My truck started running rough, so I dug out my OBD code scanner and
found that it had died.

So I rummage around the internet and found I can get a OBD to usb
converter or a OBD to blue tooth device. Anyone have opinions on
this.

Any sites with info on making a OBD code scanner. I already have a
case and a OBD connector.

I have the USB converter cable & it has worked fine on every car or
truck I have used it on.

The blue tooth would be better only if you plan on gathering data while
you are driving the vehicle, IMO.

Unless you're talking about putting the laptop in the back seat, a simple
cable clamp will fix that. I mounted one under the dash, right about over
the hump, in order to keep the OBDII reader cable from getting tangled in
my feet.

If you have a laptop the USB connector is the way to go. There is plenty
of free software.
You should be able to get what you need for under $20 on ebay

You can buy the whole thing on Ebay for $8.


http://hem.passagen.se/tomasf/obd2/OBD2.pdf is a schematic for a ISO
9141-2 to R-232 converter that will work on Chrysler and some other
brands, but GM & Ford use a different interface. The OBD-II connector
currently supports three or four different 'Standard Interfaces'.

You can buy an IC called the ELM327 which is a preprogrammed PIC
processor to make a general purpose interface. The STN1110 is Another
OBD-II interface IC. Either of thesse require you to write some code.

Or if your project is to get the truck running and not to build an OBD
scanner, haul it down to one of the chain parts places and they'll
read the code(s) for free. Interpretation is left up to you.

Good advice. I got the truck running, but still want to have a
working obd.

Here is a project using a readily avaible Ardino board. You can buy
the board on Ebay for $20

Harbor Freight has had the 98568 OBDII scanner on sale for as low as $40.
It's an Autel MS309. I bought one to ensure that I'll never need it. It
seems OK though there were no fault codes to read.

I have one from HF, too, but the OP wanted to know how to build his
own. I also pointed out a USB to OBD-II adapter is available on Ebay
for $8.

My HF OBD-II reader just told me that I have a defective 'Over
pressure Sensor' inside my automatic transmission, and some online
research shows the sensor costs $85, and the labor will be $$160 or
higher. Unless it's the PCM giving a false reading, which will be
around $500.

I just bought this on Ebay for $7.86, including shipping. It is a
OBD-II to USB version, with software, and has more functions than the
cheap handheld units. Plug it into an old laptop and you're ready to go.


Item: 220838688671

I have the Harbor Freight model that's on sale. It will display
codes, but not clear them after a repair.

Thanks. I printed out the ebay info. The OBD that I have is a
Harbor Freight model. It would clear codes when it was working. But
it sounds as if things have improved and this one ought to work well.

Just make sure it matches the description for that item. Some of the
interfaces are for European markets only, and don't use the same
protocols as vehicles made for the US market.

You might want to open the HF unit and see if it's just a broken
wire, or bad solder joint. Mouser sells the OBD-II connectors and pins,
if that's all that's bad. They also sell them for the vehicle's data
port.
