VEHICLE STABILITY CONTROL SYSTEM, Diagnostic DTC:C1210 and C1336

DTC Code DTC Name
C1210 Zero Point Calibration of Yaw Rate Sensor Undone
C1336 Zero Point Calibration of Acceleration Sensor Undone

DESCRIPTION

The skid control ECU receives signals from the yaw rate and acceleration sensor via the CAN communication system.

The yaw rate sensor has a built-in acceleration sensor and detects the vehicle's condition using 2 circuits (GL1, GL2). If there is trouble in the bus lines between the yaw rate and acceleration sensor and the CAN communication system, DTCs U0123 (yaw rate sensor communication trouble) and U0124 (acceleration sensor communication trouble) are stored.

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

DTC No.
