Cruise Control Light

I second calling ACS. They repaired my ECM.

Side note: For as many times as ACS has been mentioned on here, the site should could a kick back for referring business. I mean since we are trying to generate funds for the site. Just sayin...lol!

You can remove those switches and replace them. Might be able to spray contact cleaner in them as well.

Rock auto has them. BWD as I remember, same as the OE.

Well, I'll spare you all the details, but the third ECM was the charm.  This one was a remanufactured Cummins ECM, installed and programmed by Cummins in Grand Junction.  I now have a much lighter pocket book, but I have cruise control!  Thanks for 4 years of help!

Good to hear that all is working again. How much lighter is your wallet?

Well, those three days were amazing.  Truck died this morning.  Codes 0215 and 1689 joined the party.

Check your alternator before replacing the VP44. I would hate to see you ruin another VP44 with a bad alternator and possible AC noise issue.

Picked up my truck with the new ecm.  It had 5 new codes and the abs and brake light were on.   After having the techs look at it for a while, I ended up taking the truck to Napa, disconnecting the batteries, and installing a new alternator.  The codes all went away.  Drive it 100 miles and the abs and brake light flickered a lot and then stayed on but no more codes.  I asked tech after tech about the alternator output and “ac noise” they acted like they never heard of it and said “it’s putting out good voltage” but it sure looks like you were right to be suspicious of the alternator.  Now on to figuring out the abs light and possibly replacing the battery cables as I don’t like how corroded they are.  Hopefully this ecm will last.

It would be a good idea to check the new alternator for AC voltage. They can have too much right out of the box. Maybe not enough to show up short term but can still cause harm.
