VEHICLE STABILITY CONTROL SYSTEM, Diagnostic DTC:C1419, C1435

DTC Code DTC Name
C1419 Acceleration Sensor Internal Circuit
C1435 Yaw Rate Sensor Internal Circuit

DESCRIPTION

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

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 there is trouble in the bus lines between the acceleration sensor (airbag sensor assembly) and the CAN communication system, DTCs U0124 (Lost Communication with Lateral Acceleration Sensor Module) are set.

These DTCs are also output when calibration has not been completed.

DTC No. DTC Detection Condition Trouble Area
C1419 A data malfunction signal is received from the acceleration sensor. Acceleration sensor (Airbag sensor assembly)
C1435 A data malfunction signal is received from the yaw rate sensor. Yaw rate sensor (Airbag sensor assembly)
