The scan showed a system-wide problem
U0104 communication faults, a U3006-16 low-voltage history, P2583-87 lost communication with the millimeter-wave radar, and U3000-49 internal electronic failure pointed beyond a lost aiming value.

Honda Pilot LKAS camera fault: why U3000-49 stopped calibration.
A 2020 Honda Pilot arrived with driver-assistance warnings and a camera that appeared physically intact. The scan data—and what happened after the first checks—showed why this was not a simple calibration job.
Real AutoLab diagnostic case. Customer, registration, VIN, claim, and identifying details have been removed. Vehicle-specific results vary.
What the vehicle showed
The warning was the beginning—not the diagnosis.
ADAS warnings often involve several systems at once. The useful question is not simply whether a calibration can be selected, but whether the vehicle is electrically, mechanically, and electronically ready to complete it.
- 01
Lane-keeping and related driver-support systems were unavailable.
- 02
The scan contained 20 total DTCs, including 14 within the Integrated Driver Support System.
- 03
The windshield-mounted multipurpose camera felt unusually hot.
- 04
The camera and front radar were connected and showed no obvious external damage.
Diagnostic path
What changed the direction of the job.
These are the observations and decisions that separated a calibration attempt from the actual next step.
Physical appearance did not clear the camera
The camera was plugged in and visually intact, and the radar remained installed. That did not outweigh the internal-failure code, heat concern, and network history.
Calibration could not begin with active faults
The calibration routine was not the repair for an internal or communication failure. The vehicle first needed the active electronic condition resolved and stable module communication restored.
Replacement alone did not close the diagnosis
When the same code returned after the initial replacement path, the job still required power, ground, network, configuration, and related-system diagnosis rather than repeated calibration attempts.
What this case teaches
Calibration only works when the prerequisites are right.
- 01
A camera can be connected and visually undamaged while still reporting an internal electronic failure.
- 02
Heat is a clue only when it agrees with the warning behavior, communication status, and trouble codes.
- 03
Low-voltage and network faults must be evaluated because one ADAS module can create warnings across several systems.
- 04
A calibration routine cannot compensate for an active internal, power, wiring, or communication problem.
Start with the vehicle
Have a Honda Sensing or LKAS warning that will not clear?
Start the assessment with the VIN, dashboard warning, scan report, and whether the windshield or camera was recently replaced. We’ll review whether the vehicle is ready for calibration or needs diagnosis first.
