What it means
A control module has detected that the software in multi-axis acceleration sensor module A is incompatible with its own software or configuration. Stability or related functions may be affected; the specific effects depend on the vehicle.
How it works
Multi-axis acceleration sensor module A measures vehicle movement in multiple directions for systems such as stability control. This code sets when another module finds module A’s software or configuration incompatible with its own, which can limit stability-related functions or trigger warnings.
Common causes
Most likely first.
- Incorrect or incompatible multi-axis acceleration sensor module software
- Module replacement without required programming or configuration
- Incorrect module part number
Symptoms
- Multiple warning lights may illuminate
- Affected modules may go into limp mode or shut down
- Specific functions inoperative depending on module
- Diagnostic tools may show communication faults
How to diagnose it
- Scan the stability-control and other modules, saving freeze-frame data and related communication or configuration codes.
- Check whether the issue began after module A replacement, collision repair, or programming work.
- Read module A’s identity and software version and compare them with vehicle-specific service information.
- Inspect the module’s mounting and accessible connectors and wiring for damage, corrosion, or looseness.
- Verify module A’s orientation, configuration, and software compatibility using the manufacturer’s procedure.
Common fixes
- Repair a loose or corroded module A connection.
- Correct module A’s mounting or configuration if it does not match the vehicle setup.
- Program compatible software into the multi-axis acceleration sensor module.
- Replace an incorrect-part-number module A with the compatible unit and complete required setup.
Can I keep driving?
If stability-control warnings are on, drive cautiously and avoid high speeds, slippery surfaces, and abrupt maneuvers because stability assistance may be reduced. Stop if handling changes unexpectedly or braking and stability warnings indicate a more serious fault.
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.
