THis guy, Eric O and Ivan are my three favorite car repair channels. All three of these guys are brilliant.

There is no other way for me to say it without typing paragraphs. You are an absolute beast. Quick, methodical, the definition of "test, don't guess".

[@advancedleveldiagnostics]

Thanks!

[@craiggoodwin9704]

A very good basic diagnosis, but I especially appreciate and I bet you customer does too you follow-up and additional scan to confirm everything is fixed. Your tip on interpreting your scan tool at the end was the bonus bonus. Thanks for Sharing! 🙃🙂

[@advancedleveldiagnostics]

Thanks for watching!

[@rodvan-zeller6360]

The best part of the video was the follow up verifying the private network between ABS and SWM. On the diagram it showed two can lines which would make you think it is not a private network. Where did you get the 4 pin obd connector?

This video is timely. Like said above learning more and more from you and Eric, Ivan, Paul, et. I recently bought an 04 suburban from down south. Only code was a c0455 and a “service stability” on the info center. Looked up the factory service info pointing to the SWPS. Found out there is a 5 volt signal coming out of the sensor. Should be 2.5 with the wheel centered. Then goes to 0 fill left, and to 5 full right. Check with a meter and mine was at .25 at center. Any time you start it up and turn the wheel the “service stability” message would come back. After removing the sensor, which I broke the plastic taking it out unfortunately, I found it was turned to the left 1 turn already. I spun it 1 turn to the right and then it would read 2.5 at center like it was supposed to. Someone must have accidentally spun it when it was replaced in the past. Since I broke the housing removing it I replaced it again anyway. New one was 2.5 right away when installed. No more “service stability” message. Thanks again for sharing your experience!

[@advancedleveldiagnostics]

That's Awesome, Thanks for sharing!

[@frankcarpenetti5776]

You are one of my top three to watch when i can...great info. But if you can slow things down... just a bit....i know time is money.. but things are really , really fast here for people who are trying to learn from you. Please keep them coming as much as you can Bro!

[@jimpetty2961]

when hes onto it he gets fast 3x speed have to hit rewind lol.

[@salceti]

You can slow the playback speed down in the settings of the you tube videotape on the video window and you will see a settings gear up in the corner, selectbthat gear and a panel opens where you can select the playback speed

Having an issue on my 2010 Chevy Express where the Stabilitrak light will come on intermittently when hitting a pothole, typically goes away within a few seconds, seems more pronounced of an issue during high humidity or rain, same with a service airbag light. Recently replaced the under-hood fuse block/panel with an OEM new unit because I was having a crank but no start condition that I’m pretty sure was killing the signal to prime the fuel pump due to burnt circuitry within the old panel. Has been starting consistently since. Also routed a new ground strap from the engine to frame on the passenger front side. No other electrical related work besides that. Service airbag light would still intermittently flash prior to these repairs

[@mejalli911]

Awesome work man. I love ur work. Please keep making videos for us. Oh one small question. I didn't understand why u jumped the 2 data wires? Wouldn't that will damage the computer?

[@advancedleveldiagnostics]

I'm not really connecting them. I'm connecting CAN L to the output CAN L and CAN H from the input to CAN H of the output. So it just bypasses the Steering angle sensor.

[@iortac9490]

So you had comms from one module up to the the steering angle sensor then you confirmed it coming out the steering angle sensor. How were you able to verify it was reaching the other module before condemning the steering angle sensor? Thanks in advance

[@advancedleveldiagnostics]

I didn't verify if it was reaching the next module, because even if it wasn't this module should still work

[@iortac9490]

@@advancedleveldiagnostics sure i agree, but because you had comms in and comms out, what made you say the steering angle sensor is bad without first verifying comms reaching the other module? Thanks

[@GeneG-wk2mz]

I have 2013 Chevy express with same problem thanks

[@advancedleveldiagnostics]

Hope this helps!

[@AnointedRei]

Great video!! When you were testing for good communication in and out did you check that at the sensor or at the module? Thanks

[@advancedleveldiagnostics]

At the sensor. If the wire from the module was faulty, I wouldn't have a signal at the sensor with it unplugged.

[@MsFireboy2]

Thanks for posting. Question what’s the sampling rate of your O’scope?

[@advancedleveldiagnostics]

I think its 500MS/s

AI tells me that CF-33 toughbook was $3700 when it was new in 2017.. but there are several of them on fl333bay right now for less than $130.. Do you think I should grab one? or do you like your Latitude better? A quick video about these things would be cool.. Explaining what you like and don't like about them, etc. (and others- whatever else you have experience with). Just like you did about the little scope

[@advancedleveldiagnostics]

I like the cf-33 better then the latitude, I also just got a new one on ebay for $150😃. Just read through the description on the bottom because they all have some flaws, but alot of them are not a big deal.

[@calholli]

@@advancedleveldiagnostics Yeah.. I've been reading through them. I don't mind installing windows myself.. Might even throw linux on it, (maybe). I was just shocked at how cheat it is, only a few years old.

[@trublue2319]

[@Alex-Trejo]

Not to be rude. Can you slow down everything, especially when explaining and using the scanner.

[@salceti]

You can slow the playback speed down in the settings of the you tube videotape on the video window and you will see a settings gear up in the corner, selectbthat gear and a panel opens where you can select the playback speed

[@Alex-Trejo]

@@salceti Thanks for the tip👍

[@dude8165]

I cant see the screens. You need to improve your presentation little.

[@nicholassanza296]

Exactly it’s the same thing I was thinking watching this video. It was almost like he couldn’t sit still or tell us really what was going on and how he was doing it I do like his videos, but they need to be more presentable.
