure the resistance of the wire harness side connector.

    Standard resistance:
    Tester Connection
    		Condition
    		Specified Condition
    E95-1 (ESS) - Body ground
    		Always
    		Below 1 Ω
