ABS Description and Operation

Document Preview

Vehicles with RPO JL4 are equipped with an EBC 445V ABS/DRP/TCS/VSES module.

This module provides the following vehicle performance enhancement systems.

  • Antilock Brake System (ABS)

  • Dynamic Rear Proportioning (DRP)

  • Traction Control System (TCS)

  • Vehicle Stability Enhancement System (VSES)

  • ...
