Identifying the Brake System
Two ABS systems are available for this vehicle: standard ABS and ABS enhanced with traction control and stability assist. ABS with traction control and stability assist may also be called electronic stability control (ESC), roll stability control (RSC), AdvanceTrac®, or interactive vehicle dynamics (IVD) by the scan tool and other service publications.
Vehicles that are equipped with traction control and stability assist can be identified by the presence of individual left and right rear wheel speed sensors.
Vehicles with standard ABS can be identified by the absence of rear wheel speed sensors.
If the vehicle is equipped with traction control and stability assist, refer to Anti-Lock Control - Traction Control and Stability Assist in this article to continue diagnosis of this system.
