  • 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.
