This 4S/4M module is a critical component of the anti-lock braking system, preventing wheel lockup during braking events. It's suitable for a wide range of applications, ensuring reliable performance in demanding conditions. The module measures 136 x 40 x 181 mm and features a mounting configuration with 4x Ø 7.5 mm holes at a 163x122.5 mm spacing. With an IP 40 protection rating and a broad operating temperature range of -40°C to +85°C, this module is engineered for durability and consistent operation. It meets OE specification for optimal compatibility and performance.

Key Features & Benefits

This module is basically the brain behind your anti – lock braking system. It constantly monitors the speed of each wheel using those sensors – that’s what the 4S part means, four sensors. Then, it uses that information to control the brake pressure to each wheel individually, that’s where the 4M – four modulators – comes in. It prevents your wheels from locking up during hard braking, and also manages traction control if your vehicle has that integrated. It's a pretty complex piece, doing a lot of calculations very quickly. Think of it as a safety system manager. It’s not directly making your brakes work – your brake pedal and master cylinder do that. It's stepping in when you need it most, during emergency stops or slippery conditions. It’s constantly watching what’s happening with each wheel and making adjustments to maximize stopping power while keeping you steering. It’s an electronic component, so it needs power to operate, hence the 24 – volt specification.

Symptoms, Risks & Replacements

Well, without this, you lose the benefits of ABS. Your wheels can lock up, meaning you lose steering control during braking, and your stopping distances get longer. It’s a really significant safety feature. You’ll notice if this fails, usually by the ABS warning light illuminating on your dash. It might also affect your traction control, if equipped. A faulty module can even cause your brakes to feel ‘spongy’ or uneven. We carry these at Fixparts Online, among other places, if you’re looking to get one. It's one of those parts you really want to keep functioning properly.
