What does it mean?
C1282 is a Chassis (ABS, traction control, steering) fault code. It indicates: G Sensor (Lateral-G) In SAS Control Module Is Signal Error .
Symptoms
- Stability and traction lamps on, ESP inhibited
- Lateral G value in live data stuck, drifting or offset while the vehicle is stationary
- Unwanted brake intervention or none at all during cornering
- ABS lamp often lit as well
- Fault frequently returns after clearing without any road test
Likely causes
- Internal failure of the lateral G element built into the steering angle sensor control module
- Calibration lost after a battery disconnection or module replacement
- Loose module mounting so vibration corrupts the lateral signal
- Weak module supply or a high-resistance ground
- Corroded connector or chafed harness at the module
- Corrupted CAN messages between the module and the stability control unit
- Water damage or impact damage at the module location
How to fix it
- Read the lateral G value with the vehicle level and stationary; it should be at or very near zero
- Check that the module is bolted down securely and sits in its original orientation
- Inspect the connector and surrounding area for moisture and corrosion
- Measure supply voltage and ground quality at the module
- Check the CAN circuits for resistance and communication errors
- Run the zero point and steering angle calibration in the sequence the manufacturer specifies
- Replace and calibrate the module if the internal sensor remains faulty
