Are these things any good? What can I do with it? Looking for something for pre-OBDII cars/trucks. I've seen a bunch on eBay, but I'm clueless what to look for...talking about MT2500, Modis, etc.
Depends on what you want to do with it,and on what type of car.
The scanner itself isn't real valuble,it's the software/cartridges that cost!
Most european stuff requires a mnfr specific cartridge,which is pricey,and pre OBD2 requires mnfr specific adapters.
Latest non programable cartridges stopped in 2001,anything newer needs a programable one that costs @900 each for domestic/asian,updated every 6 months at 495 a pop!
Go w/ one on Ebay that has OBD2 capabilities,with as many personality keys as you can get,they plug into the scanner to access different vehicles.
Depending on how the carmaker set up the PCM,BCM, etc,you can read codes,clear codes,access a diagnostic trouble tree {w/troubleshooter cartridge} read battery voltage,rpms,O2 sensor voltages,fuel trim,coolant temp,pretty much any info sent by sensors to pcm.
If you can get to the Bcm,you can check interior lights,power locks,other body accesories thru the scanner.
If all you want to do is read codes on Obd1,most times you can jump a wire somewhere,and either count idiot light flashes,or hook up an anolog voltmeter and count the sweeps or the needle
I bought a used MT2500 off the Snap on truck 3 years ago,current to 2000 Asian/Domestic,probably 12 or so adapters,complete set of keys,manuals,case for 1500,probably isn't worth half that now!
