CAN communication Line consists of Low and High line so that each ECU can communicate their information for each other.
In order to adopt ECM(PCM) control for SPAS, SPAS and ECM(PCM) communicate each other.
When SPAS ECU can not receive CAN message from ECM(PCM) for more than 0.5 sec., SPAS ECU sets this DTC.
