Wabco 4496321000 ECAS Cable

Description

The Wabco 4496321000 ECAS Cable is a vital component within trailer air brake systems, specifically designed for ECAS (Electronically Controlled Air Suspension) applications. It serves as the connection point between the ECAS remote control unit and the broader air brake network. This cable features an open 4-strand connection with push-on contacts and a PG11 screw connection on one end, and a socket connection for the remote control unit on the other. Its robust design and OE specification ensure reliable communication and precise control of the air suspension system, contributing to enhanced vehicle stability and safety. The cable's dimensions are 40 x 40 x 330 mm.

Key Features & Benefits

This cable basically handles the electronic communication between your tractor and trailer’s air brake systems. It carries signals for things like brake application, trailer ABS activation, and even diagnostic information. Think of it as the nervous system connecting those two parts – it sends the messages back and forth to make sure everything works in sync. It’s not actually part of the air brakes themselves, it just lets them talk to each other. It connects the electronic brake control module on your truck to the trailer’s ABS module, if the trailer has one. That communication is critical for things like stability control and ensuring the trailer brakes activate correctly with the truck. Without a good connection here, the trailer system might not respond when you hit the brakes, or it could get false signals. It allows the truck’s computer to ‘see’ what the trailer is doing, and adjust accordingly.

Symptoms, Risks & Replacements

It's vital for safety, plain and simple. A faulty ECAS cable can cause erratic trailer braking, stability issues, or even complete brake failure on the trailer. You’ll notice if it’s starting to go bad - things like the ABS light coming on, or the trailer feeling unstable when you brake. Ignoring it isn’t a good idea. You can find these cables pretty easily, places like Fixparts Online carry them. It’s a relatively simple repair, but a really important one, because it’s the link between your safety systems.
