BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS  VEHICLE STABILITY CONTROL SYSTEM  C1419  Acceleration Sensor Internal Circuit  C1435  Yaw Rate Sensor Internal Circuit  


DESCRIPTION

These DTCs are stored when the skid control ECU (brake actuator assembly) receives an internal malfunction signal from the yaw rate and acceleration sensor (airbag ECU assembly).

The airbag ECU assembly has a built-in yaw rate and acceleration sensor and detects the vehicle's condition.

DTC No. Detection Item DTC Detection Condition Trouble Area
C1419 Acceleration Sensor Internal Circuit A data malfunction signal is received from an acceleration sensor. Acceleration sensor (airbag ECU assembly)
C1435 Yaw Rate Sensor Internal Circuit A data malfunction signal is received from a yaw rate sensor. Yaw rate sensor (airbag ECU assembly)

CAUTION / NOTICE / HINT

NOTICE:
·

When replacing the yaw rate and acceleration sensor (airbag ECU assembly), perform zero point calibration.
