DTC C1442: Invalid Data Received from Deceleration Sensor; DTC C1443: Invalid Data Received from Yaw Rate Sensor [04/2018 - ]: Description

WARNING: This page is about a different variant/trim than selected.

The airbag ECU assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition using 2 circuits (GL1, GL2).

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