Wabco 4492121200 ABS Connector Cable

Description

The Wabco 44921200 is an ABS Connector Cable designed for use in Air Brake Systems, specifically within EBS (Electronic Braking System) applications. This cable is typically found connecting the trailer's ABS system to the tractor unit. With dimensions of 96 x 342 x 343 mm, this drawbar type cable provides a reliable power supply line, compatible with ISO 24 V systems, and adheres to OE specifications. Its robust construction and precise engineering ensure dependable signal transmission and contribute to the overall safety and performance of the braking system.

Key Features & Benefits

This cable basically connects the wheel speed sensors on your trailer to the ABS control module. It’s a wiring harness, a bunch of wires bundled together with a connector on each end. Those sensors read how fast each wheel is turning and send that info back to the ABS module. It's a fairly simple part, but it does a critical job. Think of your trailer’s ABS system like a safety net. It prevents wheel lockup during braking, especially important when you’re hauling a load. This cable is how the system gets the information it needs to work properly. Without accurate speed readings from each wheel, the ABS can’t effectively modulate the brakes. It’s part of the communication network for the entire trailer braking system.

Symptoms, Risks & Replacements

If this cable gets damaged – corrosion, a broken wire, a loose connection – the ABS system won't get the right signals. You’ll likely notice if it’s completely broken, you might get an ABS warning light on your dash. But sometimes it’s subtle; maybe the ABS activates when it shouldn't, or doesn’t activate when it should. Either way, it compromises your braking safety. It acts like a shield, protecting against skids. We carry these at Fixparts Online, and it’s one of those parts where replacing it proactively is a good idea if you suspect any issues, especially if you do a lot of hauling or operate in harsh conditions.
