C4 scan tool
Anyone know where I can find a scan tool for a C4. Abs light won’t shut off and tachometer is reacting erratically. Dealership says they don’t have a tool for a 91and can’t get it.

Tech1 was used by all divisions so call around. Erratic tach is commonly caused be a secondary ignition fault. High resistance at coil, cap, rotor, or wires. I believe the Snap On MT2500 will read abs if it has correct cartridge. If there is a local Corvette or sports car club they maybe able to refer you.

correct you should be able to pick one up for less then 250 bucks. just make sure you get all the keys to make it work. its been a while but K-9 key is the one for GM cars.

Dealer ships are geared towards cars less then ten years old and still under factory warranty. After that it’s a crap shoot to find a tech who is willing to work on it. Then to take a 25 year old car is laughable. Your going to need to learn to do it your self with the correct tools or be at the mercy of a local shop.

As to factory warranty, don't you lose money working on that? If I pay $1000 for a water pump replacement, doesn't factory pay less? Maybe about $800 or $900? Numbers thrown in for illustration. I thought I read somewhere that warranty repair pays less than non-warranty. Not sure if that is the case anymore.

Warranty Labor issued by the OEM is a little over 1/2 the labor assigned to the same task, that is not warranty. IDK why...but it has nothing to do w/the OP's car. His car is out of warranty.

I kick myself every time this comes up. A friend of mine GAVE me what I think was a Snap-On MT2500, he has his own shop and did not need it any more. This was before I had my C4. I had in my office of my old job before I retired, I cleaned out that office and did not think I would ever need it and threw it away.
Are there no new units at a reasonable price that will read OBD1?

Try this one. I have one of these and it works great. This guy does not seem to know if this does anything but turn on but if you can find one of these they work good.

I'd also want a newer car because they are less likely to be rust buckets which means easier faster removal and more familiar means I can get 3 hrs book time and do it in 2. Hard to get familiar with something coming in 1 time every 2 months than 1 every day. It may be a hobby with you to work with obsolete stuff but they are working to put food on their tables

I agree they're easy. And I'd add that I can beat flat rate on most jobs I do on my own C4. but most techs want the high volume/repeat jobs they can get good/fast at.

I have this scan tool...and it is fantastic. It does many of the functions that modern OBDII scan tools do, such as custom, data stream, diagnostic, actuation controls, freeze frame/picture...and a lot more. It's an awesome scan tool and has always worked on all OBD I cars that I've worked on.
