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.
