D9 — Troubleshooting & Maintenance

Quick Health Check

Run through these in order before deeper debugging:

LEDs — see the LED table in Specifications.
Power — multimeter on B+/GND at the device plug. Expect 9–36 V.
SIM — insert in a phone, verify data works, check PIN is disabled.
SD card — genuine Class 10+, FAT32, < 256 GB.
Traqcam Connect → Platform — confirm main server is d4.traqcare.com : 5101 with protocol 2013.
Traqcare → Settings → Devices — confirm the IMEI / Device ID exactly matches what Traqcam Connect shows.

Problem	Solution
Recording invalid	Use FAT32 and a storage card with read/write speed Class 10 or higher.
Loop recording invalid	Check free space on the SD card. If full, format the card.
Video is blurry	Remove the lens protective film. Clean the lens and the windshield.
No audio in recording	Make sure the recording function is enabled in the app.
Device temperature is too high	Expected — AI runs heavy computation. Do not touch the heat sink while in operation to avoid burns. Ensure airflow is not blocked.
Files cannot be opened on a computer	Try a different video player. If still unreadable, the card may be damaged — reformat or replace it.
Device never comes online on Traqcare	Check 4G LED (should be solid yellow), SIM data plan, platform settings in Traqcam Connect, and that the Device ID in Traqcare matches.
GPS LED never goes solid	Move the vehicle outside with a clear sky view. Verify the external GPS antenna is seated on the 4-pin BMW head.
Wi-Fi cannot connect from phone	Press the device Wi-Fi button again. Default password `12345678`. Forget and rejoin the network on the phone.
Calibration stuck at a percentage	Drive above 20 km/h — calibration pauses at lower speeds.
Other	Restore to factory settings, or contact local technical support.

Keep the device dry. Do not let the device or cables stay in a damp environment. Do not operate with wet hands — short circuits, corrosion, or shock may result.
Avoid strong impacts or vibrations to prevent equipment malfunction.
Do not store in extreme temperatures — outside the operating range can cause malfunctions.
Do not hit, throw, or puncture the unit; avoid drops and squeezing.
Use only officially approved power and data cables.
Do not disassemble the unit or accessories without authorisation — doing so voids the warranty.

Alerts from active-safety AI cannot replace the driver's decisions and operations.
Recognition accuracy varies with road and weather conditions and is not 100 %.
Do not attempt to view stored data or change device settings while driving. Operate the device only when the vehicle is stationary and parked safely.
Do not install the device where it blocks the driver's view or interferes with the steering wheel, pedals, or gear lever.
Do not place the device in front of or on top of any safety airbag.
Some countries or regions prohibit or restrict drivers from playing videos on devices — comply with local law.
