DTC C1442/44: Invalid Data Received from Acceleration Sensor; DTC C1443/34: Invalid Data Received from Yaw Rate Sensor [08/2013 - ]: Description

WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.

The skid control ECU (brake booster with master cylinder assembly) receives signals from the yaw rate and acceleration sensor (airbag sensor assembly) via the CAN communication system.
