DTC C1336: Zero Point Calibration of Deceleration Sensor undone [04/2018 - 08/2021]: Description

The skid control ECU (brake actuator assembly) receives signals from the yaw rate and acceleration sensor (airbag sensor assembly) via CAN communication.

The airbag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle's condition using 2 circuits (GL1, GL2). If a communication error with the yaw rate and acceleration sensor (airbag sensor assembly) is detected, DTCs U0123 (Lost Communication With Yaw Rate Sensor Module) and U0151 (Lost Communication With Restraints Control Module) are stored.

The DTCs are also stored when the calibration has not been completed.
