Source for '89 Bronco ii ABS Control Module

[dfreise]

Anyone know of a source for a replacement control module? Upfix does not do repair work on this model. TIA for any help of suggestions.

No, but, most people would tell you to by pass the RABS. I have never had the module fail, just the valve which just needed a good cleaning on the inlet screen. If you removed the board and took high quality pictures of both sides it might be possible to determine what failed, if you post the pictures. I use to repair old Commodore and Apple computers, leaking or blown capacitors are an issue and I had one power supply give up the smoke just from one bad resistor. I doubt the RABS has any sort of CPU, so, just replacing all the components might work. They did not use SMT back then, so, it is going to be easier to fix then on a newer vehicle.

Thank you. I will be investigating more when the weather warms up.

Here is a link where I post the full RABS diagnosis guide. I would check rockauto for the control box or the dump solenoids.

Wiring diagrams, torque specs, RABS help

Sorry for such a data heavy thread but I'm not sure where to put these exactly. I'm sure they will be useful, though!
