Built-in Self Diagnosis ?
Hey Buds,
I was reading on the 6th generation site, that there is a "diagnosis program" that runs on the Radio of the Car.
Do the 5th gen Max. have the same option?
IF so...how do i get there?
Is there anyway to check the A/C system through a plug in diagnosis meter?
Thanks for any help...

I don't think so
Check the FSM, there could be another way to test it

There is an auto climate control button....yes. Is that what you are referring to?
- How do i get to the DIAGNOSIS mode?
- The Car has heat, so if i turn the theromstat control to Heat, i get hot air. But it doesn't get cold enough. I suspect a leak somewhere, since i just changed the compressor 2 mths ago.
....Thanks !

Since you have an Infiniti, you don't have manual controls. Infiniti only used the auto climate controls.
To run the self diagnostic, go to page 36 in this link:

Since you changed the compressor, it is possible that you may not have enough R134A refrigerant in the system. If this were to be the case, the self diagnostic cannot detect it. If the refrigerant level gets too low, there is a pressure sensing switch that will keep the compressor from running.
The self diagnostic checks all the duct work and sensors and stuff. There are 4 (?) temperature sensors in the system which could also cause the problem. When you run the diagnostic, make sure you know what the air temperature is around the car so you can compare to the reported sensor readings (part 5).
One of the sections of the self diagnostics (part 3 I think) of the test takes a while to run, so don't start thinking the diagnostic hung up or something.

- -Compressor is turning, and clutch is turning.
- -Changed Compressor & Condensor about 2mths ago....was blowing cold when i changed it
- -I suspect a leak somewhere...(hope it is not the Evaporator)
I will take your advice...and follow those steps...Thank you!
