Storey Wilson of RSWSolutions has released a product called the ABS Amigo that can be used to read and clear Land Rover Discovery Series II ABS fault codes.  I'll be doing a complete article on this product soon.  In the meantime, he has also compiled a list of codes and how to go about diagnosing the problems associated with each.  This is a **FANTASTIC** resource for DII owners.  I HIGHLY recommend the ABS Amigo and the diagnostics write-up on his website.
