What does Service RSC mean?

RSC stands for "roll stability control" a problem has been detected with the antilock 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 Control

Anti-Lock Brake System (ABS) with Traction Control and Roll Stability Control (RSC) 
The ABS consists of the following components:

·         ABS module

·         Hydraulic control unit (HCU)

·         Front wheel speed sensors

·         Front wheel speed sensors rings

·         Rear wheel speed sensors

·         Rear wheel speed sensor rings

·         Stability control sensor cluster

·         Stability traction control switch

·         Steering wheel rotation sensor

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.

The front 
wheel speed sensor rings are integral to the front hub and bearing assemblies.
