# ABS Module 850 V70 S70 C70

The **ABS Module 850 V70 S70 C70** refers to the Anti-lock Braking System control module used in select Volvo models, specifically the **850 (1993–1997), V70, S70, and C70 (1998–2000)**. This module monitors wheel speed sensors and helps prevent wheel lockup during braking by modulating brake pressure. Common issues with this module include intermittent ABS warning lights, non-functioning speedometers, or traction control problems, often due to internal solder joint failures. Replacement or repair of the module restores proper ABS and traction control functionality.
