Description

The Wabco 4460046030 is an ABS-E Basis 4S/4M 12V ABS ECU, a crucial component in vehicle braking systems. This controller is designed for use in a variety of automotive applications where anti-lock braking is required. The unit features OE specification adherence, ensuring reliable performance and compatibility. Its robust design provides a protection class of IP 30. The ABS ECU operates within a temperature range of -40°C to +75°C, guaranteeing functionality in diverse climates. Measuring 40 x 126 x 135 mm, it’s designed for efficient integration into the vehicle’s brake system with a mounting configuration of 3x Ø 7.5 mm holes spaced 112x122 mm apart.

Key Features & Benefits

This little unit is basically the brains behind your anti – lock braking system. It monitors wheel speed sensors – there's one at each wheel – and figures out if any of them are starting to lock up during braking. It then rapidly pulses the brakes on those individual wheels to keep them rotating, allowing you to maintain steering control. It also works with other systems like traction control, and sometimes even stability control, depending on the vehicle. It handles all the calculations and sends signals to the hydraulic modulator to make it all happen. Think of it as the conductor of an orchestra. All the wheel speed sensors are the musicians, and the ABS ECU tells each brake “musician” when and how much to ease up, preventing a skid. It’s a key component in the overall braking system, working with the master cylinder, lines, and calipers, but it's managing how the braking force is applied to each wheel.

Symptoms, Risks & Replacements

It’s hugely important for safety, plain and simple. 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, and when they lock, you lose steering control. You’ll notice if it’s failing because the ABS warning light on your dash will illuminate. Sometimes you might feel a pulsing in the brake pedal during normal braking, or it might just completely stop working. It’s a relatively small part, but it makes a massive difference in how well you can stop, particularly in emergencies. You can often find a replacement pretty easily – Fixparts Online carries a good range of these, for example – but it’s best to get it sorted quickly if you suspect it’s gone bad.
