What it means
The stability control module monitors inputs and operation of the electronic stability control system. It sets this code when it detects a system fault that does not identify a more specific component in the code title.
At a glance
- Usually lights the ABS or stability-control warning light
How it works
Electronic stability control compares wheel speeds, steering direction, and vehicle motion, then may brake individual wheels or reduce engine torque to help keep the vehicle on course. This general system code indicates a detected stability-control fault without naming a particular component, so related codes and module data are needed to narrow it down.
Common causes
Most likely first.
- Wheel speed, yaw rate, or steering angle sensor fault
- Damaged wiring or connector
- Low system voltage or poor ground
- Stability control module fault
Symptoms
- Stability-control warning light
- Stability control may be limited or disabled
How to diagnose it
- Scan the ABS/stability module for companion codes and freeze-frame data before clearing anything, since these may identify a wheel-speed, yaw-rate, or steering-angle fault.
- Check battery and charging-system condition and inspect the stability module's power, ground, and related fuse connections for looseness or corrosion.
- Inspect wheel-speed-sensor wiring at all wheels and the yaw-rate and steering-angle sensor connectors for damage or poor connections.
- Compare live wheel speeds and steering-angle, yaw-rate, and acceleration readings for implausible values under the conditions indicated by the stored data.
- Test the implicated sensors, wiring, and module communication according to the manufacturer's procedures before replacing the stability-control module.
Common fixes
- Clean and secure corroded or loose power, ground, or sensor connections.
- Repair damaged wiring to the sensor identified by companion codes or live data.
- Replace a confirmed faulty wheel-speed, yaw-rate, or steering-angle sensor.
- Repair or replace the stability-control module only after its power, grounds, inputs, and communication have been checked.
Can I keep driving?
The vehicle may have reduced or no stability assistance, although basic braking may still work. Drive cautiously, allow extra room, and avoid slippery roads or sudden manoeuvres until the fault is diagnosed.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
