There are multiple companies that repair ABS modules. Many times you can send them your module, they will repair it and return. See this
LINK.
They don't list your specific vehicle but they imply they can repair most based on the manufacturer of the ABS unit. You might contact them and see if they can help.
I used such a company once to get an ABS control unit for an AUDI repaired. It worked really well after the repair.
