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