In this video I have a look at a customers 2009 Jeep Grand Cherokee that has a customer complaint that the tachometer and speedometer cut out and drop to zero then turn right back on. It has a lot of “U” codes in it for an issue on the CAN B data bus. Let’s have a look and see what we can figure out.
-Enjoy!

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.

I liked the vid i never learned this technical stuff to good on vehicles it definitely hurt me later. A friend has 2016 Promaster nobody can fix been to 16 shops I think plus

Good ol' Important connectors right next to a battery. A Chrysler Classic!
thats not a male pin. you cannot assume its gender.
how many ice scrapers does a person need?
lovely. 93k and its fucked. for a chrysler thats 60k past its life expectancy……..
You are like the Sherlock Holmes of automotive electronics issues and problems. It is cool to watch you figure these things out.
Who would buy a used battery from a junk yard?
'…female half…' watch it buddy!
The other day a waitress plonked down a soda refill on her way past the table, before I was completely done my first one, and without being asked. I called after her, 'You are a prince.' Ah… quickly amended it to princess. 'Oops, sorry, princess you're a princess'. Quick as a wink she spun a 180, came a step back, and said with a smile, 'Did you just misgender me?' It was pretty funny, the table had a good laugh, and nice to see not everyone has gone off the deep end. Our table was Boomers and she was late 20s ish.
Having an 07 Jeep GC, I find this very useful!!
I never put anything together dry. CorBan, grease or anti-seize for mating surfaces/attach hardware and dielectric for electrical connectors.
