This might not be well received by the Powers-That-Be, but on eBay, an extensive pdf downloaded repair manual, (including diagnostics and trouble shooting), is available for less than $5.00 for many Grand Cherokees.
See: eBay user ID: rarebooksz1.
I got mine, and solved many issues I had with my '97 ZJ.

Something is going on with your electronic brake control module (EBCM) which is delivering "rough road" data to the ECM. This could be a faulty sensor in the system, but I suggest you have the EBCM checked by a dealer.
