’09 Jeep Grand Cherokee – Tach & Speedometer Cut Out

I know it seems there is a lot of talking in this video but that is how the cookie crumbles with a lot of diags. First you have to duplicate the customers problem, learn and understand code set criteria and system operation, identify and locate system components, plan the work then work the plan. The majority of that time is spent in front of a screen to be honest. After that you carry out your tests and analyze the results either solving the problem or using that gathered data to come with another set of tests. It's boring to most but it the only efficient way to problem solve. Sure you could rip and tear and get lucky once in a while but I think this is a pretty solid approach. Hope it helps.

As much as i want to leave my work at work, I'm always thinking about cars I'm working on or future jobs. I see we are similar in that nature but your a legend my guy. Your teaching me more than 2 years of tech school could. Keep doing what your doing but only if it makes you happy.

There IS a lot of talking, yes, but this is classroom stuff not an action adventure movie. If I had a shop teacher like you in high school I would have been a mechanic instead of a carpenter. Thanks for sharing the knowledge Eric!

You’re the man!

Eric shows WHY you shouldn't weep & moan IF your tech fixes your problem(s)- and you get a hefty bill– do you think you have twenty years of book,online and on the job experience? You don't.And then you have to get an idea of what the Operating Expenses are for a shop that can handle just about anything you push pull or drive in.
IT"S outrageous,ask an owner operator

i've only seen standard crescent wrenches. where can i get one those metric ones you speak of? 😂

Sweet …

So the repair fix is for members only. ok thank you.

Part two is for members only ?? 🙁

Excellent video and diagnosis Eric. I love these who done it movies.

Only a little bit into the video, so sorry if you go this way (you're currently talking about going through the modules to find one to unplug). Many Oscilloscopes these days have CANBUS decoding (turns the CANBUS signal into text/data) . If your software has it available, you might have learned something by decoding the message where the differential signal is incorrect(the oscilloscope only needs 1 side of the signal to decode it), looking up the ID code, and seeing if you can find something in common between them all, then identify the module sending a 'bad' signal that way.

Perhaps useful to look into whether your equipment does this!

I like your videos but the background noise makes them unwatchable. I understand that it's a working garage, but film the videos out of hours.

My question is why is it that all of these auto makers put these modules underneath the hoods next to the battery where they know they’re gonna be all messed up from the battery off gassing we’re getting full of moisture from being underneath the hood as well especially in your area, their New York Seems to me there must be a better place to put them inside the cabin area, then underneath the hood next to the battery.

You need to get on the ALLDATA train, my friend.
