DTC C1210: Zero Point Calibration of Yaw Rate Sensor Undone; DTC C1336: Zero Point Calibration of Deceleration Sensor undone [02/2019 - 12/2021]: Description
The skid control ECU (brake booster with master cylinder assembly) receives signals from the yaw rate and acceleration sensor (airbag ECU assembly) via CAN communication.
The airbag ECU assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition using 2 circuits (GL1, GL2).
HINT:
If there are malfunctions in the bus lines between the yaw rate and acceleration sensor (airbag ECU assembly) and the CAN communication system, DTCs U0123 (Lost Communication with Yaw Rate Sensor Module) and U0124 (Lost Communication with Lateral Acceleration Sensor Module) will be stored.
These DTCs (C1210 and C1336) will also be stored when zero point calibration has not been completed.
