Anti-Lock Fuses or Relay Replacement
Anti-Lock Braking System (ABS) fuse or relay involves renewing the key electrical protection devices that supply high-amperage power to your vehicle’s ABS hydraulic pump and electronic control unit. With the vehicle turned off and the negative battery terminal disconnected, open the main under-hood power distribution box, locate the dedicated ABS fuse or relay using the cover diagram, and pull the faulty component. Inspect the fuse for a broken filament or test the relay contacts for electrical continuity before inserting a fresh OEM-rated replacement with matching pin configurations and amperage limits.
