So far a better video on the TCM, I have a 2010 Mazda 5, before I buy the TCM I want to be sure it's the connection or the TCM. Because what's happening is, communication failure, but at some point it reconnect itself and smooth driving, I will park it, next day no communication, I will than touch a bit on the connector wires, somehow it returns to life, but not always the case...

Looks good for a 24 yo. Any tips from the owner?

Way to go.

Dude, you just save me time and effort tremendously. My 2004 corolla lost its check engine light and wont start, checked the EFI fuse as you described in this video and found out it did was busted. replaced the fuse and car starts at one click. thank you so much....new subscriber here. more power to you

Nice 👍🏼 one ! 👊🏼

My favorite sayin, “But it’s new”!

That's what you get when you buy Dora dong...(Duralast)

Worked on a lot of these over the years at Nissan. Don’t really think I’ve ever came across the fuel pressure too high issue tho. Our tests are quite stupid honestly. Either it’s the pump or harness/connector issue. It’s a quick and dirty test but unplugging the solenoid on the hp should cause the solenoid to revert back to bypass and the pressure should drop to around whatever the low side pressure is not really a sound testing method but it’s a quick way to find out if your mechanically screwed

How do make money cheap junk

What is the part number for the Kia Tension Gauge?

Where get to las cope?

God damn 🫣🫡 these diags are so satisfying to watch

Link to buy that mini scope? That would be handy

The drop-off in quality parts is crazy. Good catch

Pin 5 in the dlc terminates at G103, the ground for the cluster also terminates at G103...

Try 7 bad starters in a row 8th one was good 👍 lasted 3 months. I absolutely refuse to buy anything electric or electronically controlled from autozone. They should change their slogan to.. built not to last duracrap! I've had issues with sensors, control valves, alternators, starters, fuel pumps you name it! When you're a shop you have to be able to depend on the parts you buy! Time is money! The more time you spend changing crappy new parts the more it cost the shop

At 18:05. They replaced a valve, but they don't have AutoAuth to check codes!? Wtf? Why in the hell are they replacing parts on a system they can't access? 😂😅

The Duralast Gold NEW alternators are good. The rebuilds are from BBB Industries which is the same company that does all the house brand auto parts store rebuilds. Denso, ACDelco, Motorcraft and a few others are good rebuilds.

nice video. where did you get that 2 way lead for your scope?

Autozone is from the worst, seen many duralast alternators fail within days. I think its reman remy stuff, seen lots of issues with those too.

I’ve utilized Vantage GMM everyday for last 20 years..solid tool

That circuit tester is freaking awesome……..makes life easy to test circuits

Was it a reman or new alternator from autozone ? I have really good success with new alternators and starters from AZ. Both reman from AZ and orielly is a crap shoot but orielly rarely offers new units for anything.

Some 1999-2006 Silverado have 3 different alternator types. And then you got 1500, or 2500/2500HD, 3500/3500HD and each of those trims and models have different engines and then different alternators for different engines 😂 people buying parts just ask for whatever is cheapest. End up paying 2 times as more or even 3 like this guy here

The auto parts stores are saying F-U to us by buying crap and putting it into their own boxes. Buy from places like Rockauto online, where you know who made the part you're buying, and where you pay a lot less than Autozone charges for junk but you get a quality party. I routinely get name brand parts for 60% of what Autozone charges for crap like these broken alternators.

I got to the point where I have the store run a check on the alternator before I leave the store.

Gotta love them remans!!!

Thank you ❤❤❤❤

Great video, whether wrong or bad great diagnostic strategy!

Aftermarket parts can throw off diagnosing, I like OEM genuine parts

Damn, that would have driven me crazy! The LAST thing you suspect is that you put in a bad or wrong part!

AC Delco alternators and batteries is the way to go, especially on a chevy.

This is exactly why as a mobile mechanic I try to have the customer purchase quality parts and not buy house brand or remanufactured parts. This is also why I will not put a remanufactured alternator in a customers car anymore. I understand that sometimes the customers budget can dictate which parts they can afford, but it's usually not much more for a quality part or a new (non remanufactured) part. These days, people try to save a few dollars upfront and they end up spending way more on the back end.

Well the thing is those alternators presented in the video. Are remanufacured alternators. New alternators come painted in black or a silverish color. No matter what brand it is, the remanufactured alternators are a 50/50 shot of working. While the 100% new ones are more expensive, but always work

NEW = Never ever worked

Awesome as always THX

In the wiring diagram it said "2001 only" on the grey wire, so maybe the parts guys had the wrong alternator for that exact year. I'll bet those two bad devices are put right back on the shelf for the next customer. i was a little surprised you didn't pursue the bad cluster ground but it sounds like the customer will do that himself. Another eye opening video.

Cool video. Thanks for posting. I know it takes a lot to edit etc, but it'd be cool if you diag guys post more. Even "simple" diags, you might test or drop a sentence that makes it worth watching that you think is basic. I'd watch all the unedited boring diags.

Chinese keeping their promises to screw Americans

The prices of rebuild alternator’s are crazy you think they could at least work for a couple years . These are dead out of the box 🤷🏼‍♂️

I’m done with aftermarket parts. I went down a rabbit hole you wouldn’t believe after getting a bad idler pulley from oreily’s. I’m too embarrassed to even tell the story.

Gotta love the quality control on these parts.

Typical reman crap. If it was a NEW Duralast gold, it would be black.

You just got to love those Don'tlast alternators and starters.

One bad part is understandable, but two is inexcusable. Good job!

Finally. ALD let the customer work for themself! :D

The alternator is probably okay. The main issues with rebuilt alternators is that it probably has the wrong regulator. Sometimes it changes pin locations from year to year. Thanks again.

Nothing will throw you for a loop like when getting a bad part. It seems like it is happening more often these days. Nice job as usual!

Another Duralast piece of junk!

Don't buy AutoZone alternators. It would seem their supplier/rebuilder is not doing a good job - no quality control whatsoever. Good video.
