What was the difference in the symptoms between the TCM going out versus the shifter going out?

[@shreqboi1]

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

[@shreqboi1]

Hope that helps

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

[@shreqboi1]

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

[@dayzinamerica]

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

[@shreqboi1]

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 🙏🏽

[@Alikhan-ln1tl]

I have the same issue now

[@shreqboi1]

Did you get it figured out?

[@meh-canics9628]

I am having similar issues!

[@shreqboi1]

Have you been able to figure them out?

[@meh-canics9628]

@ShreqBoi not yet, haven't got back to the truck yet. But it appears to be a CPC issue. Common apparently

[@JorgeGonzalez-ji6cz]

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.

[@shreqboi1]

Can you plug a laptop into it for diagnostics?

[@arnoldrotich3821]

Changed my CPC4 and it still came back? Did that happen to you

[@shreqboi1]

It didn’t happen to me. What is the truck doing?

[@mmfix3851]

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

[@MahA-pr7kr]

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]

You will need to connect a computer for diagnostics. Possibly a bad ABS sensor and a bad DEF pump

[@MahA-pr7kr]

@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]

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

[@MahA-pr7kr]

@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.

[@roundcornerent]

My older FL 70 is a hell of a lot more reliable then these new ones .. these new ones blow .

[@shreqboi1]

“They don’t make things like they used to” I completely agree, we have lots of computers and electronics to deal with now

[@bilalumar3898]

I got same issue yesterday

[@shreqboi1]

Did you end up figuring it out?

[@bilalumar3898]

@@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

[@damiansp1135]

In Cummins engine

[@shreqboi1]

I’m not too familiar with Cummins but as far as I know, they don’t have a CPC.

[@damiansp1135]
