What does traction control do on a Toyota Tundra?
ATRAC – Or A-TRAC, this is Toyota’s Active Traction Control. It applies the brakes to stop a spinning wheel. Can also retard engine timing to reduce power applied to the driveline (to prevent breakage of driveline parts).
What does TRAC do on a Toyota Corolla?
When one of the wheels begins to slip, TRAC applies a wheel brake individually to the tire without traction and reduces engine output to help assist the driver with control of the vehicle in a straight line. ATRAC – Or A-TRAC, this is Toyota’s Active Traction Control.
How does traction control work in a truck?
The truck does not intervene when traction or directional stability is lost. Normal (no buttons pressed, no dash lights on) = Truck will detect wheel spin and retard engine timing along with application of the brakes to the spinning wheel as needed. Vehicle Stability Control is on.
When does ATRAC go on on a Toyota truck?
ATRAC is defaulted to “ON” when the truck is started in any drive mode (2WD, 4HI, 4LO).

What happens when a Toyota truck loses traction?
Great for turns, when the outside wheel has to spin faster than the inside wheel. But not so great if a wheel loses driving traction, because the differential will send all of its torque to the spinning wheel and not push the truck forward. Here’s how Toyota have enabled us to keep traction in slippery situations.
What do I need to know about traction control?
4LO – One Push (“Traction Control OFF” light on). Puts the truck into the same mode as the 4Hi setting above and allows the tires to spin at speed, clearing mud and snow from the tread. Tire pressures – dropping to about 15 psi of tire pressure in the snow and sand will create a larger footprint for the tire to grab with.
How does Trac-traction control work in a car?
TRAC – Traction Control helps maintain traction on wet, icy, loose or uneven surfaces. When one of the wheels begins to slip, TRAC applies a wheel brake individually to the tire without traction and reduces engine output to help assist the driver with control of the vehicle in a straight line.
What causes the traction control to go offline?
The traction control computer in your vehicle is the “brain” that controls the entire system. A defect, corroded contacts or water damage in this computer can result in the entire system going offline, which will turn on the TCS warning light. As the TCS and ABS often share a computer, this may affect your ABS system and turn on that light, too.
What to do when your traction control warning light comes on?
If a fluke in the TCS system triggered the warning light, it should turn stay off when you restart the engine. If it comes back on, it’s likely time to call a mechanic and get a system diagnosis. Until it’s fixed, drive gently and avoid hard acceleration that could result in the wheels slipping.
