Dataport not scanning?
Saturday, February 17, 2007 10:54 AM
Is this a problem for anyone else? I cant get any reading from my data port. Before using a code scanner I use to be able to play around with it for a second to get it work but now with hp tuners its just not connecting/ Already replaced the cig fuse and its still not working... Any ideas?

check power at pin 16... Also make sure all your grounds are good and tight....

The pins are used in the following way:

Pin 2 - J1850 Bus+
Pin 4 - Chassis Ground
Pin 5 - Signal Ground
Pin 6 - CAN High (J-2284)
Pin 7 - ISO 9141-2 K Line and ISO/ DIS 14230-4
Pin 10 - J1850 Bus
Pin 14 - CAN Low (J-2284)
Pin 15 - ISO 9141-2 L Line and ISO/ DIS 14230-4
Pin 16 - Battery Power

If your connector has extra pins, don’t worry. Manufacturers can use them as they see fit.

Check power at pin 16? Using test light or voltimeter?

I had the car fixed the next day. That was the problem Jason. Since that I've had to have my PCM replaced because it took a crap.
