How can you tell the difference between OBD1 and OBD2?.Can I use a USB to HDMI cable to connect my laptop to my TV?.Make everything neat with heat-shrink tubing. Cut off the other side of it, and connect to your $7.66 USB to ALDL adapter. But this proves that an ALDL-interface cable can be built for $7.66 including shipping.Įxtra credit: For an additional $5, order. Step #10: Start engine to get some more meaningful data, but you should be getting data flow just from being in "RUN" and trying the "Force Data" function.ĭisclaimer: This worked on my 1992 LH0-engined car. Press "Force Data" button in Freescan screen if data does not transmit automatically. You should get at least a partial data flow when the key is in the RUN position.

If not, then you've done something wrong earlier.Īlternatively, use a terminal emulator such as PuTTY, set into serial mode, with the appropriate (virtual) com port (mine was COM4), and the baud rate set to 8192.

Wire the combined TXD and RXD pins to the "M" connector on the ALDL block Wire the TXD and RXD pins together, Green and Yellow. Many Arduino-targeted cables use 3.3V, which may not be adequate for the TX pin to the 5V logic used in the ECU!) (must be this one, with the FTDI chip to support 8192 baud, and must use 5V TTL levels. Okay everyone, as a public service, I thought I'd do a bit of a write-up on how hooked up to my 1992 LH0-engined car with a <$8 USB cable and no messing around with MAX232's, transistors, resistors, or even soldering.
