I have an Autel 906BT bidirectional scan tool. Will Leafspy give any more information then that can? I generally dislike an app based diagnostic product vs. a dedicated scan tool.
Please define the Leaf diagnostic functions of Autel 906BT, e.g. read/reset fault codes, change ECUs' modes, etc.I have an Autel 906BT bidirectional scan tool. Will Leafspy give any more information then that can? I generally dislike an app based diagnostic product vs. a dedicated scan tool.
Yes read/reset fault codes. Don't know what you mean by change ECUs' modes. That's why I'm asking.Please define the Leaf diagnostic functions of Autel 906BT, e.g. read/reset fault codes, change ECUs' modes, etc.
Are you guessing, or do you actually have the Autel and used it? If so, then tell us what you have done with it on your Leaf.Yes read/reset fault codes. Don't know what you mean by change ECUs' modes. That's why I'm asking.
Says he does.I have an Autel 906BT bidirectional scan tool.
Really? Are you guessing too? Have you used the Autel on a Leaf? Furthermore, It sounds like you don't fully understand the functionally of LeafSpy.I think your Autel will be able to do more, but may not lay out the info in a way to easily read it as Leafspy. Both receive the exact same info on the Can Bus.
I tend to agree with your thinking.
One big problem with the Leaf (and I would guess all purely EV's) is they don't have to comply with the OBD2 protocol so you can never be sure what can and cannot be done unless you buy the tool and try. While the Leaf has an "OBD2" "port", it will not work with many tools that are built for OBD2 access.
Neither Autel nor Leafspy "acess" the info directly, they only can report what the cars internal stuff is reporting to each other on the CAN BUS.
Some of the more expensive diagnostic scanners/ tools can reset things like brake 0 travel and steering etc, things that I don't believe Leafspy can. Some can match new TPS senders to the car and other functions.
The thing Leafspy does well is lay the info out in graphs in a way it is easy to look at, like cell balance, for example. The info is still available on a scanner it just might not be graphed as nicely.
If you have or work on other cars, a good versatile scan tool that is compatible with more cars, in my view, would be better than one that can only work on the Leaf. That said, if you have a smart phone that can download the app, all you need is a dongle to connect, so around $35 or so to have both types. If you have to buy a smart phone to download, and you already have the Autel, I wouldn't think it would be worth it. Just depends on how much your Autel can do.
That is what i've discovered also with the Mitsubishi. They have the MUT tool similar to Nissan Consult and the Toyota Techstream, etc for all the OEMs.One big problem with the Leaf (and I would guess all purely EV's) is they don't have to comply with the OBD2 protocol
Like the early "wild west" days of CC emissions. Every mfg had their own system. OBD2 put a end to that, and good riddance. I was working in the trade, those early days.That is what i've discovered also with the Mitsubishi. They have the MUT tool similar to Nissan Consult and the Toyota Techstream, etc for all the OEMs.
For ICE cars they have to meet the protocol and PIDs of SAE J2534 spec for scan tool access, but the EVs seem to "almost" follow the spec formats, but they don't use the standard PIDs to identify ECUs, data items, OBDII "modes", etc. Why did they not?
i have been looking at captures from a CAN bridge to intercept the traffic and commands being sent by the MUT and the responses of ECUs. These contain PIDs that are not seen over the regular CAN Buss during normal driving and charging, so are never seen by the phone apps or passive scan tools.
The commands and replies partially follow the format described by the SAE spec, so it looks familiar to some extent, but the differences leave you guessing.
That's not true! You can always test the functionally of an ECU once you've re-flashed it, e.g. a mode change.Like the early "wild west" days of CC emissions. Every mfg had their own system. OBD2 put a end to that, and good riddance. I was working in the trade, those early days.
There are all kinds of scanners on the market, and it can be hard to differentiate between them on their listed spec's alone.
Autel is a US name in the business, there are better and not as good, You are unlikely to know what it can and can not do until you try, and you can't know it does it the "right way" unless you have access to how the software engineers at Nissan intended "it" to be done, all others are reverse engineered, and may or may not be correct.
So if leafspy does it, and it function it must be correct but if Autel does it, it may be suspect? Explain that?Can the Autel properly re-flash Leaf ECUs to change their functionality like LeafSpy does?
It is a multi national with a US presents, I admit I don't know where it was founded, but have been in the business of autoscanners/ repair since 2002. Well known in the "trade" not necessarily the best but not a fly by night company either.By the way, Autel is a Chinese company.
You didn't look in the right placePlease use the Autel on a Leaf and tell us what it does.
Unless you have better info, the Autel website indicates no Leaf????View attachment 3558
Great! Use it and write a review. I've been using LeafSpy since shortly after its release on both my '13 & '19 Leafs. Works great for my needs.You didn't look in the right place
In the over tens years owning a Leaf, I've never had a need to "reset the brake booster zero setting", nor have I had brake booster fault codes.I wouldn't either for one car and one model, as I said before. But if I was still in the trade, and had to deal in many makes and models, I would be looking for one tool.
BTW can Leadspy reset the brake booster zero setting? The 906 Autel can.
Please provide a link. What are the "many quality choices". ThanksHe has a 906, and you can find the spec sheet on their website.
You may not have had to replace a brake booster but that doesn't mean that someone else might. You seam to be arguing that Leafspy is the best/only tool for the job. It isn't, not a bad tool, handy and cheap for the owner, but not the only or best tool out there. Someone who already has a 906 (depending the exact model) will likely find it can do more than Leafspy.
Many of the more difficult problems that can happen on the Leaf, Nissan Consult would be very handy, but not for the car owner, unless they have unlimited funds, likely not worth the cost. There are many quality choices between Leafspy on the low end and Nissan Consult on the high.
