Thanks Kevin , I scanned a 2010 Chrysler Town and Country today with my IM 508 and through live data was able to determine that the AC pressure transducer was reading too low of a pressure compared to gauge pressure for the PCM to see to activating the cooling fans to pull air through the condenser. A $49 Santech MT0694 AC pressure transducer from autozone with a one year warranty seemed to do the same trick as OE one that lists for $124 from Chrysler which costs double to help offset some of their warranty units :-))
Wow, Guess I saved enough $ going aftermarket to pay for AutoAuth for 18 and up models for a year, however I think I'ld rather use the bypass cable for awhile and cause some annoying dash rattles to convince folk to buy another make of car that don't make the mechanic jump through hoops to fix their car or cost them $50 a year and and keeping an active update subscription on his tool just to scan one.
I did go into Immobilizer (for Fobik key) and was easily able to pull and record the immobilizer password for my customer for future reference if he wants to add another Fobik key later, and then I can add the new key later with my regular go to MaxiSys Elite.:-)) You never know if or when they will start downgrading the IM tools, where and it won't actually display the passwords/ PINs any longer and instead be hidden and encrypted relying on a AutoAuth LSID Enema of private information and another $100 or more down the drain:-((
So I will pull as many PIN numbers as possible while I can for my customers for future reference while the getting is still good on them .
