Cruise Control on a Frieghtliner FS-65

great find!!!


the first diragram shows a 70 pin body-builder connector.. one can hope the wires are stubbed off at the body builder connector... Nav-star has the same connector and has optional featires stubbed off..

On this diagram there's just one set resume switch, as well as a fast idle switch/rpm control which a lot of buses seem to have.
The dash usually looks like this, minus the CC switches

im pretty sure the 3126 was before the Multiplex system that the C7s got.. so its discreet switches for cruise..

My fs 65 came factory with cruise so it should be as simple as getting the switches and enableing it in the ecu I am thinkin. Mine is an 03 model.

I am also highly interested in learning how to enable cruise. We have a 2002 Freightlier FS65 with a CAT 3126 in it. I have a login for Thomas Online, CAT, and Daimler's website. I can get all sorts of diagrams and such but I need to know what they are called by the respective manufacturers. I suppose I'll start poking around the sites a bit and see what I can discover.

So far, no luck. The Thomas site only shows what *MY* bus had on it when manufactured. The Freightliner site is not fully functional right now. I'll try again later.

theres 2 switches on that diagram.. there is set / resume then 2 lines below is a cruise on/off switch.. I dont have a program on this comouter to draw circles around but they are there..


whats missong are the notes.. I want to know what "Note A" is...

I guess that set resume is for the CC and there's no rpm/idle control on this diagram. Can you not download the pdf? The note is visible on it.

do the freightliners not use the set / resume switch for the high idle like the navistar does?


on navistar you turn cruise on in neutral and use the resume / accell button to run the idle up to where you want to keep it and it just holds till you hit the brakes

No, they have 4 separate switches, at least on the fs-65

I know that most computer savvy people won't like this?
On my all mechanical bus with a heavy return spring on the throttle I use a broom stick cut to full throttle length from the steel base rail chair and a rope that runs up to my hand/wrist on the the steering wheel?
I can release cruise buy putting my foot on the throttle and it knocks the cruise off or I can pull it out of cruise with the rope around my wrist?
I think it was SOMEWHEREINTHE USA that adapted a cruise control servo to his bus but there is one other that I can't remember right now that might have shared that?

[cadillackid]

I guess if I was running against the redline on my busses i would be able to use the stick method.. but I tend to build them so I no longer have to run against the redline.. .. the easiest place to mount a servo cruise is at the pedal itself on a mechanical or fly-by-wire diesel..

"Note A: This is an optional feature not installed on all vehicles."


It appears right below the color coding block on the second page.

Today, I went to the local Freightliner dealer to ask about adding cruise control to my bus. They were basically clueless. If it was not originally on the vehicle, they can not look it up because they use the VIN (last 6 characters) to look up the information about that particular build. While there, I called the Freightlier Custom Chassis 24-hour Help Desk (in Gafney, SC @ 800-385-4357) and they were using the same website that can access. They did say that if I can get the last six characters of a vehicle that has cruise control from the factory, then it can be looked up in PartsPro.


Sdferrell, would you mind giving me the last six characters of your VIN?

[EastCoastCB]

Yeah someone find out!

Good work here gang!

[cadillackid]

great work.. and yeah everything seems to be by VIN.. navistar is the same way. I had to use different VINs to download different calibrations for my engine computers..



hopefully its also not too hard to get the ECM parameters enabled for cruise.. its easy and a customer-modifiable parameter in navistar.. im trying to learn and figure out what software and parameters are required to enable / disable features on CAT... there is some discussions about it on mhhauto (a somewhat-extreme vehicle and vehicle electronics enthusiast site).. the newer CAT stuff is a lot tougher to update. but not sure about pre ACERT stuff yet..

That's the same problem I had. Use these digits it was an earlier Fs65 of the same vintage that did have CC. J29506

Thank you. I'll start researching it this evening while I watch a few NCAA tournament games.

Awesome. Please report back to us.

[Native]

As I suspected ... I can only pull up information for the VIN that I own. This means I will have to get Freightliner to do the research. More on this soon ...

Has anyone called a bus parts supplier? THey all seem to have "thomas freightliner cruise switches".
