Wrote a quick python script to match up these ID's with the spreadsheet. This is what I found:

73d - BSM
74d - IPDM E/R
744 - HVAC
755 - PARKING BRAKE
7d4 - BSM
7b7- SONAR?```

[robin-reckmann]

@avolmensky This fits to my list also. 7B7 is listed as AVM (around view monitor).

Furthermore I have this ECUs: 740 - ESP / ABS (its actually the abs ecu handling nissans vdc)

[robin-reckmann]

For fpv2, I would go with the following ECUs for the leaf:

0x707 - Ecu.fwdCamera 0x740 - Ecu.esp 0x742 - Ecu.eps 0x79d - Ecu.transmission

And with these for the X-Trail:

0x740 - Ecu.esp 0x742 - Ecu.eps 0x743 - Ecu.combinationMeter 0x7e0 - Ecu.engine

And it seems that all of these have a 0x20 offset, so we dont have to blow up the fw_query script with the 5 different nissan offsets :-)

If all Nissans have IPDM E/R, bsm, hvac or parking brake, we could add them to the car.capnp later on.
