Circuit Description
WARNING: This page is about a different car, the 2006 Toyota Tundra and 2005 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.
The master cylinder solenoid (skid control ECU) receives signals from the yaw rate & deceleration sensor via the CAN communication system.
The yaw rate sensor has a built-in deceleration sensor.
If there is trouble in the bus lines between the yaw rate & deceleration sensor and the CAN communication system, the DTC U0123/62 (yaw rate sensor communication trouble) and U0124/95 (deceleration sensor communication trouble) are output.
These DTCs are also output when the calibration has not been completed.
