C1279 2018 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.
