BCM has nothing to do with it. The CCM - cruise control module receives input from the cruise control switch, free wiring diagrams here
http://www.bbbind.com/free-tsb enter vehicle info. under system click on engine, then under subsystem click speed control. Click the search button then the blue link.

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.

SOURCE: ABS and TC light on, speedometer and odometer not working

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!

SOURCE: my speedometer's not working neither is my cruise control

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.
www.modulemasters.com

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.

If all 3 lights don't come on, it's most likely the Brake light switch. Easy to get to- it rides against the pedal arm. This was a well known problem over the years, my 02' had not one but TWO recalls on it. Recall might be expired, contact a stealership...

Does brake light switch affect cruise control?


Yes. The brake light switch has to be in good condition because it is one way to disable the cruise when driving.

Have you recently had any brake work done? I had a 05' freestyle that did the same thing.. when you tap the brake the cruise kicks off right? so if your brake pedal is sticking or not returning fully to the up position, the cruise will immediately kick off like you applied the brake. Check to see if your brake lights are staying on when you release the brake. Let me know what happens, please and good luck.
