I understand why your in such demand. Not only do you have the skills, you have some really cool tools! Thanks for taking us along for the ride.

This diagnostic gig is a piece of cake when you watch Keith do it :) . 12 mins well invested. Great video once again Keith. Thanks

5 min to diagnose, 12 to shoot video. Show your appreciation everyone. Thanks pal

Great easy to follow steps! As an added note I have found over the years doing NATS 5 programming, to ensure it is a fully recognised key, try off/start/off +5 times as I have experienced a few over the years go into a valet mode whereby the key is good for 5 starts then locks out again!

Short and sweet so much packed in a couple of minutes.

At 3:30 you mention it could be a signal that could be still a failed key, this Maxima I'm working on has a signal from the key antenna (very fast waveform down in the microseconds) the NATS module then processes and sends out a signal very similar to what you have on your known good at the end of the video but still a crank with no injector pulse and security light on solid. There are small blueish burn marks in the PCM and codes from its self test that don't match what the scan tool reads but I'm either stuck in lock mode or have a bad key is all I can determine. Thanks for the video it got me much closer to an answer than where I was before with some terms I was able to search for and a better understanding of the system.

Excellent diagnosis.I have used that 5523 pin code on a Nissan Plusar here in Australia. Nissan Sentra in US

Great diagnostic video. Invaluable information. Thanks for taking time to teach us.

Man I just figured how to connect to my home TV and watch your video Man what a huge difference compared to watching on my phone lol Mind blogging what you do Nice to see a master at work

Your brilliant Keith... I may have to watch this one several times over for it to click so if you get like 500 views by tomorrow or so it will be mostly me. Thx as always for sharing and your time to do so.

Thank you so much for sharing, it's really helpful to have this information in your back pocket incase your sisters qx4 decides to not start. I really appreciate it, and I'm sure a ton of other people do too

at 3:15 when you check the communication line (orange wire) and it is 0 v hard to know if you have open wire or if any module is pulling down the voltage or the module responsible for producing the bias voltage the ecm or nats unit, at minute 9:00 we can compare with new unit when key on there is system voltage and any of the 2 modules is going to pull down the voltage when talking . very nice I am learning thanks for sharing .

Looks like I need a uscope I'm just getting comfortable with my Modis but it looks like you can get that little thing up and running in a hurry. Thanks for the video I just got a Launch so it's awesome that my launch should be able to do that service.

AWESOMENESS!

thanks keith always great to get quik diagnostic and repair.... i have been learning alot from all of you guys out here doing this .... it has stepped up my game alot on my thought prosess and how i look at things ... thanks once again

Thank you Keith. Good job. Great video. I always appreciate your videos. Have a good night.

Keith thank you so much for using the U-scope and the immobilizer gadget. I have both items but glad to see everything being used. Really appreciate all your videos. You need Rocco there to give you a hand. Thanks again. ❤️

we really appreciate the lessons from the master.

Awesome video & diag thanks for sharing.

You're a freakin' wizard! Thanks for the video.

No thumbs down Keith, finally!

Two great tools! Thanks!

Awesome makes me want to have a launch even more knowing it can handle stuff like that.

Man that is a nice scan tool you got! Thanks for telling me about it! Oh and good video!

nice job mate

Gracias por tu ayuda my friend

You are Truly Bad Ass

Thanks for NUTS video.

Thank you Keith for sharing

Very good Keith,by the way last night coming out of Atg training Kris lewis ask me to tell you,they still don't have a teacher in Staten island,interested

Saved me again!

Awesome content! I am diagnosing the same issue on a 01 maxima. voltage is good on my orange wire but no data packets when key is turned on. intermittent crank no start.

Great video

Hey I have a 2001 Nissan Sentra with the nats on it and I have the crank no start issue just like this . The light stays on in the dash when key is on. I was told The key is transponding so would I most likely just need a new immobilizer ? Thank you

I know you use many different scan tools, including this Launch. I work on older 1998-2008 Mercedes. I can buy a blue box for 2k. If that's the best, I am willing to. But if there is something available which is ALMOST as good for less, I would like to know your opinion. If I could find a genuine star C3 or C4, I would, but they're hard to find. Your thoughts please. Thank you Keith. (This is my side gig currently.)

Good work

Hello I need your help on this one, I replace ignition cylinder with the key then when I try to program my modus scanner wouldn’t give me the access, what would you recommend me and there is P1610 code can’t be clear.

Thanks for the great video Keith. Are you happy with the Uscope so far? The reviews I've read about them said they have issues charging the battery.

You said the cigarette adapter for the test leads were from AESWAVE but i couldnt find it on their website do you know what they call it or part number? Thanks

Thanks keith good info there. I remember searching for that nissan nats section every where on the launch before i figures its under maintenance.also you. An go to reset under immo reset to do the same

Hey Keith, is that a brand new OTC test light with red lead and needle point tip I saw in your van today?... : )

Great stuff. I see you're putting that scope to work. Is that component the weak point in most security systems?

Thank you for the info.

Get yourself the BNC female to MCX male connector for the uscope. 👍

Awesome

i have a similar issue. i have a P0227 Throttle/Pedal Position Sensor/Switch C Circuit Low Input and P1612 NATS Malfunction Pending codes and i replaced the throttle body and accelerator pedal. i'm thinking i've gotta replace the ecu now :(

I haven't used my launch on any Nissan's as yet but I did let a guy I know use it to do a new key for his Patrol & he was going on about having to get the serial number from the module(reader) & going to some website to get the pin?! I now wonder if he did it 'wrong' (the hard way)?! 😅

I have a Patrol Y61 with this NATS system. I can’t communicate with NATS. Is the actual communication happening with this module or is the communication with a virtual module integrated in the ECM ?

that imobilizer ring tool is extremely helpful and doesnt cost to much. when it comes to reading the data line with a scope do you have experience decoding it what it actually means?? i have never just scope it all the time.

What is your Launch tool model ? seems your tool can reprogram the key BCM ?

that "looks" so easy thank you for taking the time do you like the launch?

hey Keith, is there a way to check what nats version the vehicle might have without having the car available? I'm in the research phase for a 1997 infinity q45 Cima crank no start immo problem. I'm going to the shop that the vehicle is at for another vehicle, they asked me to take a look at it... not even sure I can do any immo work with my scan current tools. I only have a snap on verus, a thinktool proS and an autel 906bt... I also have a cardaq 3+ but I don't hold any subscriptions... I don't do immo work but I figured I'd give it a try

What scope is that and part number plesse . I'm impressed I see you use it all the time thank you great diagnosis

nice video, wonder if the programmer will do NATS 2 of my 1999 Infiniti I30. what model is the Launch you were using? Thanks

Great video Keith. Instead of buying that very expensive tester wouldn't a amp clamp in front of the key pick up the induction signal from the nats module?

AMD yiur little buddy you used to see if the LED LIGHT lights up when turning the key. Where can I get one and part number if you have. Thanks.

I have a 2001 Altima with the same problem. It's literally the same car except for some different cosmetics. Where can I take my car to have it fixed. Or can a locksmith do what you did in this video... Please advise.................

Hey Keith what wiring diagram are using their? I’m assuming it’s not from Identifix.

From the thumbnail,I thought you’re teaching us about a secret government space program from 2001 called Infinity. 😁 Now I’m disappointed. 🤣 👍👍👍

Whats the name of the oscilloscope???

Is that a scope protector/case? Where did you get it? AES?

Una. Pregunta. Amigo. Donde. Conpraste. Esa. Eramieta. Discupa la. Pregunta grasia

i think kieths found a new favorite toy what did you do without it all these years?

When the tool asks u 14 pin 16 pin, how do u determine what that is?

Does snap on scanners like verus have immobilizer initialization for nissan also and other cars?

hey keith have you thought of getting something like a head mount cam?

My Car Doing this Samething I Have A 2001 Maxima

Ok. Y. Ke. Usaste. Para. La. Antena

My 2002 Infiniti won't show codes

What make is that orange scope where do I get one
