2024 Tesla Cybertruck Windshield Camera Fan Noise TSB

Tesla has released Service Bulletin SB-24-10-006 to address a potential issue with the windshield camera fan in certain 2024 Cybertruck vehicles. This bulletin provides detailed instructions for technicians to diagnose and resolve a Cybertruck camera fan noise concern.

Symptoms

Owners of 2024 Tesla Cybertruck vehicles may notice a "buzzing or rattling noise" coming from the windshield camera fan. This noise is typically caused by the fan's mounting bracket not meeting Tesla specifications.

Diagnosis

Upon a customer complaint of Cybertruck camera fan noise, technicians are instructed to perform a diagnostic procedure. This involves running a "Camera Fan Test" routine using a laptop connected to the vehicle via Toolbox 3. During this 60-second test, the technician monitors the windshield camera fan for any noises exceeding normal operating levels.

Repair Procedure Summary

Tesla Service Bulletin SB-24-10-006 outlines a multi-step repair process for the Cybertruck camera fan noise issue:

1. Software Version Check: Before any physical repair, technicians must verify the vehicle's software version. Using the touchscreen, navigate to "Controls (vehicle icon) > Software". If the software version is earlier than 2024.14, it must be updated to version 2024.14 or later. This update is performed using Service Manual procedure 00020003.
2. Fan Removal: The windshield camera fan is then removed from the vehicle, following Service Manual procedure 1722037032.
3. Shim Installation: Three camera fan shims (part number 1893751-00-A) are positioned with their adhesive side onto the windshield camera fan. This step is visually guided by Figure 1 in the bulletin.
4. Fan Reinstallation: The camera fan is then positioned back into the vehicle, and its three screws are installed. The electrical harness on the rear view mirror beauty cover is routed and clipped, and the three electrical harnesses are connected. This process also refers to Service Manual procedure 1722037032.
5. Calibration and Test: A laptop with Toolbox 3 is connected to the vehicle. Technicians must run the "DAS Enter Calibration Mode" routine (Path: PROC_DAS_X_ENTER-CALIBRATION-MODE) and then the "Camera Fan Test" routine (Path: PING-HTTP_DAS_X_CAMERA-FAN-SCRIPT). During the fan test, the "fan_on_duration" is set to 60 seconds.
6. Post-Test Evaluation:
   • If excessive fan noise is still observed: The old fan is removed and discarded. A new windshield camera fan (part number 1811670-00-D), along with new shims, is installed. The "Camera Fan Test" is run again to confirm proper operation. The laptop is disconnected, all removed parts are reinstalled, and correction code S032410006 is used.
   • If excessive fan noise is NOT observed: The laptop is disconnected, all removed parts are reinstalled (referencing Service Manual procedure 1722037032), and correction code S022410006 is used.
