Cruise control engages then kicks it out immediately after. All brake lights work no codes or lights on on dash. Fuse is good.

Hello,

I would start by checking the codes because an input shaft speeds sensor can cause the cruise to kick out.

Here is a guide to help you get the codes:

Here is the cruise control wiring diagrams so you can see how the system works.

Check out the diagrams (below).

Please let us know what you find. We are interested to see what it is.

Cheers, Ken
