C1648 CAN signal error ECM for SCC (Check ECM) - 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 monitors CAN messages for a normal SCC system's operation and if the invalid messages from ECM are detected, this DTC is set.
