Code C0371 Toyota Description

The skid control Electronic Control Unit (ECU) receives signals from the Yaw Rate and Deceleration sensor via the CAN communication system. The yaw rate sensor has a built-in deceleration sensor and detects the vehicle's condition using 2 circuits (GL1: G sensor 1, GL2: G sensor 2). The Engine Control Module (ECM) monitors the Yaw Rate and Deceleration sensor. The ECM sets the OBDII code when the Yaw Rate and Deceleration sensor is not to factory specifications.
