🕝 BMW iX3

[Clarkyncl]

Hi Jeff,

Finally got my OBD scanner in, and checked the repository for the iX3 and it’s currently empty. What do I need to do next? It can’t even read the VIN at the moment.

I could try with the x3 40i parameters? They in theory should mostly be the same?

Cheers!

Not reading the VIN means there's some onboarding work to do. Can you send me an export of your OBD scan sessions? I'll take a look at the VIN requests to see if there's any hints there: https://sidecar.clutch.engineering/help ... -scan-logs

In a Terminal session, let's try running the following to see if we can get some of your car's data:

Code: Select all

22E5CE

If that doesn't return a bunch of data, let's try talking to the specific ECU:

Code: Select all

ATSH6F1
22E5CE

And if that doesn't work, we might need to enable manual flow-control:

Code: Select all

ATSH6F1
ATFCSH6F1
ATCRA607
ATFCSD07300000
22E5CE

Once you've ran the above commands, send me your OBD scan logs and I'll look into wiring this up.

And another command we can try testing in a new terminal session:

Code: Select all

22F150

And also this command in another new terminal session:

Code: Select all

1A80

I'm pre-emptively adding SOC and SOH for the iX3 in https://github.com/ElectricSidecar/BMW-iX3/pull/2. If you register your car as an offline vehicle in Sidecar and then set it to the fallback override for your scanner, you should be able to pull these parameters even though the scanner isn't finding your VIN yet.

[jeff]

Merged in SHA: cf18811. https://sidecar.clutch.engineering/help ... parameters for confirming your vehicle parameters version.

[jeff]

Which scanning hardware are you using btw?

Looks like none of the commands succeeded in talking to your car, so we'll need to try a different strategy. We'll first try to see if we can get the scanner to auto-detect the protocol your car is using:

Code: Select all

ATZ
ATSP0
ATDP

You might need to then run ATDP again a couple times until it settles on a protocol.

Once you've ran the above, please share the resulting protocol here.

Morning! I’m using the icar pro 2s - I get the following:

Also, when I have it open on CarPlay, it centres on my car then scrolls east/west for 2 seconds then re-centres on the car again - only when I’m on the move though.

[jeff]

Ahh I missed one command in the startup sequence, my apologies.

Can you try pasting this full block into a Terminal session and sharing the OBD logs with me once you've done so:

Code: Select all

ATSH6F1
ATFCSH6F1
ATCRA607
ATFCSD07300000
ATFCSM1
22E5CE

I was missing the ATFCSM1 command which is critical for enabling manual flow control.

Are you still seeing this issue with v1.18?

[Clarkyncl]

Hi Jeff, just upgraded last night and yes, it scrolls whilst moving. I’ll try and get a video of it if I can and email it over
