PEOPLE SEE YOU DO THIS DIAGNOSTIC ,, BUT DON'T KNOW WHAT GOES INTO THE BACKGROUND WORK THEY THINK YOU JUST PLUG A SCANTOOL IN AND IT MAGICALLY GIVES YOU THE PROBLEM ANSWERS AND THE FIX. THANKS FOR YOUR TIME 🙏🙏🙏👍👍👍

Spot on. The "machine" has all the answers!! hahaha. Thanks for the comment 👍

I had an older altima kick my behind with that same thermistor problem. Thanks for sharing.

Nice had a Cadillac today with about 20 u codes. Cause of your videos i found the lift gate module under water in the spare tire well

Awesome. I have seen a lot of bad refrigerant pressure sensors going bad. The same thing i have variable resistor i adjust the voltage to 1.4 volts or something in between and everything works assuming i have good 5v and ground. And it will never set a code. Thank you and waiting for more videos.

Good point on the pressure sensors. Most Nissan's the pressure sensor is in the front, condenser area. They get damaged frequency in collisions and overlooked during diagnosis.

And also as an aftermarket scan tool user.. it is awesome that the consult lets you view pids from different control modules at once. That can give immediate direction as to where to start!

Great info, Thanks! Just another reason why I hate working on Nissans, would it really be so hard for them to include a PID for that sensor? There code description is also terrible, I unplugged a COP coil on a 2019 Infiniti and the only code I got was a P0300!

sometimes you may have to unplug more than one to wake up the misfire monitor. Othertimes the misfire monitor won't run until in gear or under a specific load.

The determination of manual/auto has always been: Automatic has temperature settings. Allowing you to set a temperature. Manual has a red/blue scale without temperature setpoints.

great video. Question: Was there not a pid on scan data showing thermistor reading at evaporator? Keep up the great work

No PIDS, That AC control head does not even communicate with the scan tool, gotta go old school testing on it.

Auto vs manual ac ... I understand the difference is in temp controls. If you can set the temp to 68 deg, the HVAC control module will apply heat or ac and actuate blend door modes automatically to achieve your golden set point. Manual ac is a blue and red knob where you gotta make those adjustments on your own. The blend doors and temp doors won't move as the cabin temp changes. The auto system is also a feedback system that has a cabin air temp sensor, similar to an oxygen sensor feedback system.

That is a great assessment of the systems. I think they should re-word "manual" AC to "semi manual" or something 🤣😅😂 to keep down on confusion. Thanks for commenting .

@@CartersDiagnostics that makes sense. And a full manual system would be old school with cables to manually operated blend doors? Do any new cars still use cables though?

@@ablackformula I don't know 100%, but I doubt any manufacturers are using cables these days.

Great analysis and explanation. I always have a hard time on Nissan😅. Just one question on this case study. Does the Auxillary fan here also didn't turn on with compressor?

The inside blower motor worked fine. The outside cooling fans did not come on, unless coolant temperature got high. Once the car was fixed the outside cooling fans worked when the compressor cam on.
