Blinking Cruise Control Light

[Trukdiver]

I'm away from my FSM and computer. Does anyone know what a blinking cruise control light means? Continuous blinking. My cheapo bluetooth OBDII reader registers nothing. I was caught in standstill/creeping traffic when it started. Once the traffic let up, it still blinked continuously most of the time, but would occasionally stop for a a minute - then restart.

This is from the 80-series forum, but may apply: Cruise control blinking?

Post #23 seems to have some specific diagnosis info.

I've attached the Service Manual's Cruise Control diagnostics section if you're up for an exciting read...

I've been having a similar problem although my cruise control works fine.
It's just that the "Resume" function doesn't work at all.
It blinked at me on just one occasion when I was doing random things trying to see if I could get it to work properly, but since then, nothing.
Cruise works, Resume does not.
I've pretty much resigned myself to having to re-set it at the desired speed every time I need to tap the brakes.

I'm having a issue mine is engaging , but cuts out off and on while driving after a couple of minutes.Were a the fuses located.I'm thinking might be a speed sensor or brake light ?.Thanks.

OP here. Just an update on the blinking light. As I mentioned, I had been driving in standstill/creeping traffic for about an hour, but I didn't mention that it was a very wet day. I didn't drive through water, but it was just wet all around. I parked the car when I got home and the next day, it wouldn't start. Completely dead, even though the battery and alternator are brand new. I left it and went on vacation for 2 weeks. When I returned, I put it on the charger for a day and it started right up with no blinking cruise control light. I hope that's the end of the problem and that it was the wet conditions!

Hate to say it might not be. Most of those computers are inside the cabin. Sounds like you have a leak - check the windshield and sunroof drains.

Say it ain't so! I love it when I problem self-resolves. Grrr. Ok I'll check.

Checked my fuse no issue there I got a feeling might be break pedal or speed sensors what's the best way to check both of these ?.Thanks.

Any solution here? Mine blinks, no functionality. I've checked all fuses, followed FSM troubleshooting all the way back up the chain to the switch itself. All checks out.
