You probably have the wrong module for your specific vehicle or the module has the incorrect software version to match your vehicle. Each module is specific to each vehicle; even brand new modules specifically ordered for your vehicle sometime require set up and calibration information to be updated. When you get your module from the wrecking yard, used sales source or even new; there is a risk that the module will not work. The other computers in your vehicle may recognize the new/used ABS controller as belonging to a differently equipped vehicle and will reject it. Repairing your existing EBCM avoids this costly risk completely.
