Front Right-Hand (RH) Door Latch for 2023+ Tesla Model 3 | 1738946-01-D (CFN Brand)

Core Functions

1. Synchronized Locking & Unlocking: Connects to the Body Control Module (BCM) to execute commands from the key fob, touchscreen, or exterior “press-to-unlock” handle. When locked, it engages the stainless steel striker pin (on the door pillar) to prevent accidental opening during driving; when unlocked, it releases smoothly for easy access.
2. Reliable Operation & Status Alerts: Features a high-response solenoid (acts in ≤0.3s) for instant handle-triggered opening, plus a mechanical backup linkage for the interior handle (works if power fails). It has a “half-latch” function—catching the striker if the door isn’t fully closed and sending a “Front Right Door Ajar” alert to the dashboard.
3. Safety Protection: Auto-locks during collisions (via airbag sensor signals) to avoid occupant ejection; includes a hidden manual pull tab for emergency opening (if electrical systems fail). It also coordinates with the door’s anti-pinch sensor, reversing closing if resistance (e.g., a hand) is detected.

Durable Construction

• Mechanical Structure: Main body uses glass-fiber reinforced PA66 plastic (tensile strength ≥85MPa) to resist impact; moving parts (locking pawl, ratchet) are hardened steel (HRC ≥52), supporting 60,000+ opening cycles.
• Electronics: Solenoid with copper coils (insulation class B, withstands 130°C) for stable performance; Hall-effect sensor (accuracy ≤0.8%) provides real-time status feedback to the BCM.
• Environmental Resistance: IP6K7-rated gaskets block water/dust; tolerates -40°C to 90°C, resisting salt corrosion (suitable for coastal areas).

Installation

1. Power off, disconnect the 12V battery; remove the front right inner door panel (detach clips, disconnect window switch/exterior handle wiring).
2. Remove old latch: disconnect its electrical connector and mechanical cables, unscrew 3×10mm bolts, and pull it away.
3. Clean the mounting surface; check the striker pin (tighten bolts if loose, replace if corroded).
4. Align 1738946-01-D, reconnect the connector and cables, hand-tighten bolts, then torque to 8±0.5 Nm.
5. Reconnect the battery, reinstall the panel; test locking/unlocking, anti-pinch, and clear BCM error codes (via Tesla tool).

Note: Front RH-specific—do not interchange with front left (e.g., 1738944-01-D) or rear latches. Non-compatible parts cause malfunctions or safety errors
