🕝 BMW iX3

[jeff]

@Clarkyncl are you still seeing the weird scrolling behavior in v1.19? I still haven't been able to reproduce it yet Let's move discussion of this specific bug over to viewtopic.php?p=928#p928

[jeff]

Looking into this again, a few more things for us to try. I have a suspicion the iX3 needs just a little bit more coaxing, so please run the following in a Sidecar Terminal and share the logs:

Code: Select all

ATSH6F1
ATFCSH6F1
ATCRA607
ATFCSD07300800
ATFCSM1

22E561
22E5C7
22E5CE
22E54D
22DDC0

Explanation of what's going on here

Code: Select all

> ATCEA07

Set the CAN extended address to 07. This causes the ELM327 to insert the 07 as the first data byte of all CAN messages that we send.

Code: Select all

> ATSH6F1
> ATFCSH6F1
> ATCRA607
> ATFCSD07300800
> ATFCSM1

This is a pretty standard filtering sequence and it's what helps us target our commands at specific ECUs in the car.

All of the 22*-prefixed commands are the parameters we want to test.

To get the vin we can maybe try a similar thing as the above. Please run the following in a terminal and then share the logs:

Code: Select all

ATCEA07
0902

[Clarkyncl]

Hmm, no bueno - just getting a lot of no data back - I’ll send the logs over now. Not had a chance to check the scrolling maps yet, I’ll check at lunchtime

[jeff]

Hey @Clarkyncl! I don't see those commands in the OBD logs you sent over; can you give it another try?

In one terminal session, please run:

Code: Select all

ATCEA07
0902

And then in another terminal session, please run:

Code: Select all

ATSH6F1
ATFCSH6F1
ATCRA607
ATFCSD07300800
ATFCSM1

22E561
22E5C7
22E5CE
22E54D
22DDC0

[Clarkyncl]

I’ve just re run the above and I’m getting something back this time! I’ll send logs over!

[Clarkyncl]

I forked up... and got it working! It now shows SoC and SoH

[jeff]

@Clarkyncl Can you send me another export of your OBD logs? I'll see if I can get the remaining parameters wired up.

And before doing so, let's see if the X3 pids work on the iX3:

Wheel speed

Code: Select all

ATSH6F1
ATCRA629
ATCEA29
ATFCSH6F1
ATFCSD29300800
ATFCSM1
22DBE4

Vehicle speed + odometers

Code: Select all

ATSH6F1
ATCRA660
ATCEA60
ATFCSH6F1
ATFCSD60300800
ATFCSM1
22D107
22D10D

[Clarkyncl]

Done! I think I've got the Battery State of Health wrong - it's still giving all different figures from 58% to 100%. Doesn't seem to be any rhyme or reason for it.
