ABS Basics - A Review What do the S and M stand for when used to describe an ABS System such as 2S/M? The S is a convention used to denote the sensors in an ABS system, while the M refers to the modulator valves. Describing an ABS system as 2S/M simply means that it uses 2 sensors and modulator valve. The basic 2S/M system is used to monitor two sensors attached to each wheel end of one axle, which is controlled by one modulator valve that receives instructions from an electronic brain called an ECU. Why would one use a 4S/2M system on a trailer instead of the basic 2S/M system? The configuration of an ABS system typically depends upon the intended use of the trailer unit. While a 2S/M system may meet the minimum legal requirements, geographic road conditions can make a 4S/2M system more logical by offering added control of two axles independently or side-by-side control of the trailer. Full type trailers require 4S/2M systems. What makes tractor and trailer ABS systems different? Many modern tractor ABS systems use 4S/4M systems, and others can be 6S, depending upon the number of sensors used and the number of axles present on the tractor unit. Trailers, on the other hand, typically employ a 2S/M system with sensors present on only one axle. How does a trailer ABS system function with two tanks? Historically, two tanks have been used on trailers to protect pressures and ensure that the braking system would have charged air. However, due to the modern 8x air volume requirement, a single jumbo tank could be used. The use of two tanks is still typically used in applications where there are tight spaces, or a number of auxiliary devices are used. On which tank should I install my ABS valve? As a general rule, valves should be installed centrally on a trailer. In other words, the tank that is closer to the center of the trailer in terms of length of plumbing lines, should receive the valve. The reason for this is simply to ensure proper brake timing and balance. On which axles should I install my ABS sensors? ABS sensor location ultimately depends upon whether the trailer is equipped with spring or air suspension. Typically, with spring suspension, sensors should be installed in the axle furthest forward on the trailer, while with air suspension, sensors should be installed to the rear axle in doubleaxle units and the middle axle of triple axle units. The general principal is to attach the sensors to the axle, or wheel ends, that are most likely to lockup during a hard braking event. Need more information?
