Just purchased a 2012 cxu613 pinnacle and noticed that the built in usb charger below the radio doesnt work, I have looked at some of the wiring diagrams but can't seem to figure out which fuse powers it. I checked the fuses under the panel on top of the dash and they are all good. thanks

Has anyone successfully completed the egr delete on the mack ac? My egr cooler is cracked and I am needing to delete it. Thanks for any and all help I have attempted to contact the op but he has been too busy to respond.

Just to update, I found the cause for my 8-4 code and it was in the wiring harness behind the oil filters, as TRH said "where people like to leave the f*#!;*# clamps off" 3 wires were rubbed nearly in to and grounded on the block. I for the life of me do not understand why people can't finish what they start, I mean come on people those clamps are there for a reason and not for looks...thanks to everybody who helped and guided me this is a great site with a lot of knowledgeable people who enjoy helping

I still can't find an answer for my check engine light, I have checked everything I know and see nothing, any and all help is greatly appreciated

Checked the pins and all is clean and dry, no corrosion and all looks good.

Are you referring to the engine ecm?

So about 3 weeks to a month ago I started getting a intermittent check engine light, but did not have a miss or loss of power, over the last couple of weeks truck seems to miss a little when idle and the light would come on after truck starts moving and stay on, the flash code is 8-4 Which if I am correct is eup #4 so I pulled it, checked wires for cut, broken, and rotted and replaced eup with new one, now engine runs the same and I still have check engine light so I'm at a loss as of what to do next. I have not had code entered into ecm yet but dont think that would cause light

Tuckers charge was ZERO and they were more than happy to help, service manager even called that sunday afternoon to make sure everything was fixed, unlimited minutes on cell phone so no extra charges there either, the way the service manager at tuckers explained it to me was that they were to small of a dealership to allow any customer to leave there unhappy and that one unhappy truck driver could do more damage to them on a cb radio than they could repair so why should they chance it and if mack of nashville couldn't afford to lose $500 in their shop that they probably aren't in good shape as a shop anyway

How would any of you feel if you took your car to a repair shop and at the end of the day when you went and picked it up they said sorry we didn't fix anything, we couldn't figure it out and by the way you owe us a grand for trying? Or better yet we have diagnosed your car as needing a complete overhaul but didn't do that and charged you 600 andate you found out you just needed a quart of oil? Nobody can honestly say they would be happy about it and if so your not being truthful! Yes I am angry yes I am frustrated and mainl u because I started going to the dealer to avoid this very issue with mechanics unfamiliar with mack and now it seems as if they do the same thing, he knew I was very upset when I paid that 600 and knew that was alot of money to me because we stood and taliked about it and even talked later on the cell phone about it, yes I think he is a good tech don't get me wrong because I do I just think he made a mistake as we all do and Instead of just telLing them he did either him or someone is trying to cover it up, I wish it wouldn't have happened and I would give anything if it hadn't or maybe if they hadn't acted the way they did about it but they did and somehow are trying to make it my fault that they didn't diagnosis it correctly and that chaps my ass!! Make a mistake and own it for GOD'S sake and let's move on, I have worked on trucks my entire life and have NEVER EVER done anything like this, if I ever made a mistake like this I always ate the labor period, why should you get paid for something done wrong? Anyways I have said enough about this and am sorry to have taken so much time up about this.....

84superdog, what I was saying about chicken shit is that instead of doing something so it wouldn't crank just say no and be done

Yes when first looked at apad it was flashing 4 red which is open circuit, after reseting it it blinked slow green which is normal, but to answer your question yes it showed code of 4 red

I really thought alot of the tech I spoke about till it came to this situation, Everyone makes mistakes and GOD willing I will make many more and I have no issues with others who make them, what I have issues with is the inability to acknowledge that you made one and own up to it, all this was is a simple misdiagnosis and actually I wanted my money credied towards future parts I didn't even want any actual Money to exchange hands,my understanding is that the apad system takes the high pressure switch and fan control away from the ecm and The apad controls it so by removing the apad system you are actually placing those controls back on the ecm therefore making the diagnosis wrong and that circuit in the ecm operated corectly, this is why he could not fix it with a flash of my ecm and also why my extra ecm allowed the fan to run as well

Sorry but I do have revenue and I am not mad at the world I just see the difference from 4ight and wrong

Yes I am aware that Mike is a member but it is what it is and I hate it had to come to this but that dealership and those involved were dishonest and as for the mack assist they offered to help resolve this issue and made n attempt to do so. All I ask for is to be honest with me and for them to return my money and all I got was a bunch of bull in return so I will never ever deal with them again, I'm not trying to offend anyone just telling the truth
