Discovery II ABS Fault Codes
Complete reference library of ABS fault codes for the 1999–2004 Land Rover Discovery II. These codes correspond to the blink codes output by the ABS ECU diagnostic procedure. Each entry explains the fault and what to inspect.
Diagnose and clear ABS faults with the proper diagnostic tool for your vehicle.
RSW Solutions offers diagnostic tools that communicate directly with Land Rover’s proprietary ABS systems. Read the fault codes electronically rather than counting blink sequences.
