What is ESRS?

ESRS most likely refers to Electronic Stability and Rollover System. It is a vehicle safety system that improves a vehicle's stability by detecting and reducing loss of traction (skidding). When ESRS detects a loss of steering control, it automatically applies the brakes to individual wheels to help 'steer' the vehicle where the driver intends to go. Braking is automatically applied to wheels individually, such as the outer front wheel to counter oversteer or the inner rear wheel to counter understeer. Some ESRS systems also reduce engine power until control is regained.
