model3dbc's Issues

Front / RearMotorCurrent

Hi,

RearMotorCurrent126
FrontMotorCurrent1A5

are there any update on factor / offset / (un)signed ?

best,

Overlapping config in ID219VCSEC_TPMSData.

I'm getting errors with the latest DBC using cantools in Python:

cantools.database.errors.Error: The signals VCSEC_TPMSDataIndex and VCSEC_TPMSDataIndex are overlapping in message ID219VCSEC_TPMSData.

Appears to be from

model3dbc/Model3CAN.dbc

Line 261 in bb77ae6

SG_ VCSEC_TPMSDataIndex M : 0|2@1+ (1,0) [0|3] "" Receiver

How was this created? There are over 3700 signals

Hi,

First of all thank you for providing this extremely valuable resource, this is hours of fun once I receive my diagnostic cables!!!

Sorry if this is off topic or not the best place to ask, but after going through the whole list, I am surprised at how many messages and signals are present - surely this would be a gargantuan effort to reverse engineer and create over 3,500 definitions manually.

What kind of a process was used to create this kind of file, if it is possible to share any insight? Was there a particular source for each of the parameter names/were these extracted semi-automatically from a rooted MCU?

Thanks!!!

Found some IDs

I'm not pull requesting because I'm not sure if it'll even work... so i found a dbc file online and it has an ID for steering control. Well I was wondering if that ID would still work

(The ID was 0x488 in hexadecimal, 1160 in decimal and the name was DAS_steeringControl). Thanks for the help by the way! 😉

Edit: Or maybe there is some other way to control the steering wheel?

Unknown IDs TM3 Battery Pack 2021

ADAS relevant signals are not found

Hi!

Thanks a lot for the efforts and making this public.

We are trying to get some ADAS info, specifically the following signals:

DAS_ACC_report

GPSLatitude04F

GPSLongitude04F

DAS_objectId

DAS_leadVeh2Dx

DAS_leadVeh2Dy

DAS_leadVeh2Id

DAS_leadVeh2RelevantForControl

DAS_leadVeh2Type

DAS_leadVeh2VxRel

DAS_leadVehDx

DAS_leadVehDy

DAS_leadVehId

DAS_leadVehType

DAS_leadVehVxRel

DAS_leadVehRelevantForControl

DAS_autopilotState

UI_accFollowDistanceSetting

DI_vehicleSpeed

Although we could get some signals regarding the current etc, the ADAS ones where not there.
BTW, we are doing this in Europe. Is it possible that the dbc files are a different here?

Thanks a lot!

What signal is for lock state of the car

I've been looking all over and can't find the signal for whether the car is locked or not... I specifically recall seeing a lock state for the separate doors but I might be mistaken... could someone help?

Thx in advance 😉!

ID5D5RearDItemps issue

When using the current version of the DBC file with can-tools https://cantools.readthedocs.io/en/latest/ , there is an error parsing the file

cantools(cantools.database.errors.Error: The signal DI_lashAngle does not fit in message ID5D5RearDItemps. )

I am not fluent enough in DBC to understand whether this a problem in the DBC file or the can-tools library. It seems commit c61be33 is was caused the change

What is ID for lock all doors?

Hello, I'am looking ID for lock all doors? It is?

Decoding Errors for several messages

I'm trying to decode every message from the CAN bus but I'm getting decoding errors for the following ID's:

• 586
• 609
• 612
• 897
• 921
• 2047

My Model 3 was on the latest 2021 firmware for this dump I'm using. Maybe someone can check what has changed. Unfortunately I don't have the experience to do that myself.

Tesla Model 3 Battery Charger Limit to 333VDC?

Hello, I thought I would send you a message based on your knowledge.

Recently my Tesla Model 3 Battery has been limited to 333VDC. I am trying to understand why this limit has started. I was able to charge this battery just last month to 350-370 VDC

0x22A ID22A HVP_pcsControl
HVP_dcLinkVoltageFiltered: 333V

0x132 ID132 HV BattAmpVolt

Is @joshwardell still active on this? I have a couple of pull requests and seeing no activity with the existing ones

The ID 0x273 for child door lock ?

Hello, I'm looking for child door lock，but it is not find data in ID 0x273. What id is for it? Thanks.

Msg ID 0x7aa (1962) - Enum value 7 - new enum

MsgID: 0x7aa,
Value: 0x07d6ffd6ffbcff00

Cantools error:
expected multiplexer id 0, 1, 2, 3, 4, 5 or 6, but got 7

HVP_debugMessageMultiplexer has a 7th enum value?

Do we just add in "Mux7" as a value to the enum?

Msg 1885 - values that don't decode

Using python cantools:
MsgID: 0x75d (1885)
Value: 0x0effffffff000000
and
Value: 0x0d00000000000000

Error: expected multiplexer id 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 or 12, but got 13 (or 14 for the first value)

Either: the CP_sensorDataSelect has 14 values, or the extra bits after the first 12 options are being used for something else.
