TRACS System
TRACS is an optional traction control system that operates in conjunction with ABS system. If vehicle speed is less than 25 MPH and one of the drive wheels starts to slip, control module starts pump in hydraulic modulator, which pumps brake fluid to brake caliper of wheel that is slipping, applying braking force so both drive wheels have same speed. If vehicle is braked, brake light contact closes at same time as pressure switch breaks a circuit to control module. TRACS control stops and system goes into ABS control standby mode.
Because TRACS system is intended as an assist to starting on slippery surfaces, it is most effective at speeds less than 15 MPH, and less so between 15-25 MPH. TRACS is completely disengaged at speeds grater than 25 MPH. Hydraulic pump is in continuous operation while TRACS is engaged.
