Running Tesla Model 3's computer on my desk using parts from crashed cars

4 hours ago

Tesla runs a bug bounty program for security vulnerabilities in their vehicles.
The Tesla car computer consists of the MCU (Media Control Unit) and the autopilot computer (AP).
Researchers can purchase Tesla Model 3 parts, like the MCU and touchscreen, from salvaged cars on eBay.
To boot the car computer, a 12V DC power supply, touchscreen module, and display cable are needed.
Tesla publishes wiring schematics publicly, including details on connectors and pin functions.
The display uses a 6-pin Rosenberger cable, which is hard to find individually.
An improvised setup with a BMW LVDS cable failed, damaging the MCU.
A replacement MCU was repaired after identifying and replacing a burned power controller chip.
The only solution was to purchase an entire dashboard wiring harness to get the correct cable.
With the correct harness, the car computer booted successfully, allowing interaction with the OS and network interfaces.
