Troubleshooting by symptom
Narrow down the symptom and current version before changing settings.
Access and settings
| Question | First step |
|---|---|
| Fleet will not open | Use http://DEVICE-IP:7000; check the network and IP |
| Where is the CarrotMan APK? | CarrotMan / CarrotLink integration is currently unsupported; use Carrot Web |
| Settings stayed the same after an update | Persistent values may be retained; catalogue defaults are not necessarily current values |
| My defaults differ from someone else's | Distinguish catalogue defaults, initial Params values, saved values and vehicle |
| Some settings are missing after restore | Review excluded/invalid items; DM Enabled is not transferable |
Driving and inputs
| Symptom | Check |
|---|---|
| One press changes speed a lot | CruiseButtonMode, CruiseSpeedUnitBasic, CruiseSpeedUnit |
| Long-press increments differ from my setting | Current acceleration/deceleration long presses use an internal 10 km/h grid |
| Speed keeps being reduced below my target | A lower lead, curve, camera or route target may be active |
| Same gap level feels different | TF, speed multiplier, driving mode and lead response |
| Lane change starts too early | LaneChangeNeedTorque, LaneChangeDelay and turn-signal request conditions |
| Radar points appear without braking | Display points and control lead objects are different |
| HKG Kp/Ki settings are hidden | Current common controller fixes Kp at 1.0 and Ki at 0 |
| Control will not enable after an impact notice | Possible automatic Dashcam transition; park and check the openpilot toggle and restart |
Disengage and collect evidence for CAN, steering or braking errors and unexpected behavior; do not mask them through tuning.
Problems after an update
- Record branch and commit in Tools → Info.
- Separate newly changed settings from pre-update values.
- Check the detected vehicle against the actual vehicle and harness.
- Prepare screen recordings and logs before and after the event.
- Before switching commits or resetting, preserve local code changes and settings.
git sync, git reset and reset repo are not simple refresh operations. Local changes may be lost.
A useful support request
Vehicle·year·configuration / device / branch·commit / event time / actual symptom / driver intervention / recently changed settings / log link
Example: “Around 14:32 at 80 km/h, strong deceleration as a vehicle approached from the right merge. Disengaged with brake. First occurrence after update. Uploaded three segments around the event.”
