Hi,

I have a1995 buick lesabre. It has a odbii connector, but I believe it
is still obdi (i read that GM used a hybrid system in 1995). I tried
reading it with a friends obdii cable and it wouldn't read.

Is it possible to jump the pins on this system to read back the codes?
If so which pins would I short, then how would I get the codes back.

thanks
chad

No, you need a scanner with crossover capablities on this car.

Chad, DON'T EVEN try to short any pins and put power to the car! It will
destroy the ECM. Your LeSabre has an OBD II connector. You should bring
the car to a shop that has a very good scanner (a large red housing) and
it will display the codes. Only difference between the '94 and '95 to the
'96 is the prefix before the code number(s). Some scanners are unable to
read the codes on GM prior to '96. Try other scanners.

If you hooked an obd-1 'scanning tool' to the connector and tried to scan
your ecm with it, you've already shorted the pins necessary to scan an
obd-1.
