Defect Code 10, 11, 12, 13

Defect Code 10, 11,12,13:

*D* Defect code memory: 10, 11, 12, 13 Steering angle signal

Explanation: This defect code is stored when the steering angle signal received by the control unit is faulty.

Possible causes: Loose contact, contact corrosion, steering angle sensor installed in wrong position, short of sensor supply wire (5 Volt) to ground, sensor
defective.

Troubleshooting: Check installation position of steering angle sensor and correct if necessary; refer to Repair Instructions "EDC Ill".

If installation position is OK, check steering angle sensor and renew if necessary (Repair Instructions "EDC III").

If steering angle sensor is OK., measure voltage at connector X 945 Pin 25 (voltage supply of steering angle sensor). Is a voltage of 5 Volt applied?

If no, check connections at the control unit (connection terminal 30; X 945 Pin 26).

If yes, check signal wire of steering angle sensor to the EDC control unit and repair if necessary; from connector X 945 Pins 14 and 15 to steering angle
sensor.

Is defect rectified?

If no, check ground connection of steering angle sensor and repair if necessary: From steering angle sensor to ground point.

Note: After defect has been repaired, perform steering angle offset (in diagnostic program) and check function of steering angle sensor in accordance with
screen display (test procedure).
