Freightliner cascadia CPC4 failure internal inspection shortage high prices problems how to fix it

[@Endar13]

CPC survivor here. He is absolutely right about diagnosing other issues. Most mechanics plug their laptops and see a bunch of CPC codes and are quick to say it's the CPC which is what happened in my case. Turns out all the codes that I had were being set off by sensors on the same wiring harness. This was before the back order issue so I went through 2 CPC's till we figured that out. Have your mechanics try out your supposed bad CPC on another Cascadia before anything.

[@shaunyb2343]

First thing you do when diag a cpc issue you should connect to truck and if you cannot connect to cpc you should check diagnostics 9 pin connector for battery voltage and ground if that checks out then check 1939 + which should be 2.6v and 1939 - which should be 2.3 if that checks out then remove the negative battery cable and set multi meter to resistance and test 1939 + and 1939 - resistance value should be 60 ohms . If that checks out check for power ground and signal at cpc and then remove the battery negative and check 1939 wires for resistance 60 ohms . J1939 250k system has green and yellow 1939 wires . J1939 500k system wires are white with green strip and white with yellow strip

Can't help on this one but other back orders message me and we can probably help. We are usually ahead of the curve on stock before the shortages. Except we didn't charge people $2500 for a $600 water pump or a $700 DEF Pump.

[@pete8751]

The problem is probably in, or rather under, the big square chip. That is what we call a "ball grid array" package. It has no leads, but underneath is a square matrix of gold pads, each with a tiny ball of solder, located over a matching array of pads that connect it to the PCB. The chip is soldered in place in an oven, which melts all of the solder balls at once (at the same time as all the other solder joints on the board). Unfortunately, after a few years of vibration some of those ball connections can crack, and because they are under the chip, you cannot inspect them or rework them without special equipment. These boards can be inspected by X-Ray, which reveals any broken connections. A very well equipped shop will have an X-Ray machine, and further equipment to remove and replace the chip, but we are talking about a capital investment well over $100k, so your local garage repair ship won't have it.

[@larrymendoza759]

You're right. I took mine too an electronic repair shop and the guy said everything you just said. He also said everything tested good and if anything its gonna be that big chip but he also said alot of times they cannot be fixed. Do you think he said that because he doesnt have the right equipment

[@pete8751]

@@larrymendoza759 Almost certainly, yes. I have a couple of ECMs here in my shop and I don't have the equipment to fix them or even diagnose them. That chip has an incredible 416 connection pads underneath it in a square matrix. Two things I might try - either work the chip over with a hot air gun to remelt the solder balls, or else strip the battery and meltable plastic connectors off the board and send it through the reflow oven. Either may well write it off permanently.

I found 2 placed in Chicago land that are repairing CPC's. Price is high, but that's just supply and demand economics. I feel better paying someone to repair my CPC then contribute to people stealing them more. MMFiX in Arlington Heights, IL and AVI Electronics in Palatine, IL that are fixing them. Can find them on Google Maps. One of our friends companies used them for 2 already and they say they work great and are brick and mortar stores MMFiX is 2500 or 2900 for 20-25 days or 5-7 days turn around time. Cash or Zelle only. 1 year warranty. AVI is 2500 or 4500 for 21-28 days or 3-5 days turn around time. They also take CC for a 3% fee. 3 year warranty.

First thing I was wondering was if that battery on the board was still good. Did you happen to check it with a voltmeter? If it's bad, it couldn't hurt to replace it. Doubt if it would fix it but I've heard of weirder things being the problem. Also check the solder joints coming from the board to the connectors. Surface mount electronics are replaceable and can be diagnosed and repaired/replaced- you need hot air soldering/reflow equipment, but it's not something that anyone can do, requires specific techniques and knowledge. Sometimes it's relatively easy though, like the "ring of death" on the Xbox 360's. Their surface mount chips would become loose after enough thermal cycles and they could be fixed by simply heating the board enough to re-melt the solder and make the connections good again. But you have to be careful, use just enough heat to melt the solder but not too much where you damage the chips. If those boards are bad, you don't have much to loose by asking an electronics friend to "reflow the chips" and see if it fixes it. If you want to try an even simpler technique, you could try putting the whole board in an oven at 500 degrees for a half hour or so. I'm not kidding. Of course first you're going to need to take it out of its plastic enclosure box, take any of the plastic connectors off, take the battery off (it will explode at those temps) and set it on something like a cookie sheet. Let it "cook" for a half hour at that temp, then turn the oven off, but DON'T take it out or even touch/jiggle it while it's hot, let the oven cool down all the way before you take it out again. Worst that could happen is it still won't work. Of course that lacquer coating on the board might start smoking and even catch fire, keep an eye on it and abort the mission if it looks like it's going to catch fire. Look at it this way- If it doesn't work, you wasted an hour of time. If it DOES work, you saved thousands of dollars and will be a hero!

I used to do XBOX 360 RROD and E46 repairs years ago. Over 2500 consoles fixed in a year. I was turning out 8-10 consoles a day. Even microsoft was giving people my contact info for years. I hope its as easy as a reflow, I know I'll be trying that method if my CPC goes out. Like you said, worse thing that can happen is it still dont work.

[@RichTheNoun]

@@WORM1100 it would be cool if you could get Francisco to send you a couple and see if the technique works on them. Think the lacquer coating would be a problem though?

I have a 2014 Freightliner Cascadia. I parked it on Friday. It had no issues at all. I started it on Monday with no issues but after it warmed up and I tried to move, the accelerator is not responding at all. I thought the pedal had died. I got my mechanic to come and scan it. He said it is the CPC. I went to the local Freightliner and they told me it cost about $1,500 and I have to return the old one. They said that they don't have it in stock and I have to wait 2 weeks. After 2 weeks, I was told I have to wait at least 60 days before I can get it. A friend of mine who is an automotive electrician called a friend of his who is a mobile truck electrician. The guy said send me a picture of the CPC and when we did, he said that he has it and will come in an hour. I already pulled out the old one by the time he arrived and he plugged the used one and reprogrammed it. That was around the end of August, 2021. So far, I have no issues other than holding my breath. These CPCs can go anytime without warning and there is no place you can get a new one. Freightliner doesn't care about it.

Our issue was no crank, voltage gauge not working, Def showing red or empty when it was full. I ordered a bew one from freightliner but kept my old cpc4. After many months i havent received the new cpc so i sent my old cpc4 to Curcuit board medics in South Carolina. They fixed it and i got the express package. I wish i hadn't waited so long trusting freightliner . They dint have them and they have no clue when i will get the new one.. So dont let go of your old coc and have it repaired.

First and foremost make sure you don't have a simple fuel or air filter that got clogged. Even if it was just a month ago changed. Next easy common failure for power on Cascadia/DD15 is the Delta P Sensor. Takes 15 mins to change. After do a Fuel Pressure (Bar) Test and Cylinder Compression Test. Check your tanks and fuel filters for metal shavings. Could be also a fuel pump starting to fail.
