Another F53 Cruise Control Post - Help!!

Ford stopped using vacuum operated cruise control awhile ago. If you do not have an electronic throttle body (throttle-by-wire) you probably have a standalone cruise control module.

First, is there 2 cables going to the throttle ? If yes, one is for the accelerator pedal and the other goes to the cruise control servo. It should look something like this.



The "smarts" are usually in a separate metal housed boxed mounted on the the left hand inner fender.

Hi Wizard! Thanks for taking the time to respond.

I have seen posts about that module, but I cannot find it. There is something similar looking to the right of my steering column (inside) that looked like it had a red reset button on top; maybe thats it? Ill take the seat out again and try to get a pic of it. ( not a lot of room for my frame to get a detailed pic). The pic may be delayed because we are heading out for our last trip of the year before we put her away for the winter.

I could not find a wiring diagram for an F53 chassis, but I did find one for an E450. On the cruise control servo, pin 7 Hot in Run. Pin 4 is Hot At All Time when the brake pedal is depressed. Pin 9 is Hot In Run when the the brake pedal is NOT depressed. Pin 10 is ground.

Likely one of these 2 is bad. They are not expensive in junk yards.

There is a third "shot in the dark". Around that time, Ford had an issue with fires caused by the brake pressure switch. This switch was a backup to the brake pedal switch (if both tail lights were not functioning, the CC could not tell you had stepped on the brake except for this backup). The "field service" fix was to install a short jumper with an inline fuse going to this brake pressure switch mounted under the master cylinder.
