C1942
Malfunction In Signal From Steering Sensor To Front Active Stabilizer Control ECU
C1942 is an OBD-II diagnostic trouble code meaning: Malfunction In Signal From Steering Sensor To Front Active Stabilizer Control ECU. Common causes: malfunction of the steering angle sensor, broken or broken contact in the can bus between the sensor and the stabilizer ecu. Estimated repair cost: $56–333.
Symptoms
- The suspension or ESP fault indicator on the instrument panel is on
- Active anti-roll bar disabled
- Increased body roll in corners
- Deterioration of stability during dynamic driving
- Possible concomitant deactivation of the stabilization system (ESP/VSC)
Causes
- Malfunction of the steering angle sensor
- Broken or broken contact in the CAN bus between the sensor and the stabilizer ECU
- Steering angle sensor calibration error after wheel alignment
- Front active stabilizer control unit malfunction
- Problems with power supply or grounding of the sensor
How to Fix
- Read all fault codes with a scanner, pay attention to the steering sensor and CAN bus codes
- Check steering angle sensor calibration (often resets after wheel alignment)
- Perform the rotation angle sensor initialization/calibration procedure via scanner
- Check the integrity of the CAN bus and sensor connectors
- Inspect the rotation angle sensor for mechanical damage
- If the sensor is faulty - replace and calibrate, reset codes
