Buzz or no buzz

I recently had a breakdown on vacation. Initially they told me my ICM was bad $1200. They changed it , no help. eventually they got to the problem being a mismatch between the filter element and cap after $3000. I never thought the module was bad but they told me it failed the buzz test. I had heard of a buzz test on a 7.3 so I figured OK. I have a lot of issues with the repair but mostly on the module. I was told yesterday by another mechanic that you can not do a buzz test on a 6.0 is this true? The shop that worked on it said after they changed it it passed the buzz test. I would appriciate any help.

On a 6.0, you can do an Injector Electrical self-test (buzz test) It is like a 7.3 test in that the thest will buzz all 8 injectors then walk thru each injector 1-8. It does it I believe about 3 times.

A lot of people don't think the 6.0 does a buzz test is because they can't hear it like they did on the 7.3. Those puppys ya could hear while sitting on the tailgate.

So if you can't hear it, what determines the results. They kept refering to not hearing it. Also I know I paid too much but when you are broke down 900 miles away from home and can't drive the truck, you're pretty much screwed and that is what I'm trying to determine. I don't like it when shops take advantage of people on vacation aqnd intend to take some action.

When you do a buzz test on a 6.0 it performs the test exactly like a 7.3 does, its just a LOT quieter. You usually gotta make sure the shop is quiet and stick your head out the window.

The buzz test is iniated by a scan tool that iss capable of doing so. The results are read from off the tool. The more sofisticated a scan tool the more results you will see.
