REPLACE YAW RATE AND ACCELERATION SENSOR

DTC C1419 Acceleration Sensor Internal Circuit

DTC 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 trouble 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

INSPECTION PROCEDURE

NOTICE:

When replacing the yaw rate and acceleration sensor, perform zero point calibration (COROLLA_ZRE142 RM000000XHR08KX.html).

HINT:

When U0123, U0124 and/or U0126 is output together with C1419 and/or C1435, inspect and repair the trouble areas indicated by U0123, U0124 and/or U0126 first (COROLLA_ZRE142 RM000000YUO0J7X.html).

1.REPLACE YAW RATE AND ACCELERATION SENSOR

Replace the yaw rate and acceleration sensor (COROLLA_ZRE142 RM000003D8S00IX.html).
NOTICE:
Check the yaw rate and acceleration sensor signal after replacement (COROLLA_ZRE142 RM000000XHT0ATX.html).
HINT:
If troubleshooting has been carried out according to Problem Symptoms Table, refer back to the table and proceed to the next step (COROLLA_ZRE142 RM000000XHN0DUX.html).
