VEHICLE STABILITY CONTROL SYSTEM(for Hydraulic Brake Booster), 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 (airbag sensor assembly) via the CAN communication system.

The airbag sensor assembly has a built-in acceleration sensor and detects the vehicle condition using 2 circuits (GL1, GL2).

If there is trouble in the bus lines between the yaw rate and acceleration sensor (airbag sensor assembly) and the CAN communication system, DTCs U0123 (malfunction in CAN communication with the yaw rate and acceleration sensor) and U0124 (malfunction in CAN communication with the acceleration sensor) are stored.

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

DTC Code 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 and acceleration sensor. Yaw rate sensor (Airbag sensor assembly)

CAUTION / NOTICE / HINT
