This Diagnostic code is the result of two or more HVAC actuator related faults being active. The body controller prevents A/C compressor operation when this DTC is set. . NOTE: If a problem is found in two or more of the actuator circuits, repair those circuits and clear the diagnostic trouble code.Now, start your car, turn on the AC, and observe the gauge readings. For most systems, a normal low-side reading will fall between 25 and 40 psi, while the high-side will range from 200 to 350 psi. If the readings are significantly higher, it may indicate an overcharge.

DESCRIPTION: This fault code sets when there is a short to ground in the turbocharger compressor inlet temperature circuit. MONITORED PARAMETER: Turbocharger. Skip to content. whatsapp +51955515985; [email protected]; 24/7 Customer Support;One way to check the diode polarity is to use a meter on the ohms scale. Unplug the compressor clutch from the wiring. Put the meter on rx1 scale. Put the red lead to one wire and the black lead to the other. You should read a low ohm reading, or you should get a very high or no reading.May 5, 2017. #9. AC clutches have an air gap between the the rotor and stator. The magnet in the clutch overcomes this gap, and brings the two together, making the compressor spin. If the gap is to large the electromagnet in the clutch can't do its thing. Low refrigerant is a common cause of no clutch engagement.

Use a digital voltmeter to measure the ground and voltage of the battery at the detached connector cable. Go on to check the fuse if you cannot read the voltage readings. Move on to the clutch relay if the fuse turns out fine.91.1 SPN 2629/FMI 3 This condition is typically open circuit or short to power. 91.1.1 Open Circuit/Short to Power Check Check as follows: 1. Turn the ignition ON (key ON, engine OFF). 2. Check for multiple codes. [a] If codes 1636/3, 2629/3 and 412/3 are active at the same time, go to step 3. [b] If only fault 2629/3 is active, go to step 5. 3.A damaged or seized A/C compressor can prevent the clutch from engaging. If the compressor is not spinning freely, it will be unable to engage the clutch. 6. Broken Drive Belt. The drive belt connects the A/C compressor pulley to the engine. If it breaks or becomes loose, the compressor won't turn, and the clutch won't engage.
