In this video, we build a custom CAN Bus Sniffer using a Teensy 4.1 and an SN65HVD230 transceiver to "hack" into the Corolla's brain and read the raw data stream.

The Origin Story: I recently got a message from a viewer on LinkedIn asking a tough question: "How do we access high-speed CAN Bus data without buying expensive, proprietary hardware?"

It’s a great question. Most "Dealer Tools" cost thousands. Even hobbyist analyzers can be pricey. So, I decided to build the solution for under $30.

The Mission: We need to find the specific "CAN ID" for the Engine RPM (likely 0x2C4) so we can eventually "spoof" it. This is the only way to keep the Electric Power Steering alive once we rip out the gas engine.

What we cover:

The Challenge: Why proprietary tools lock you out.
The Hardware: Wiring the SN65HVD230 to the Teensy 4.1 (Safely!).
The Code: Using the FlexCAN_T4 library to sniff data.
The Matrix: Decoding the raw Hex data in real-time.
