Hi,
I have Rogue 2016 SV. The AC clutch doesn't engage. I tried to do the IPDM test to check the clutch engagement but the test does not start. The engine light is only blinking for few seconds. I checked the clutch by sending direct power to the connector and the clutch engaged. So, the clutch itself is ok. I checked the fuse and it is also OK. The refrigerant pressure sensor has connectivity. So, this sensor seems ok also. The ac has enough refrigerant pressure. I charged it up to 80 ib/in2.

My question why the computer fails to perform the IPDM test and what other reasons could be for the clutch not engaging.

It seems that there is no signal going to the clutch but I don't know what is reason. What else should I check.

The '16's were the first ones to use "Smart FET's" instead of fuses in the IPDM, and I'm pretty sure none of the Smart FET units respond to the IPDM Auto Active test. Nissan eliminated it from the IPDM software on all of the newest designs. God knows why, it was very useful.

The possible culprits vary slightly depending whether you have Auto or Manual A/C, but you can find full information on both types here...

The A/C Pressure Sensor is monitored by the ECM, so most good streaming scanners will have a PID for it. Rule of thumb is that you should see around 1V static and 1.5V with the compressor engaged. Both low and high readings will cause the ECM to veto compressor turn-on. There are also two or three temperature sensors which can cause a non-functional compressor. Both types have an Ambient sensor in the grille and an Intake sensor attached to the evaporator. Auto A/C systems have an additional Cabin sensor in the centerstack behind the A/C controls. Rule of thumb is that all three should read a "middle voltage" someplace between 0.5~4V. Any 5V reading means the sensor (or sensor ground) is open circuit, which means the HVAC will think the car is in Siberia and will veto the compressor.

Thank you Vstar650CL for this valuable information. I will check the temperature sensors. I guess I have a cabin sensor also since the AC is auto.

The last resort will be replacing the IPDM module. Sadly, there is no ipdm test in this generation.
