ABS

Antilock Braking Systems
The antilock braking system in the Vehicross tends to fail. Most failures cause the ABS light to come on and ABS to be deactivated. These are most often caused by a fault within the controller unit, specifically the modulator valve. However, this valve is contained in a potted unit that must be replaced as a unit. It can cost over $3000 to get it replaced by a dealer. Fortunately, there are some other options.

Rebuilding
The Bosch ABS unit is pretty well sealed, and is very difficult to rebuild. However, one site does claim to be able to rebuild them for a little over $100. (Anyone actually done this?)

Salvaging
The module is part number 8971621921. In general, you can transplant from a similar Isuzu Trooper body, so long as it has 4-wheel disc brakes. In particular, look for these vehicles:
 * 1998-2002 Isuzu Trooper 4X4
 * 1998-1999 Honda/Acura SLX 4X4

Debugging
The Vehicross.info site has information on how to recover the ABS trouble codes without using a reader tool.
