C1243 Code - Acceleration Sensor Stuck Malfunction
Quick Answer
The Skid Control ECU (Brake Actuator Assembly) receives signals from the Yaw Rate Sensor and Acceleration Sensor (Airbag Sensor Assembly) via the Controller Area Network (CAN) communication system. Common causes include Acceleration Sensor Calibration, Faulty Yaw Rate Sensor and Acceleration Sensor (Airbag Sensor Assembly), Airbag Sensor Assembly harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C1243 Description
The Airbag Sensor Assembly has a built-in Yaw Rate Sensor and Acceleration Sensor and detects the vehicle's condition.
If there is trouble in the bus lines between the Yaw Rate Sensor and Acceleration Sensor (Airbag Sensor Assembly) and the CAN communication system, the Diagnostic Trouble Code (DTC) U0124 (malfunction in CAN communication with the acceleration sensor) is output.
These DTCs are also output when calibration has not been completed.
What are the Possible Causes of the DTC C1243?
- Acceleration Sensor Calibration
- Faulty Yaw Rate Sensor and Acceleration Sensor (Airbag Sensor Assembly)
- Airbag Sensor Assembly harness is open or shorted
- Airbag Sensor Assembly circuit poor electrical connection
How to Fix the DTC C1243?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the C1243 code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
