Ford replied with "Sure-Track", adding it only the rear wheels of its Lincoln Continentals. Chrysler worked with the Bendix Corporation to come up with a computerized, four-wheel ABS system called "Sure Brake" for its 1971 Imperial. The result premiered in 1970, when Hans Scherenberg presented the analog-electronic "Mercedes-Benz/Teldix Anti-Bloc System" to the media at the test track in Untertürkheim.Įngineers got equally busy overseas. In 1966, the company began collaborating with the Heidelberg electronics specialist Teldix, which was later taken over by Bosch. In 1963, Daimler-Benz started working on its first electro-hydraulic brake control system. The components needed to register the rotational deceleration and acceleration of the wheels without error, including when cornering, on irregular surfaces and in very dirty conditions. The challenge was that, compared to aviation and railways, the automobile required more sensors and faster signal processing.
The work at Daimler began as early as 1953, when Hans Scherenberg, then head of design at Mercedes-Benz, applied for a patent on a system to prevent a vehicle’s wheels from locking under hard braking. But while cost wasn't an issue on a jet capable of Mach 2.04, the task of making ABS cheap and reliable enough for mainstream automotive production fell to the Germans. When a cutting-edge electronically-controlled anti-lock system was developed for the Concorde, it seemed that the British had reached the pinnacle of the technology. The Maxaret anti-lock brake system was also put on motorbike prototypes, and by the '60s, Ferguson Research used it on the world's first four-wheel drive Formula One car, the Climax-powered P99. In the '50s, disc brake pioneer Dunlop came up with a system that could improve the RAF's braking performance by up to 30 percent.
But amazingly, the idea for ABS was not a new one when Bosch and Daimler finally put it the W116 S-Class in the late '70s.īefore World War II, French and German engineers (including Robert Bosch) experimented with numerous anti-slipping systems for the railway and aviation industries. Not only was it the first innovation capable of helping you avoid a crash, it also opened the door for the modern performance car technology we enjoy today. Likewise, when you hit the blue control button, the unit powers up the stoplight circuit.The 1978 introduction of four-wheel multi-channel anti-lock brake systems changed the way we drive forever. Then, when you press the remote’s red supply button, the unit powers up the trailer’s auxiliary circuit in addition to applying air pressure to the red gladhand.

The Express Garage and Express Mobile are equipped with full Scanner light testing equipment, but when the “ABS” switch is placed into the ”By Remote” position, control of the trailer’s auxiliary and stoplight circuits (the two circuits required to run the ABS self- test) is taken away from the Scanner and given over to your unit’s remote control. Express Garage and Express Mobile – Using the ABS Switch Even though testing and diagnosing ABS systems is a remarkably “user friendly” operation, the complexities of today’s vehicles make it essential that you know the correct testing protocol for the type of ABS you are servicing.

There are many sources for code readers, here are two:ĪBS technology is evolving rapidly new systems and procedures are arriving almost daily. Furthermore, many code readers are designed to read any code- tractor or trailer ABS, engine management systems, even transmission codes. In any case, the most cost-effective way to read fault codes is with the specialty equipment designed for that purpose. Chances are, your shop has already gotten into electronics, and you may already have equipment capable of reading codes. Like it or not, we live in a time when you can’t even adjust the idle speed on many trucks without a laptop computer.
Each system has its own procedure, so you must know the correct procedure for the system you’re servicing.įault code reading and clearing from the 7-pole socket is beyond the scope of our equipment. Many ABS systems have self-diagnosing abilities too, blinking out fault codes on the ABS status light, or illuminating LEDs on the controller. Testing these systems is simply a matter of using your Square Wheel Industries Trailer Lighting Tester to power these two circuits and allowing the ABS to test itself.
Other systems self-test each time the stoplight circuit is powered (minus the chuffing). If the ABS status light fails to light up, blinks, or comes on and stays on, an ABS fault is indicated. The ABS status light comes on for 3 to 5 seconds, and you might hear the air valves “chuffing”. During startup, when the auxiliary circuit is first powered, the ABS runs a self-check. Trailer ABS systems contain an on-board computer with self-testing and diagnostic capabilities.
