1. A vehicle, comprising:
a thermal conditioning system including a compressor and a suction pressure sensor upstream of the compressor; and
a controller in communication with the compressor and the suction pressure sensor, wherein the controller is configured to perform a technique to monitor for a low charge condition, wherein the controller is configured to inhibit a low pressure cutoff when the controller is performing the technique, wherein the controller is configured to perform the technique while the compressor is running, and wherein the controller is configured to inhibit the low pressure cutoff only after the controller has first determined that the compressor is functioning properly.
