So the way we’ve been able to catch it is by plugging in our laptops and reading the codes. Either it gives us a code for the gear selector or we notice that our program doesn’t connect to the tcm. Another possible way might be by trying to engage the Jake brake and seeing if it will cycle through with the gear selector
Frist thank you for posting the video I got Freightliner DD15 with manual shift. I changed the Sam Cab fuse box and still having the problem so now I have try the CP4
Freightliner 2016, manual, no start no crank, def flashing.. Im thinking I have the same problem. Display is out so I can't see if the 2 lines flashing.
Hello. Have almost the same problem. Freightliner Cascadia 2016 Auto. The truck won't start the tractor's ABS light is on and the DEF light is red no check engine light. The dashboard screen does not show the transmission message and the screen just stuck with Underscore marks.
@shreqboi1 I hope not the CPC down because I replaced the CPC last year 🙏 I was trying to do something that may help I discount the battery cable red and black for 40 minutes to see if the lights go but nothing happened the same problem still. I sprayed the ABS wires and connectors using an electronic spray but the problem still did not go away.
@shreqboi1 @shreqboi1 Do you think there's a way I can start the engine? Because I was trying but no engine started. I can hear the crank starter working but no engine fires up I have a good battery I was also doing jumping cable but nothing happened but I'm sure the battery is good I just need to move my truck a little bit. By the way, The DEF tank has a little bit over one-quarter.
Cpc module. I have the same problem. . Mine is a 18 it went out before. It was that module before. It broke down in my parents yard. Today it happens again now I no what it is. Don't put air I'm the tank a waste of time. It this happens to u 95 percent it's that box. I will get me a spare
if the original cpc is programmed for automatic transmission and didnt crank the truck ,,, then u put a cpc from another truck that is programmed for manual transmission it will crank the truck but wont move it or throttle ... so make sure the shit controller in the transmission is working as it's not receiving air ... i had this issue today ... its all about that part and rare times its the shifter that you swapped
Correct, but I swapped two cpc from two different trucks with the same engine, transmission, both were 2016 and similar mileage. Thank you for your input 🙏🏽
I'm having a similar problem right now. The CPC4 module was stolen, they cut the wires. I reconnected the wires and bought a new module from the dealer. They programmed it. But the trac won't start because there is no communication with the transmission. The dashboard shows dashes where neutral should show. Checked all the fuses, wiring, everything's fine. What could be the problem? Is it that there's no air in the transmission?
@kushtoff yes this exactly what happened to me but before I change the $3400 part I let a mechanic check it on the computer ... sometimes it be the in cab Trans shifter ... I highly recommend a professional to check it on the computer as it will give him the exact code for the damage but 99% it's the shifter actuator that's attached on the transmission body
Im mobile. I do work at a shop Monday-Friday until 5pm. The shop is in Rialto, CA. You can find my number on my most recent videos on the lower left corner. Or on instagram @shreqboi
My truck doing the exact same thing…just brought a cpc for $2,000 will be putting it in tomorrow. Wish me luck
Hey bro what’s problem is CPC or ?
Thanks bro! It seems like Freightliner sent a single and killed all the trucks here lately
You’re welcome brotha. We were thinking the same! Thank you for the support 🙏🏽
What was the difference in the symptoms between the TCM going out versus the shifter going out?

Hope that helps

Can you plug a laptop into it for diagnostics?
Thanks man!!!!
No problem 🙏🏽
Changed my CPC4 and it still came back? Did that happen to you
It didn’t happen to me. What is the truck doing?
If is happen again you should buy legit cpc or repair yours first but if is happen again you have bad wire on J1939 data link
Hello.
Have almost the same problem.
Freightliner Cascadia 2016 Auto.
The truck won't start the tractor's ABS light is on and the DEF light is red
no check engine light.
The dashboard screen does not show the transmission message and the screen just stuck with Underscore marks.
You will need to connect a computer for diagnostics. Possibly a bad ABS sensor and a bad DEF pump

@@MahA-pr7kr check the DEF pump. If it’s full of crystallized DEF might be clogged, maybe a dirty filter

What’s your contact info??
Your phone number service please

I agree, I’ve heard they have a small battery inside that goes out on them. A good electronic repair guy should be able to fix them
Hello sir I have some problem I change shifter I change CPC not going out and RDN

where do you have your workshop or telephone

I am having similar issues!
Have you been able to figure them out?
@ShreqBoi not yet, haven't got back to the truck yet.
But it appears to be a CPC issue.
Common apparently
I have the same issue now
Did you get it figured out?
My older FL 70 is a hell of a lot more reliable then these new ones .. these new ones blow .
“They don’t make things like they used to” I completely agree, we have lots of computers and electronics to deal with now
I got same issue yesterday
Did you end up figuring it out?
@@shreqboi1 i think so bcoz ecm acm and cpc was not connecting to DDDL then took all 3 of em to the dealer to program the cpc
In Cummins engine
I’m not too familiar with Cummins but as far as I know, they don’t have a CPC.
@shreqboi1 thanks you
