Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
DTC B1001-55: SCC Present Error - Coding Code Error: General Description
The Cluster memorizes what control modules are installed on the vehicle through CAN-BUS communication. The vehicle optional information is added in cluster during End Of Line (EOL) coding procedure. A DTC will be set if the optional information is different when compared between memorized optional information from CAN-BUS and optional information from EOL coding procedure.
During assembly, EOL communication will verify that a DTC is not set during DTC searching. When repairing or replacing cluster, it is necessary to set the variant code using KDS in order to synchronize the optional components on the vehicle.
