VSM(Vehicle Stability Management) system is a safty system to reduce damage by using ESP, PSB(Pre-safe Seat Belt), SCC, Cluster under condition of a collision predicted. VSM2 control mecanism is as follows.
1. Preceding vehicle approaching : Cluster turns on yellow warning lamp.
2. Preceding vehicle approaching too close : ESP prepares breaking and PSB vibrates seat belt, Cluster turns on red warning lamp to inform danger to driver.
3. Under condition of a collision predicted : PSB retracts seat belt fully, ESP slows down the car and assist for driver to make a proper break force according to situation.
SCC ECU sets this code when the VSM2 function is not available because of brake pedal malfunction, cluster turn indicater control and ESP system having a problem, TCM shift level state error. System recovers to normal condition as soon as the VSM2 function is alright again.
