C1688 MDPS signal error - General Information

Component Location





General Description

CAN communication is a circuit that consists of a low line and a high line and two resister, one in the Cluster and one in the PCM. The CAN is used for communication with each control module(PCM, 4WD ECM, TCM, ABS).
Vehicle Stability Management (VSM) is a function to maintain optimum steering stability and braking distance while a vehicle slips. When the vehicle slips, the ESC sends required torque value to EPS ECU via the CAN line. After receiving the torque value, the EPS ECU performs steering control.

DTC Description

The HECU checks the CAN communcation lines and sets this code if an abnormal EPS message is received.
