Thanks for the heads up.
I knew about the 98-02 trooper part sharing, but I did not know the origin of manufacture.
Assuming its the ABS module, I went ahead and tracked down an abs module from a '99 VX.
It's sitting at my feet right now, for $150. Sure beats the $2,700 ($2,400 from Merlin) that I would pay for new.
I have an appointment on Saturday for my mechanic to grab the code and see if in fact it is my module.
