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 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.





INSPECTION PROCEDURE

NOTICE:
When replacing the yaw rate and acceleration sensor, perform zero point calibration Calibration.

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 U Code Charts.

PROCEDURE

1. REPLACE YAW RATE AND ACCELERATION SENSOR

(a) Replace the yaw rate and acceleration sensor Removal.

NOTICE:
Check the yaw rate and acceleration sensor signal after replacement Test Mode Procedure.

HINT
If troubleshooting has been carried out according to Problem Symptoms Table, refer back to the table and proceed to the next step Problem Symptoms Table.
