CAN communication Line consists of Low and High line so that each ECU can communicate their information for each other.
In order to adopt FATC control for SPAS, SPAS and FATC communicate each other.
The SPAS ECU sends the request messages, such as a temperature signal for compensation, to the FATC through CAN bus line for SPAS.
The SPAS ECU check the CAN communication line for normal control and if the FATC message is not received for a 0.5 second, this DTC is set.
