Supported Vehicles
Autokent Techstream supports Toyota vehicles from 1996 to 2022. For newer models (2023+), the clone chips often struggle with encrypted protocols (CAN FD). Older models (Late 1990s to 2015) work flawlessly.
Supported Makes:
- Toyota (All models: Camry, Corolla, RAV4, Tacoma, Tundra, Highlander)
- Lexus (All models: RX, ES, IS, LS, NX)
- Scion (All models: tC, xB, FR-S, iQ)
Typical software setup (Windows)
- Ensure Windows 10/11 (32/64‑bit) PC available.
- Install the correct USB driver for the dongle:
- FTDI-based → FTDI VCP driver
- CP210x → Silicon Labs CP210x driver
- Install Techstream software compatible with the dongle (many users run Techstream versions 9.x–12.x). Use 32‑bit Java requirements only if specified by your installer.
- Connect dongle to PC, then to vehicle OBD-II port (usually under dash).
- In Techstream: set communication interface to the AutoKent/USB interface, choose correct COM port in Device Manager.
- Start vehicle ignition to ON (engine off) or follow Techstream prompts.
1. Bi-Directional Controls (Active Tests)
Unlike basic OBD2 scanners, Techstream allows you to command systems. You can open sunroofs, cycle ABS pumps, test fuel injectors, or engage the A/C compressor directly from your laptop.
