Sending CAN Buss comands

[gwguidi]

Will the controller board for a Tesla motor be able to send commands to my power steering pump on my Mini Cooper?

Required messages are:
CAS (key switch)- 0x130 - Terminal status
DSC - 0x1A0 - Vehicle speed - Impact on assistance
Engine ECU - 0x1D0 - Engine Run

Not realy as these will need a crc and static frame info. Not what the OI CAN mapping is setup to do.

I need help reading transmitted data from my Tesla Small drive unit.

I have set up the Open Inverter board to transmit messages, but I can not receive anything, even with a CAN interface connected to SavvyCAN.

I have CAN speed at 500k 100ms with default IDs. I have checked the CAN connections and confirmed that they are properly terminated (measure 60 ohms between the CAN L and CAN H when only the DU and CAN interface are connected to each other.

I wil appreciate any help I can get to solve this as it is blocking me from completying the project.

Post more info. Params + pictures.

What devices are on the bus? I anything acknowledging the CAN being sent?

Here are my CAN parameters

These are the CAN messages I have mapped for transmission:

For testing, I only have the Landrover Freelander CANBus running at 500K, which includes just the Instrument cluster, SRS and ABS modules. I also have an Arduino imitating the gearbox selector, which is adding gear selected position CAN messages needed by the ABS and instrument cluster.

I am using an ESP32 with SN65HVD230 CAN transceiver running SavvyCAN. This setup can read messages from the landrover module but can't receive any messages from the Drive unit.

I have added my current parameters file as well for your review.

Any other photos you need?

Sorry, forgot to add the CAN connection drawing. The Instrument cluster and OpenInverter board are on both ends of the bus, each with the 120ohm resistor.

Just use the zombieverter and select the BMW E65 under vehicles, then you'll have peace and quiet. The CAN IDs are the same as for the Mini. Furthermore, the zombie can also perform many other tasks, such as controlling pumps and fans.

Let me give this a try and revert.
