A/C Request

Range: Yes/No
The BCM uses this input in determining whether air conditioning (A/C) is being requested from the HVAC selector. This input is sent out over the class 2 serial data line to the following locations:
^ The PCM
^ The data link connector (DLC)

YES is displayed when the A/C is being requested. NO is displayed when the A/C is not being requested. Note that A/C being requested does not mean that the A/C clutch is engaged. Other variables must be met for the BCM and the PCM to engage the compressor clutch.
