Diagnostic and training approach ; Mack Trucks

Martin Owner/Technician Brooklyn, New York Posted   Latest   Edited  

Good day,

I trust everyone is keeping good and safe. I was called in to do some basic electrical training for a local construction company and also introduce a diagnostic scanner the same company recently purchased. That went well enough but now the offer has extended to consultancy on the repair/maintenance of a few Mack cement trucks. Mack is pretty much new to me but what I can seen is a mismatch of electrical parts and components with a "keep your finger crossed" approach. All the engines are Mack III generation CV700 models, no Cummins. There is no service history data and honestly the trucks are in a mess with driveability issues. Short of the diagnostic scanner I have no other Mack specific manuals or resources. I reckon it will take some back and forth so I can be emailed directly as well. Thanks in advance.

Your best bang for the buck would be a subscription to TruckFaultCodes. You can try a premium membership for $10 for 7 days. A yearly subscription is only $200. You will have access to code information, OEM diagnostic flow charts, and wiring diagrams. Just be careful with Mack (or any truck OE for that matter), their flow charts can load the parts shotgun up quickly. I recommend using their flow…

Hey matt i just started at a diesel shop. Ford, chevy, dodge. Is there a lot of flashing on these. I read your post so i asume aftermarket is better on ford. What about chevy and dodge? I want to get my lsid and start with rap to begin. Later move to doing it myself until i learn more. Any suggestions

You will still want IDS for Ford. The new VCM from Ford is supposed to work for GM too, so you could buy one piece of hardware for both. FCA is a whole other story, WiTech is an expensive investment, but necessary. LSID is a must for newer FCA, no way around it right now.

One other thing, the medium duty GM require a separate subscription to GDS, and you need to buy the LD version in order to buy the MD. LMK if you need further guidance, happy to have a phone call or Zoom meeting with you.

Yes. Look thru the OEM website selection. This is the gateway to GM acdelcotds​.​com/subscriptions Not a BowTie guy so I can't give any help on using the site. Ford links you to the this site motorcraftservice​.​com I used it a few months ago. Needed wiring info on a F750. 72 hour access, their minimum was less than $30.00. Did have to create an account. I thought it…
