Using clone ELM327 Bluetooth OBDII adapter with Leaf

[palmermd]

Actually I need a sample of an active DTC. That is one that just came on. Perhaps you could plug drive then unplug to get the error light to come on and then see if the second set of bytes after the DTC have different values.

after re-triggering the dtc. Still no error lights or any visible sign to the driver. Added one to the error count.

Actually two of them with to "9" from "8" so I think that means a current DTC instead of a past one. I don't think it is a counter. But try it again and see if it increments.

You are correct. When I enabled the heater again, they both went back to 8, and then after disabling again they went back to 9.

With v26n3:

one car has a B2820

and another has:
B2820 0028 CHARGER
P100B 5703 EV/HEV
P31C2 C0D0 EV/HEV
P2100 C031 EV/HEV
B38C0 0000 EV/HEV

Thanks Gary. Those are not real DTCs for the EV/HEV just the raw data so I can see how to decode it. I will look it over and come up with a version that displays the real DTCs.

Gary,
I just notice you were using 26n3. That version had a bug in dumping the raw data for the EV/HEV DTCs. Can you install version 0.26n5. After you get the DTCs tap on the DTC panel to go into Zoom mode to be sure you see all the EV/HEV data. The list format in your post is just what I need.

Not all, even seemingly identical, ELM devices work well.

Also, there is no Bluetooth on some Android devices, and
some devices (and OS levels), work better and others do not.

So, the simple"any Android", and "any ELM327 type device"
is somewhat misleading.

That's still about all the information you need. It's more of a blacklist concept (some exceptional devices are *not* compatible), not a whitelist. There aren't so much "known good adapters" and "good devices" as there are exceptional cases of not working properly. Very rare to find an Android device - most people having Android phones that I know - that doesn't also have Bluetooth... and the first OBDII adapter I bought off Amazon worked without a hitch (it would be returned if it doesn't work properly, because non-working ones would be defective).

Just saying it could be simplified a bit.

Version 0.26n6 is up for testing.

This version is the same as 0.26n5 except it uses a different request to get DTCs from the EV/HEV ECU.

Gary and anyone else who have Leafs that have EV/HEV DTCs please run this version and list what hex data gets displayed for each EV/HEV line.

It is possible that you won't get any EV/HEV DTCs listed where as you did for version 0.26n5. If that happens then this is not the request I should be using.

The DTCs that I decode from Gary's data are U02C0 and U0031 however neither of these is listed so I may be looking at the wrong response data which is why I am trying a different request to see if that works any better for the EV/HEV ECU.

Does anyone know of an easy way I can force a DTC in the EV/HEV unit on my Leaf? That would make it much much easier for me to work out the correct sequence to read it out.

What about unplugging the dc cable from the charger. Should allow the charger to boot and then throw a code when no current passes to the battery, or no DC voltage detected at the charger after the relay closes.

I don't recommend this sloppy installation, but the pictures are handy.

Need a higher resolution picture.

I've updated my original post with a higher-resolution picture.

For future reference, when the picture is hosted at google like that, you can just tweak the URL to get whatever resolution you want.
For example, change:
~https://lh5.googleusercontent.com/-K_mPzvhGLrA/UhHjYMEDCYI/AAAAAAAAGDc/PHVK3-eVpYA/s300-k/photo.jpg
to:
~https://lh5.googleusercontent.com/-K_mPzvhGLrA/UhHjYMEDCYI/AAAAAAAAGDc/PHVK3-eVpYA/s600-k/photo.jpg
To go from an image that fits within 300 pixels square to one that fits within 600 pixels square.
You can even choose width & height separately:
~https://lh5.googleusercontent.com/-K_mPzvhGLrA/UhHjYMEDCYI/AAAAAAAAGDc/PHVK3-eVpYA/w720-h1000-k/photo.jpg
This fits the image into a 720x1000 box. The image itself keeps its original ratio, so in this case the actual image size is 600x1000

Also can you send me an ELM Trace as you have many EV/HEV DTCs.

I actually grabbed that screenshot right before leaving for a business trip. I'll try to remember to do so when I get back.

Feature request:

Would anyone else find pack voltage useful on the 4th screen? That along with power in/out of the pack in kW would be useful, especially if those values are updated frequently while on that screen and individual CP voltages are not. Those are the only two things I found useful in my GID meter that aren't present n the LEAF Battery App.

Does anyone use the 3rd screen? I find that I typically only use screen 4 while driving and then screen 1 if I want Ah or CP readings.

I agree. Voltage and Current meters have been a requirement in all conversion EV's and I'm not sure why the factory EV's have opted not to display this information. But Voltage and Power meter would be just fine...probably better.

Hi all,

Does anyone know of an OBD2 scanner that shuts off by default when the car is not on/running? I've read some people in this thread mention the switched unit from Amazon ( http://www.amazon.com/gp/product/B00BL3KQZO/?tag=myelecarfor-20&/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1#productDetails" onclick="window.open(this.href);return false; ), but the switch only seems to turn the Bluetooth off according to reviews.

I've also read on the Leaf Battery Application wiki ( http://www.mynissanleaf.com/wiki/index.php?title=Leaf_Battery_Application" onclick="window.open(this.href);return false; ) that the Vgate ELM327 ( http://www.amazon.com/Vgate-ELM327-Bluetooth-Scanner-ANDROID/dp/B00AAOOQJC/?tag=myelecarfor-20&/ref=pd_sim_sbs_e_6" onclick="window.open(this.href);return false; ) can be modified to turn off with the car if you swap wires on pins 8 and 16. I'm a little hesitant to do that without a more clear understanding of what these pins do - does anyone know? Has anyone here used this trick to basically leave the OBD2 scanner plugged in all the time and not draw any current when the car is off? Is there any harm in doing so and always logging data through the OBD2 port?

Thanks a lot, and this is an amazing application! I can't wait to get it going on my Leaf!

I've done this mode for a couple of people and it is very easy to do and works fine. All it is doing is moving the power feed for the entire OBDII module from the always on pin to the only on when car is powered pin.

Ah, great, thanks!

Any worries with leaving it plugged in with the Leaf Battery Application running at all times?

[TomT]

Only if you are worried about power consumption. It pulls about 2 watts (200 mills) when on... Over a week or two with the car off, it could add up...

v0.26.n6, 2011 Leaf

I don't have any DTCs showing using n5 or n6. Had a DTC that was checked by a Dealer prior to doing the software upgrade recently. Guess everything was cleaned up by that? Have not tried setting tires yet. Everything else looks good.

I too like the ability to see Amps, Battery Voltage and Power.

Fabulous app. Allowed me to use the car's range to the max to make 6 long trips efficiently this past weekend.

 

[BoulderLeaf]

Even with the pin mod, so it is only "on" when the car is? Or, is that the consumption prior to the mod?

Thanks! It's ordered and when I get some free time I'll break out the soldering iron.

Before I modified to switched power, I accidentally left the App running with screen 'always on', and it drained my 12V down to 8V overnight. It's an easy mod if u buy the 'stubby'.
