C1443/34 - Invalid Data Received from Yaw Rate Sensor
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 condition.
INSPECTION PROCEDURE
NOTICE:
When replacing the yaw rate and acceleration sensor, perform zero point calibration Programming and Relearning.
PROCEDURE
1. CHECK DTC
(a) Clear the DTCs Vehicle Stability Control System (for ADVICS Made).
(b) Start and idle the engine for 60 seconds, and then stop the engine.
(c) Check if the same DTC is recorded Vehicle Stability Control System (for ADVICS Made).
Result:
B -- USE SIMULATION METHOD TO CHECK
A -- REPLACE YAW RATE AND ACCELERATION SENSOR
