C1638 CAN time-out SCC - General Information
Component Location
General Description
The SCC is the shorten word of Smart Cruise Control system. This system has a radar sensor on a vehicle and the SCC ECU calculates the distance between cars going in the same direction by the radar sensor. So this SCC system enables a vehicle to drive with maintaining the constant distance from the car ahead or at a constant vehicle speed. The HECU exchanges signals with SCC ECU through CAN communication.
DTC Description
The HECU checks the CAN communication lines for normal control and if a SCC ECU's message is not received for a certain period, this DTC is set.
