Tesla Charge Port Latch Mechanism Diagnostics

To confirm a fault with the charge port locking mechanism, observe the charge port light ring when the connector is inserted. If the light flashes red and the touchscreen displays error code CP_a054 or CP_a043, the vehicle's internal latch pin is failing to engage. Inspect the mechanical pin inside the port for visible wear, damage, or resistance to movement during the locking sequence.
