The ABS/ESP ECM checks a vehicle driving status, a road status, and a steering status. And then it operates VSM system. The integrated control of ABS/ESP and EPS CM (MDPS=Motor Driving Power Steering) makes a vehicle's driving safety improve more and more.
The EPS CM (MDPS=Motor Driving Power Steering) sets this DTC if it hasn't gotten any data related to VSM from ABS/ESP ECM.
