Yeah thats pretty much nothing.
It does however make sense that more data will flow when the ignition is on. Lets see what we get once your PCB is complete.

Right, I figured there's alot of communication btwn the modules and bcm when the ignition is switched on.Originally Posted by DynamoBen
I'll get the pcb completed quickly, I can't wait to see what it produces.
Oh, and now the boxes are there,forget the edit.
Talk to you soon
OK, I've got the elm322 chip, etched and built the pcb and it works !
I'm using hyperterminal and it's displaying all the data on the bus. I'll post the data I'm interested in for programming into the PIC asap.
It appears that it will display the data in ascii or hex.
Thanks for steering me to this setup.
I would never lead someone astray when it comes to OBDII
Post your data so we can get you rolling. I'm as interested as you are.
You need all codes and error code to control with pic, download all codes

precision it seems you didn't read through the entire thread. He is not trying to read OBDII error codes from the ECU, thats easy. He is trying to control devices on the VPW data buss, a little more difficult task; but it is well in hand.
DynamoBen,
should I post the data in hex or ascii or both ?
