Hey, just wondering if anyone knows if an OBD1 scan tool can be modified to fit the infamous OBDII style scan port. I don't need the engine scan part
right now so I want to know if I can modify it to pull ABS codes. I have the CP9001 actron scan tool that has a switch to go between "check engine" and "ABS scan".
This is a picture of the conversion I'm trying to make but I want to know what pins I should jump to. I think the OBDI scanner I have uses the F, and L pins. I am thinking I can jump them to the OBDII port with some wire and alligator clips. Has anyone tried this? Does anyone know what ports I would want to jump to for F, E and L respectively? Let me know what you all think, thanks.

Go back to shbox and look up how to build an adapter cable.

 

I thought the ABS scanner that they use at the dealership had actually activated the pumps and solenoids to determine what was wrong with the system and get the codes.

 

I'm sure they do, too bad I will NEVER go to a dealership after they asked "are you sitting down?" before quoting me $2800 for an opti ten years ago for my 94Z. Not to mention they will surely charge $100 to diagnose a problem I expect to fix for less than that. Sorry, but I hate the stealer and I never tire of calling them by their proper name.

 

My scanner only has the A, B and G pins. Connecting A to pin 5 seems fine since they are the grounds. I have a pin 9 since it is an OBDII style connector, but there is no pin M on my scanner. Should I try using the B (diagnostic terminal) to pin 9 (serial data)? Can/will this screw up the system?

The scanners used by dealers and good shops are bidirectional test tools that besides reading codes can mimic the output of the ECM/PCM and manually control all parameters normally controlled by the computer. And, yes, they cost thousands. Improper use of these tools can really scramble the brains of the computer, so be careful.
