ABS ECU/Valve Assembly Replacement 4005001030 For Volvo & Mack Trucks - Aftermarket For OE S4005001037

This is an aftermarket ABS ECU (Electronic Control Unit) and valve assembly module for certain Volvo and Mack trucks. It's designed as a direct replacement for the OEM part number S4005001037 (also cross-references to numbers like 4005001030, 8235-S4005001030, etc.).

If your truck's ABS warning light is on or the system isn't functioning properly, a faulty ECU/modulator valve assembly could be the cause. This unit is built with high-quality materials and should match the original's specs for fit and function.

Installation is generally a bolt-on and plug-in procedure, but due to the critical safety nature of the ABS system, professional installation by a qualified technician is highly recommended. Always double-check your truck's exact make, model, and the part number on your old unit to ensure this is the correct replacement. A cost-effective solution compared to a dealer part.
