C1419

BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: C1419,C1435: 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 and acceleration sensor 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 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.





WIRING DIAGRAM

Refer to DTCs C1232, C1243, C1245 and C1381 C1232.

INSPECTION PROCEDURE

NOTICE:
When replacing the yaw rate and acceleration sensor, perform calibration Programming and Relearning.
