The ESC generally accepts a nominal 50 Hz PWM servo input signal whose pulse width varies from 1 ms to 2 ms. When supplied with a 1 ms width pulse at 50 Hz, the ESC responds by turning off the motor attached to its output. A 1.5 ms pulse-width input signal drives the motor at approximately half-speed.
To prevent this, the key fob does not use the same unlock code each time but a rolling code system; it contains a pseudorandom number generator which transmits a different code each use. [9] The car's receiver has another pseudorandom number generator synchronized to the fob to recognise the code. To prevent a thief from simulating the ...
The bitting code is used in conjunction with a key's Depth and Spacing Number to completely determine all relevant information regarding the key's geometry. [1] Each number in the bitting code corresponds to a cut on the key blade. For example, a bitting code of 11111 with Depth and Spacing Number 46 specifies a Kwikset key with five shallow cuts.
ESC is described as the most important advance in auto safety by many experts, [37] including Nicole Nason, administrator of the NHTSA, [38] [39] Jim Guest and David Champion of Consumers Union of the Fédération Internationale de l'Automobile (FIA), [40] [41] E-Safety Aware, [42] Csaba Csere, former editor of Car and Driver, [43] and Jim Gill ...
An ECU from a Geo Storm. An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.

The predecessor of modern electronic traction control systems can be found in high-torque, high-power rear-wheel-drive cars as a limited slip differential.A limited-slip differential is a purely mechanical system that transfers a relatively small amount of power to the non-slipping wheel, while still allowing some wheel spin to occur.
The smart key allows the driver to keep the key fob pocketed when unlocking, locking and starting the vehicle. The key is identified via one of several antennas in the car's bodywork and an ISM band radio pulse generator in the key housing. Depending on the system, the vehicle is automatically unlocked when a button or sensor on the door handle ...
