TRACTION CONTROL, TRAK-LOK, and SECURILOCK
- TRACTION CONTROL is Ford's name for its electronic braking and engine control system that monitors rear wheel slippage and prevents
loss of traction when accelerating. If a Mustang has traction control, it must also have 4-wheel anti-lock
brakes (ABS). Traction control consists of all the components of the ABS system, plus a powertrain
control module (PCM) and a traction control ON/OFF switch. Here's how it works:
When traction control is turned on, the PCM monitors the speed sensors at the wheels and at the transmission and
compares rear wheel speed to the carís road speed. If the rear wheel speed exceeds road speed (loss of traction)
the PCM slows the rear wheels until they regain grip. It does that either by applying ABS braking to
the rear wheels to slow them down, or by sending less fuel to the engine, which has the same effect.
Traction Control is optional on all models except the Cobra. The Cobra has Traction Control
as standard equipment.
- TRAK-LOK is Ford's name for the clutch-type limited-slip differential that is installed as standard equipment in the 8.8" rear
end on the Mustang GT and Cobra. It is a mechanical system. (No ON/OFF switch) The Trak-lok differential includes
all the components of an open differential, plus an S-spring and a set of clutches .
The S-spring pushes the clutches up against the side gears, which causes the clutches to engage whenever one
rear wheel turns faster than the other. In a situation where one rear wheel has little or no traction and
the other one has good traction, the clutches engage and provide torque to both wheels. Two
The base (V6) Mustang comes with a 7.5" open differential (without Trak Lok) as standard equipment. In the
situation described above, this differential will apply all of the car's power to the wheel with little or no
traction. That wheel will spin and the other wheel will not. One wheel burnouts...
- SECURILOCK is Ford's name for the Passive Anti-Theft System (PATS) that has been installed on all Mustangs
since the 1999 model year. It provides a unique electronic signature for each car and truck by matching a specially
coded ignition key with a sensor located in the vehicle. A miniature transponder that contains an antenna and an
integrated circuit is embedded in the ignition key. It uses wireless radio technology to transfer a code between the
key and the car. When the right code is recognized the engine will start. If the code is not recognized, the engine
will not start. In the case of a hot wire attempt or the removal of the ignition lock, the system recognizes that
the correct key has not been used; it shuts the engine down within a second and eliminates the possibility
of it being restarted. A very sophisticated and secure system.
