A peculiar feature of a CPU exists.
I don't have any turbos either. I don't need them. My engine is 5.3L from '03 suburban. The wife's car is a 2010 Equinox with a 2.4L engine. It actually runs fine. The Junker is a 2002 2 slow Jetta. All the dash lights are on. It gets about 30mpg. Fuel costs around $20 every two weeks. Just need to get me to work, XD.
To reach certain modules, you might need a newer scanner or the maker’s diagnostic tool. This can occur occasionally and is frustrating when issues aren’t easily resolved. This highlights one of the many reasons I choose a vehicle that’s 25 years or older.
We don’t have after-treatment systems, but we do have many that do. The Cats are the exception. Good to know. Here’s a recent rebuild at an old family friend’s shop. Can you identify this motor? (I’ll update the photo soon.) I bought a scan tool for around $500 for full diagnostics on all OBD vehicles. A subscription would cover everything, including wiring diagrams, but I haven’t needed it yet. I’m looking for something more advanced—capable of Air Bag and ABS checks instead of waiting until a wheel bearing fails. Now I can pinpoint customer issues much faster, lol.
They continue complicating repairs by limiting access to diagnostic information on the modules. You’d need to invest time searching for a vendor that offers comprehensive scanners, but those tend to be expensive—often around $2000 or more (not sure how long that’s been). A decent $500 scanner can handle most everyday issues, though it may fall short for full diagnostics in certain situations. I encountered a situation where a $6000+ Crap-on Verus (which isn’t great) and a MATCO/OTC Genisys/Determinator scanner couldn’t connect to the ABS module in a Toyota Camry, while the dealer’s tool worked fine—how could I put that? Lol, it’s been a while since I used a top-tier scanner. The work I do is mostly old enough that it doesn’t really matter, and most of it stays with me, thank goodness.
