Invalid Data Received from Deceleration Sensor |
|
DTC |
C1443 |
Invalid Data Received from Yaw Rate Sensor |
DESCRIPTION
The skid control ECU (brake actuator assembly) receives signals from the yaw rate and acceleration sensor (airbag sensor assembly) via the CAN communication system.
The airbag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition.
