It makes the SES flash if you jump the right 2 pins. Example: Flash-Flash pause Flash-Flash-Flash-Flash would be code 24 (example, no idea if there is a code 24).

Yes, the SES more than likely holds the key

I understand that.

But what im saying is will any OBD1 scanner from checker or autozone work?

Or is it something fancy? lol

Yours might have the OBD2 connector, and yet be an OBD1 car, and I think that's a problem for some scanners. Advanced, Checker and I think AutoZone as well (I know the first 2 do, I worked at Checker) can scan them.

See, I'm wondering if it's incompetence on their part.


Do you have an ODB2 connector?
Yes? -Are they testing it as OBD2?
No? -Are there scanners capable of OBD1?

If yes: Tell them to test it as OBD1
If they can't: Take it to a shop, usually they'll test free to get you in the door.

If no: See "If they can't"


My scanner that I have, was the same one we used at Checker 4 years ago, and I can swap plug ins and specify if I'm testing OBD1 or 2, even if I have an OBD2 connector on it. I also have real-time readings of sensors and other stuff the E/PCM is seeing

Im gonna try shbox's method with a OBD1 scanner and jumping the wires and see where that gets me. If not that I guess I will have to go somewhere to have it scanned.

I assume this is the method you're attempting (in the Note portion)

I got the PCM scanned to day and I have the following codes being thrown..


23: IAT sesnor, Low temperature indicated
26: EVAP Purge Control Circuit Fault
37: TCC brake switch errorm TCC Brake switch stuck on
51: Faulty or incorrect PROM/EPROM


37 could be caused by the B&M Shift+ thing module I have.

26 states its a wiring error

23 I dont even know how I could have low temp indicated when I dont even have a CAI lol

51 could that be my tune??
