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 (malfunction in CAN communication with the yaw rate sensor) and U0124 (malfunction in CAN communication with the acceleration sensor) are set.
These DTCs are also output when calibration has not been completed.

WIRING DIAGRAM

Refer to DTCs C1232, C1243, C1245 (YARIS_NCP93 RM000001RFV0AMX.html).

INSPECTION PROCEDURE

NOTICE:
When replacing the yaw rate and acceleration sensor, perform the zero point 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 (YARIS_NCP93 RM000000YUO0DIX.html).
1.REPLACE YAW RATE AND ACCELERATION SENSOR

  1. Replace the yaw rate and acceleration sensor (YARIS_NCP93 RM000001BYV012X.html).

    NOTICE:
    Check the yaw rate and acceleration sensor signal after replacement (YARIS_NCP93 RM000000XHT08IX.html).
    HINT:
    If troubleshooting has been carried out according to the Problem Symptoms Table, refer back to the table and proceed to the next step (YARIS_NCP93 RM000000XHN0AXX.html).
