Lost Communication With Multi-axis Acceleration Sensor Module
What it means
The multi-axis acceleration sensor module combines longitudinal and lateral acceleration and yaw rate measurement in one part, feeding stability control and sometimes other systems such as airbags or suspension. This code sets when messages from this module stop reaching the network. How and where the module is mounted varies a lot between makers.
Symptoms4
- Stability or traction control light on.
- ABS light or a brake system message on some vehicles.
- Hill start assist or other features that rely on tilt and acceleration data disabled.
- Other lost-communication codes for stability sensors set at the same time.
Possible causes6
- Damaged or loose sensor module connector.
- Moisture or water near the module on the floor or in the console.
- Blown module power fuse.
- Weak battery or low voltage.
- Open or shorted CAN wiring to the module.
- Internal failure of the module or of the unit it is combined with.
How to diagnose5
- Use the service information to find the module and see whether it is separate or built into the ABS or airbag module.
- Read codes from all modules and note whether the module shares power or a connector with others that also lost contact.
- Inspect the connector and mounting area for moisture or corrosion.
- Measure power and ground at the module connector with the key on.
- Check the CAN lines to the module and compare their resistance with the manufacturer specification.
How to fix5
- Replace the blown fuse and charge or replace the battery.
- Clean the connector and fix the source of moisture.
- Repair damaged power or network wiring.
- Replace the module if proven faulty, then program or calibrate it with a scan tool as the manufacturer requires.
- Clear codes in all modules and confirm the code does not return after driving.
Repair cost
In Saudi riyals; the highlighted part is the expected range for this fault.
The cost is small for a connector or fuse repair, and rises when the module must be replaced and calibrated, especially if it is built into the airbag or ABS module.
Prices are rough estimates for common cars at independent workshops and vary with the car and the source of the part.

Frequently asked questions
How is this sensor different from a yaw rate sensor?
A yaw rate sensor only measures rotation, while a multi-axis sensor combines rotation and acceleration in several directions in one unit, so losing it affects more systems.
Should I be careful if the module is part of the airbag system?
Yes. If the module belongs to the airbag system, do not unplug or handle its connector yourself. Leave testing to a specialist to avoid accidental deployment or disabling the airbags.
This guide is for information only and does not replace an inspection by a qualified technician. If the fault involves brakes, steering, engine temperature, electrics or refrigerant, do not attempt the repair yourself.
