Title: BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: ELECTRONICALLY CONTROLLED BRAKE SYSTEM: C1442,C1443; Invalid Data Received from Deceleration Sensor; 2018 MY Camry HV [07/2017 - 09/2018]

DTC

C1442

Invalid Data Received from Deceleration Sensor

DTC

C1443

Invalid Data Received from Yaw Rate Sensor

DESCRIPTION

The airbag sensor 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 sensor assembly) via the CAN communication system.

DTC No.
