Important Fitment Note
Please verify that your original part number is 1143746-01-D before ordering.
This product is designed for the front windscreen triple camera position, located in the upper windshield area above the rearview mirror.
It is not intended to replace other camera assemblies with similar appearance but different functions or part numbers.
Installation Instructions
Installation Position
This camera assembly is mounted in the upper front windshield area, directly above the interior rearview mirror.
Tools Required
-
Plastic pry tool set (to avoid scratching interior and camera)
-
T10 Torx screwdriver/bit
-
Torque wrench (0–5 Nm range)
-
Microfiber cloth & glass cleaner
-
New T10 one-time screws (6 pcs, replace old ones)
-
Tesla diagnostic tool (for calibration, mandatory)
Installation Steps
-
Turn off the vehicle and disconnect the 12V battery negative terminal for safety.
-
Gently pry off the four-camera upper cover (above the rearview mirror) with a plastic tool. Disconnect the passenger camera wiring before fully removing the cover.
-
Remove the camera hood by taking out 2 one-time patch screws, then expose the triple camera assembly.
-
Loosen the 6 T10 one-time screws (diagonal order) to remove the base plate, then disconnect the camera connector (rotate the connector to the side for easier operation).
-
Carefully take out the old camera, do not touch the lens. Clean the mounting bracket and windshield view area with glass cleaner and microfiber cloth.
-
Align the new camera with the positioning pins on the bracket, reconnect the connector firmly, and cover the base plate.
-
Install new T10 screws and tighten them to 1 Nm torque (diagonal order to avoid base plate deformation).
-
Reinstall the camera hood, upper cover and rearview mirror, then reconnect the 12V battery.
-
Mandatory calibration: Use Tesla Toolbox 3 or a professional diagnostic tool to clear old calibration data and recalibrate the camera. Without calibration, Autopilot/FSDB will fail.
Important Warnings
-
✅ Never touch the camera lens — fingerprints or oil stains will cause Autopilot misjudgment.
-
✅ Use new one-time T10 screws only — old screws cannot be reused (risk of loosening).
-
✅ Calibration is mandatory after installation — no calibration = loss of Autopilot/FSDB function.
-
✅ Use only plastic tools to avoid scratching the interior, camera or windshield.
-
✅ If the mounting bracket is detached from the windshield, re-bond it with polyurethane glue and let it cure before installation.
-
✅ Professional installation is recommended. For non-professionals, please consult a certified Tesla technician.
Note: This camera is a safety-critical component. Improper installation may affect driving safety. Please follow the instructions strictly.
