I would like to know if there is, in fact, a computer data connector on this vehicle and if an after market programmer can read codes as well as program engine parameters as in the 96 and later models.

Can anyone suggest a programmer that works??

Thanks in advance for comments!

 

Welcome to the forum.

The ALDL connector is usually under the steering column. Best way to see if a particular programmer can scan for codes is to check their website. But programmers are an expensive way to get little gain. A computer tune like Blackbear does is a better way to go.

BTW most auto parts stores will scan for free.

 

Never head of an ALDL; only the OBD-IIs... but I remember my old '95 tahoe did have a port under the driver's side... it almost looked like an OBD-II connector from what I remember...

hmm learned something new

Yeah, the OBD-I and OBD-II both have one. It's where you plug the scanner in or other test equipment and programmers.

 

I believe the ALDL is the one where you shorted out 2 pins with a paper clip to get the codes to flash on the check engine light... the first 3 flashes were code 12 to tell you had access to the data link and they it would flash out the code number 3times....

 

If memory serves me, I think it was the A and B pins. Made a shorting pin out of a paper clip and duct tape to hold the spacing.

 

aaahhhh... long gone are the days of opening up the little cover on the distributor cap that always seem to be turned back to the fire wall or in some other blind or barely accessible spot to adjust the dwell....or being able to change a fuel pump on the side of the road in the rain because there was enough room under the hood and in the engine compartment to get in and out of the rain....lol!
