- The Cruise Control Circuit is somewhat simple, but without knowing how it works, it is hard to troubleshoot. This video goes over where the pin locations are as well as what are common problems with the system.

Thanks much! I’m trouble shooting this issue now on my bus.
Thanks for the video! Made my search easier
3406E my cruise cuts off while driving ..and takes its' time to work again.
Great videos, thanks for all the knowledge. My 1998 379 cruise works when it wants to, no particular time or reason. Any guidance would be appreciated, the switches were replaced no help, Jake works fine.
Thank you for explaining the return circuit! I was thinking it was a ground like the high idle switch in this medium duty mutt 3126 im working on
nice video.
Ape. You have a great videos. I have one question for you. Where the 387 2005 with cat c15. Has the brake switch?
good teachin
love the videos!
+Tina Comfort Thank You.
I have a 2001 peterbilt I do not have on off switch . 7cz with a brake save. I was told it is a brake pressure switch but the tech could not tell me where it was located. He had a rough idea but that was it. Any clue where it could be located
How do we install cruise control on our Cat 3116 motors? They both have air throttles and are mechanical.
Thanks!
Jeremy
Great video. One question, I have 12v at my #59 pin (ecm side) while Ecm connector not connected. We did have batt/master issues. Kinda thinking the ecm got arc damage. What you think?
I have an 02 379 with a 6NZ Cat. My high idle works but I cannot get the truck to cruise. The clutch will also turn the jakes off. Any help? I have also replaced both switches in the dash
I got a strange situation. I can set it in neutral and it shuts off when I apply the brake pedal. It won't set in drive at highway speeds.....
why doesn't my cruise light on the dasboard not come on? have replaced the on/off switch. The test light doe's come on. CAT ET says its the brake pressure sensor switch which we have replaced with a new one.
it also works with pto
I'm guessing my issue is a bad switch. 05 379 with a BXS. Cruise, high idle, and flash codes won't work. Jake's work and the check engine light is not burnt out, the light for the cruise control lights up when you flip the switch on, and the brake lights function as they should. I have had intermittent issues with both the tach and speedometer needles hoping around, or occasionally getting stuck and not moving at all, but the cruise and high idle still worked fine until last night. Any thoughts, Ape, or others?
Have you ever installed a cruise control on a 3406 b?? 3zj to be more specific. If so where did you find the cruise control or where would you recommend getting one? Thanks
Hey man, love your videos!! just got a quick question for you. I'm currently working on getting my associate degree in diesel technology and am interested in working as a mechanic for cat. how long would the training be at the dealership even after getting my degree? would I still have to do the 2 year think big program?
+Joe Joe That really depends on the department you work for. Some places will put you on as a mechanic some as an apprentice. Every shop is different in their mentality and how management sees new guys coming out of school. Not every Dealer has the ThinkBig and if you already have a degree they probably wouldn't put you in another program.
C7 sterling dump truck cannot get cruise control or hi idle to work checked with cat et and noticed the low speed cruise setting was 127mph I'm not sure if this could be the cause or if I'm looking in the wrong place
I liked the video I have a question for you I need the ecm diagram of the c15 bxs25148 if it is necessary to pay you for this just let me know thanks
Whats up Ape, got a few questions for ya if ya don't mind please and you may have answered them before but Idk. Fist off, in your opinion what is the best 3406 engine to have and run in a semi?? Next one is I've heard and see that Cat used two different types od pistons in those engines, A 1 piece and a 2 piece, Why is that and which is better to have?? Next thing is are you a member on the Cat engine masters group on facebook?? Thanks for the vids and keep them coming dude, Learning a bit about diagnosing and repairing and hope to use this knowledge to fix my own someday.
+Gary ClarkII I would have to say any of the single turbo C-15 engines really, the 6NZ and 1LW are pretty hard to beat. The older 3406E engines are very good too, just have a worse oil pan gasket design and a couple other little things. Cat used a bunch of different 1 piece and 2 piece piston designs throughout the years, but I couldn't tell you which one is better. The piston part number is based on the engine serial number and horsepower range, I would just recommend going with what Cat recommends. Cat had very few problems with their pistons over the years, it was more the valvetrain that failed more often. I don't have a Facebook.
I know you're a busy man but if you could help it would be great ,how could you hot wire the cruise with no switches except the on -off and set resume ,run grounds to ecm on pin locations or power?
Question I lost my cruise control on 387 peterbilt with a c-15 nxs .I do show open on service brake switch #1 on cat-et I just can't find that switch any idea were I can find it?
Oh shoot, I wish you had a 40 pin schematic... 1997 Ford LTL9000 with a 5EK engine
+Gregory A. Parsons You need the pin numbers on your 5EK? What is the entire serial number?
Hi Ape...5EK80175 this is a dump truck, was bought well used. When I first got the truck about 1.5 years ago I used the cruise control to check engine codes, so it did work awhile ago, now nothing..
+Gregory A. Parsons Alright cruise on/off is pin 20 set is pin 25 and resume is 15. Hope that helps.
+Gregory A. Parsons Oh the sensor common is pin 29.
Ok Thanx, checking and matching my Ford schematic pin #
14=brake
15=resume
20=on/off
25=set
29=common to others also
31=clutch
35=throttle...?
37=throttle..?
this really helped because Ford overlays their wiring diagram with 3 other engine that could also have been used, so this narrowed it down by following your starting numbers you provided for a Cat engine.. if my above numbers are correct...
2007 387 c15
What better way to find out about issues then to ask a bunch of peterbilt owners these questions right.
Hi every one so im sure many of you have experienced issues with cruise control not engaging freeway speed, so what could be the issue?
Engine break works and rpm idle engages, both buttons on dash have been replaced. The clutch button has been replaced, what else could it be? Thanks ahead of time.
ramseygonzalez75 make sure your clutch pedal is coming all the way up
Greg, you might check BbB industries. com or Google it. They have car and truck wiring diagrams. I'm unsure if they have what you are looking for.
Thanx... Bought a Ford schematic for the proper year and model truck... Just haven't studied enough to look at the Cat pin in numbers to computer.. Used it for more on headlight wiring
DOES ANYBODY KNOW A TH-cam CHANNEL LIKE THIS ABOUT THE SERIES 60 DETROIT...???
Suburb video as usual. We don't have CAT ET, but we used to, so currently I utilize blink codes and support from Peterson CAT in KF for troubleshooting purposes. But I'll ask you, and other people can learn about this particular issue. We run 11 KW T800's (1996 - 2002); however, in one truck the blink code system doesn't function, but the cruise control does. Any thoughts?
+Chad Jessup Hmmmmm, the cruise set and resume works, but the blink codes don't? Sounds like the ECM is perhaps malfunctioned or the check engine light is burned out perhaps. I haven't actually seen that before.
The check engine light is good.
The truck arrived at the yard with the check engine light illuminated, and that is when I discovered the blink code system wasn't working. I took a guess that the problem was low coolant, which it was - sometimes it is better to be lucky than good.
+Chad Jessup I would say it is always better to get lucky than be good. Now back to talking about mechanic related items, there is always a bit of luck doing troubleshooting anyways, since you usually have to pick a path to go down and that is half the time up to a hunch you have.
