Wabco 4460046060 ABS Electronic Control Unit 4S/4M 24V

Description

The Wabco ABS-E2 4S/4M 24V is an essential component of a vehicle's anti-lock braking system, designed to prevent wheel lockup during braking events. This electronic control unit is used in heavy-duty vehicles to enhance braking performance and stability, particularly in challenging conditions. The ABS-E BASIC 4S/4M module regulates brake pressure to individual wheels, maintaining steering control and reducing stopping distances. This unit measures 137 x 40 x 126 mm and operates within a temperature range of -40°C to +75°C. It features a protection class of IP 30 (IEC 529) and a mounting configuration utilizing 3x Ø 7.5 mm holes with a hole distance of 112x122 mm. The MPN for this ABS controller is 4460046060.

Key Features & Benefits

This unit is really the brains behind your anti – lock braking system. It monitors wheel speed sensors – there’s one at each wheel – and it uses that information to control the brake pressure to each individual wheel. It’s constantly checking if any wheel is about to lock up during braking. If it senses that's happening, it rapidly pulses the brakes on that wheel, letting it keep rotating just enough to maintain steering control. It also handles a few diagnostic functions, letting you or a mechanic know if there's a problem within the ABS system itself. Think of it as the conductor of an orchestra, but instead of instruments, it’s managing your brakes. It doesn’t actually do the braking—your foot still does that—it just makes sure the braking is done safely and efficiently. It works with the brake master cylinder and the hydraulic lines to achieve that. It receives data, processes it incredibly quickly, and then tells the hydraulic modulator what to do. It’s all about precision control.

Symptoms, Risks & Replacements

It’s a big safety item, honestly. If this thing fails, you lose the anti – lock function. That means in a hard braking situation, especially on a slippery surface, your wheels can lock up. When that happens, you lose steering control. It's like trying to steer a sled that's already sliding—not ideal! While your regular brakes will still work, you don’t have that extra layer of protection and control ABS provides. You’ll notice if it’s failing because the ABS warning light on your dashboard will illuminate, or you might feel pulsing in the brake pedal during normal braking. We carry these at Fixparts Online, and getting it sorted out quickly is always a good idea, given what it does.
