The p1698 code is for the (bus) that is how the computers commmunicate with each other and also how the scan tool talks to the computers.
There is a common problem with these vans, that would be a good place to start. The battery will leak acid onto the wires underneath the battery. If you remove the battery and battery tray you will be able to see the large wiring harness under the battery. Inspect all of the wires underneath the battery for damage.

I have the 2000 Cadillac Catera Sport and I had the same problem. ABS, TC light and no speedometer and odo. I thought it was an electrical problem however I solved the problem by refurbishing the ABS Module. If you bring to the dealer it will cost you $3,000. You can have your ABS module rebuilt try modulemaster.com they do it for about $200 I believe. I got mine fixed because a friend of mine removed them and soldered some loose connectors together. All it cost me was a case of beer! It worked for my car just a suggestion for you guys. My ABS Module was a Bosch 5.3. Hope this helps!

It's your ETCBM ( Electronic Traction Control Brake Module ). Had the same problem . This will cause your speedometer , ABS brakes and check engine light to come on.You'll even notice your stering is a little stif. I had my mechanic remove it and sent it out to Module Masters for rebuild ( 5 year warranty ) Works like a charm now. Those guys are really great .Cost me with freight $160 plus mechanic to R & R it.
I found this info online . Most mechanics will say it is a Speed sensor, but after many hours and going that route you'll see what I mean.
PS: You can still drive the car ( carefully ) while you wait for the rebuilt unit to be returned.
