C1419, C1435

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

DESCRIPTION

for Optitron Meter Type:

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, the DTC U0124 (Lost Communication with Lateral Acceleration Sensor Module) is output.

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

for TFT Meter Type:

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

If there is trouble in the bus lines between the yaw rate and acceleration sensor and the CAN communication system, the DTC U0124 (Lost Communication with Lateral Acceleration Sensor Module) is output.

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

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	Note
C1419	Acceleration Sensor Internal Circuit	A data malfunction signal is received from the acceleration sensor.	Acceleration sensor (airbag sensor assembly) (for optitron meter type) Acceleration sensor (yaw rate and acceleration sensor) (for TFT meter type)	-
C1435	Yaw Rate Sensor Internal Circuit	A data malfunction signal is received from the yaw rate sensor.	Yaw rate sensor (airbag sensor assembly) (for optitron meter type) Yaw rate sensor (yaw rate and acceleration sensor) (for TFT meter type)	-

CAUTION / NOTICE / HINT

Note

When replacing the yaw rate and acceleration sensor (airbag sensor assembly), perform zero point calibration and store system information (for optitron meter type).

When replacing the yaw rate and acceleration sensor, perform zero point calibration and store system information (for TFT meter type).
