Multiple on/off, but not sure on the arming switch, could be momentary and the ECU does the hold or the switch does the hold.
Does your van have the controls on the stalk behind the wheel? All of those switches are momentary on my '08 GC. One "on/off" switch on the end, and then up/down/pull on the stalk to control the cruise. Similar to an older BMW, actually.

On one hand, that's a clever way to save pins and wires. On the other hand, there's something disturbingly '50s-ish about it and it means that your car's wires and connectors will have to be in tip-top shape to prevent your controls from going haywire.
It sounds like the system is failing a self test. To further diagnose I would need to ask questions which I know is useless.
four total dealer visits. The service tech was a jerk, but they finally got it fixed. In the end, the answer was clock spring. I paid $0 all-in, other than the $40 for the not-needed switch.

If I am understanding your description correctly, it works after a key cycle. So whatever module controls the cruise does its self check, the vehicle passes, then whatever the fault is shows up and the module shuts operation down. This is where it would be nice to scan it with a WiTech to see if there are any "switch short to ground" type history codes.
Kudos to logdog with the right internet diagnosis on the first reply.
Glad it's fixed. Those kind of issues are a pain on old stuff but livable. On a newer daily driver I HAVE to have them fixed or it's a downward spiral of not caring about little stuff after that.

Kudos indeed!! I didn't even read everything again to see. Amazing work!
