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 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 a malfunction in the bus lines between the yaw rate and acceleration sensor and the CAN communication system, DTCs U0123 (Lost Communication with Yaw Rate Sensor Module) and U0124 (Lost Communication with Lateral Acceleration Sensor Module) are set.

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

DTC Code DTC Detection Condition Trouble Area
C1419 A data malfunction signal is received from the acceleration sensor. Yaw rate and acceleration sensor
C1435 A data malfunction signal is received from the yaw rate sensor. Yaw rate and acceleration sensor
