C1279 2017 Toyota RAV4 Code - Acceleration Sensor Output Voltage 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 C1279 2017 Toyota RAV4 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 C1279 2017 Toyota RAV4?
- 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
