The Wabco Ecas Control Box, MPN 4461560200, is a vital component within a semitrailer's electronic suspension system, specifically for trailers equipped with lifting axles and central electronics. This device manages and controls the air suspension, contributing to vehicle stability and ride comfort. The control box is designed to OE specification and operates within a temperature range of -40°C to +70°C at a voltage of 18 to 32 V. Its robust construction, featuring protection classes IP 6K6K and IP 6K9K, ensures reliable performance even in harsh operating conditions. The dimensions of the unit are 107 x 147 x 175 mm. This thing basically manages your Electronic Controlled Air Suspension system. It receives signals from sensors all around the vehicle – ride height, wheel speed, steering angle, things like that – and uses that information to control the air springs and shock absorbers. It adjusts the air pressure in each spring to keep the vehicle level, provide a comfortable ride, and handle changes in load. It handles things like automatic leveling when you load up the car, and can even adjust the suspension stiffness based on how you're driving. Think of it as the brain of your air suspension. It’s taking input from everywhere and telling the system what to do. It directly controls the air compressor, the solenoid valves that let air into and out of the springs, and monitors everything to make sure it's working correctly. Without it, the air suspension will just… well, it won’t work right. It’ll likely either deflate completely, stay fully inflated, or just be stuck in one position. It's usually found tucked away somewhere under the passenger side, or in the engine bay. If this box goes bad, you’ll notice if your vehicle is sitting unevenly, or maybe the ride is really harsh or super bouncy. You might get a warning light on the dash about the suspension. A failing unit can also cause the compressor to run constantly, trying to keep the air springs inflated, which can burn it out – and a compressor replacement is a lot pricier. It’s important for both ride comfort and handling, but also to prevent damage to other components. If you’re seeing issues with your air suspension, this is a pretty common culprit. You can find replacements for these at places like Fixparts Online, but diagnosing it correctly is the first step. Your satisfaction is our priority: ECAS Control Box (MPN 4461560200) is covered for 12 months!
