Lost Communication With Steering Angle Sensor Module

What it means

The steering angle sensor tells stability control how far and which way the steering wheel is turned, and systems such as electric power steering and lane keeping also use it. This code sets when messages from this sensor stop reaching the network. The sensor usually sits on the steering column behind the wheel near the clock spring, and on some vehicles it is built into the power steering module.

Symptoms4

• Stability or traction control light on.
• Stability control no longer intervenes.
• Power steering light or changed steering effort on vehicles whose electric steering uses this sensor.
• Assist features such as lane keeping or cornering lights disabled on some vehicles.

Possible causes6

• Damaged or loose sensor connector on the steering column, especially after work on the steering wheel or airbag.
• Blown sensor power fuse.
• Weak battery or low voltage.
• Open or shorted CAN wiring to the sensor.
• Internal sensor failure.
• Failure of the power steering module or another unit when the sensor is built into it.

How to diagnose5

1. Read codes from all modules and check for related power steering or clock spring codes.
2. Try to read steering angle data with a scan tool; if nothing appears, check the sensor power and ground.
3. Inspect the sensor connector on the column; reaching it may require removing the column covers and possibly the airbag, which is work for a trained technician.
4. Measure power and ground at the connector and check the CAN lines against the manufacturer specification.
5. Make sure earlier steering wheel or alignment work did not leave the connector unplugged or the wire stretched.

How to fix5

1. Replace the blown fuse and charge or replace the battery.
2. Reconnect and clean the connector, and repair damaged wiring.
3. Replace the sensor if proven faulty.
4. Calibrate the steering angle sensor with a scan tool after any repair or wheel alignment.
5. Clear the codes, road test and confirm the stability light stays off.

Repair cost

In Saudi riyals; the highlighted part is the expected range for this fault.

The cost is low for an unplugged connector or a fuse, rises when the sensor is replaced and calibrated, and is higher when it is built into the clock spring or steering module.

Prices are rough estimates for common cars at independent workshops and vary with the car and the source of the part.
