yes, the Tech 2 is used for this.

This is an old comment, but I recently used my Tech 2 to diagnose my son's 1995 Buick Park Avenue with the 3800 engine. It worked fine and we ended up replacing the PCM.

@@raykawal Did you go new pcm or a used one? Did you use the tech 2 to program the pcm to match up to the car?

@@fuzzymoto896 We bought a used one and we didn't need to do any reprogramming. The car ran perfect after the replacement.

There is no adjustments that can be made. You didn't state weather you have a the 2.0 turbo or 2.5l but both have no adjustments, they are sealed, they calibrate on their own. The only thing you can do is clean it. If it is not working, idle is to high or to low, setting codes, all you can do is replace it. Make sure there are no intake manifold leaks if the idle high or low.

TECH BILL with the tech 2 u have to input the options for the car, they can be found by the rpo codes that r on a sticker in the clove box or the gm parts department, if the car has a security key that needs to be programmed also

no they are compatible for GM, some Isuzu, Saab, and Toyota vehicles (programming verities) and not the newer GMs that use the GDS

If memory serves me. Those key have a resistor in them. Little black chip with connections on both sides. They are not programmed. There are, I think 13 different resistance option for the key. Wrong resistance. No start. Bypass was to put a resistor on the wires going to the key. If it does not have black chip looking. The next gen keys held a black bar and the key was programed and the programing was based on the bidding of the key, so no key or a different key would let the fuel pump run. That key has no chip. Programmed the same as the next gen key. These have a stamp on the key. I believe it's said PK. These have a transponder chip in the head of the key. Programing for those keys are like this: with a good charged battery, put the new key in the ignition and crank the vehicle. Then leave the key in the ignition and on. The key light will now flash... in 10 minutes it will stop. Then turn the key off, crank the engine again, leave the key on again. The light will flash for another 10 minutes. Once it stops again. Turn the key off, now start the car. Keys are programmed. All the tech 2 would do is give you a bar that counts down. Just watch the flashing light.

Nothing I believe. Obd2 came out in 96

@@tysprojects2571 there are 94 and 95 GM's with 16 pin OBD2 connectors and OBD1 computers/ I have a 94 Bonneville with this config...referred to as OBD 1.5

idk i need to know
