Summary
Stock comma 4 / openpilot 0.11.1 on release-mici failed to recognize a supported 2023 Hyundai Tucson Limited with the Hyundai N harness until an already-present commaai/opendbc master firmware line was added locally.
Environment
- Device: comma 4
- Installed openpilot:
0.11.1
- Branch:
release-mici
- Commit:
70e157462304e5ce7d03ffbec6cb7f45bf347bb7
- Vehicle: 2023 Hyundai Tucson Limited, US
- Harness: Hyundai N
Symptom
Device showed dashcam mode / unrecognized car.
Logs before local patch showed:
car_fingerprint: None
car doesn't match any fingerprints
fw_count: 12
canValid: true
The device was able to read vehicle firmware and VIN, so this did not look like a dead harness/CAN path.
Relevant firmware
Observed forward camera firmware:
NX4 FR_CMR AT USA LHD 1.00 1.00 99211-CW010 14X
Observed radar firmware:
NX4__ 1.01 1.00 99110-N9100
On the installed release, 99211-CW010 14X was present under HYUNDAI_SANTA_CRUZ_1ST_GEN, but missing under HYUNDAI_TUCSON_4TH_GEN.
Current commaai/opendbc master already includes this line under HYUNDAI_TUCSON_4TH_GEN:
b'\xf1\x00NX4 FR_CMR AT USA LHD 1.00 1.00 99211-CW010 14X',
Local verification
Adding that one firmware line locally under HYUNDAI_TUCSON_4TH_GEN, clearing cached car params, and rebooting caused the car to fingerprint successfully:
car_fingerprint: HYUNDAI_TUCSON_4TH_GEN
source: 1
fuzzy: false
cached: false
canValid: true
Request
Please make sure the comma 4 stock/release path picks up the current opendbc Tucson firmware table so supported 2023 Tucson vehicles with this camera firmware are recognized without a local patch.
