Hello, RSC stands for "roll stability control" a problem has been detected with the anitlock brakes/RSC. The only way to know what has happened is the vehicle must be scanned for trouble code(s). the code will allow the technician to know where the fault lies. it could be a speed sensor, steering sensor or one of many other things. Be advised, until you have repaired and code cleared, the ABS or antilock brakes
will not work.It will not affect the running of the vehicle in any way but no ABS/RSC
Anti-Lock Brake System (ABS) with Traction Control and Roll Stability Control (RSC)
The ABS consists of the following components:
The ABS prevents wheel lock-up by monitoring the wheel speed sensors
and actuating the valves in the HCU which modulates the brake pressure to the brake calipers
. By preventing the wheels from locking up, the driver is able to maintain steering control and stop in the shortest possible distance under most conditions. The traction control system utilizes the same components as the ABS to prevent wheel spin and help maintain vehicle control during acceleration. The roll stability control (RSC) system utilizes the same components as the ABS and the traction control systems and also monitors the steering wheel rotation sensor and the stability control sensor cluster to assist in stabilizing the vehicle during abrupt maneuvers.
How to fix is to take to a qualified repair shop that has tools an knowledge to fix it .
