Set Condition

This DTC is set whenever the A/C Cool-down Test has been aborted or failed due to one of the following conditions:
- The test was aborted because an Evaporator Temperature Sensor DTC is set.
- The test was aborted because the A/C Compressor did not engage within 10 seconds of being requested or the A/C compressor was disengaged during the test.
- The Test failed because the desired refrigerant pressure, as communicated via Controller Area Network (CAN) by the Powertrain Control Module (PCM), and temperature drop, as determined by the Evaporator Temperature Sensor signal, was not achieved within a calibrated time limit.
