Toyota 4Runner: Acceleration Sensor Internal Circuit (C1419,C1435)
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.
