Traction Control System (TCS) Description

TRACTION CONTROL SYSTEM (TCS) DESCRIPTION
The main purpose of traction control is to reduce wheel slip and maintain traction at the driving wheels when road surfaces are slippery. The traction control system reduces wheel slip by braking the wheel that is losing traction. The system is designed to operate at speeds below 56 km/h (35 mph).

HYDRAULIC SHUTTLE VALVES
Two pressure relief hydraulic shuttle valves are included on vehicles with traction control. These valves are located inside the HCU and cannot be serviced separately from the HCU.

TRACTION CONTROL LAMP
The traction control function lamp is located in the transmission range indicator display of the instrument cluster, displaying TRAC, TRAC OFF or neither depending on system mode. The TRAC OFF lamp is controlled by a Traction Control Off switch that is a momentary contact type switch. The Traction Control Off switch is located on the steering column upper shroud.
