Recently, I made datalogger cable to connect Toyota ECU with DLC1 or DLC2 to computer via serial port.

Scheme:
ECU –> DLC1 –> Serial Port –> USB to Serial Cable –> Computer –> Datalogger Software

What is DLC1?
DLC1 (Data Link Connector 1) is the type of terminal which is used in early Toyota Car. DLC1 Year range: 1990-2000. DLC2 Year Range: 1988-1996.

Hello.
Thanks for you article.

Could you maybe tell me, exactly how did you connect the RS232 to the DLC1? Could you make a pin-for-pin diagram?

Regards,
Casper
