Traction Control: Description
Traction Control System (TRAC) controls engine torque and braking of driving wheels. TRAC is available as an option. TRAC system consists of ABS/TRAC actuator, wheel speed sensors, Anti-Lock Brake System/Traction Control Electronic Control Unit (ABS/TRAC ECU), ABS solenoid relay, motor relay, TRAC cut switch and TRAC OFF indicator light. See Fig 1.
Integrated with ABS system, TRAC helps avoid slippage of driving wheels during acceleration. System maintains optimal driving control during changing road surface conditions upon acceleration. System eliminates need for acceleration pedal operation and improves vehicle stability when starting, accelerating or turning on slippery roads.
