cruise control by "Cruise Control"

[416Ford]

Looking for a manual to trouble shoot my cruise. Green ON light comes on but the ON/Increase light will not go on.

[416Ford]

I did check all my fuses and the ON button will beep if I hit it three times with the key on.

Is this the company?  ....Several manuals posted.

No. It's an add on unit for a non computer car. Simalar to the Rostra.

I assume you've checked Rostra.com. I have the WorldCruise2 which is sold by Rostra. If you go to Google and type in 250-1233form4565.pdf it will show the install manual and there is trouble shooting guide in the back starting on page 20. Hope this helps.

Dave, did you recently put LED taillights on the car? When I did, cruise stopped working.

Make sure the brake light circuit is working.

BINGO.
I bet that is it. I did install LED rear bulbs last fall. I have always had them in the front. I will check that tonight.

Thanks Tony.

Its interesting the minor problems that LED bulbs can cause on vehicles... On Ford trucks some years back. People swap out the standard bulbs or tail lights for LED stuff.

At the time Ford used some system that checked for resistance and power feed thru the tail light circuit for brake light application instead of a simple feed wire to the PCM from the brake pedal ..  The LED bulbs caused a change in the feedback the PCM looked for and then cancelled the torque converter lockup feature because the PCM thought the brake lights were "on" hence that meant the brakes were applied (not).

Of course , now the LED tail lights are common  and so is the theft of the LED tail lights , along with the  tail gates are still stolen often.

I have all led lights and my cruise would not work.  After talking to Dakota and Rostra the LED's won't produce enough ground at the brake light switch.
The fix is to install a relay from brake switch to the cruise control for ground.

Dave,  Sometimes it's just the little things

It was the bulb but I already had an LED flasher relay installed for the front LEDs. New non LED bulbs and I have cruise again.

Yes you need the LED flasher, but to get proper ground to the cruise, you need a relay from brake switch to cruise.
Hot side of brake switch to relay and ground to cruise ground, to give the cruise a good ground.
