A/C Request - Range Yes/No

The Body Function Controller (BFC) uses this input in determining whether Air Conditioning (A/C) is being requested from the HVAC selector. The input from the HVAC selector is received by the Body Function Controller (Body Function Controller (BFC)) and then sent out over the Class 2 serial data line to the Powertrain Control Module (PCM) and Diagnostic Link Connector (DLC). Yes, is displayed when A/C is being requested. No, is displayed when A/C is not being requested. Note: That A/C is requested does not mean the A/C Clutch is engaged. Other variables must be met for the Body Function Controller (BFC) and the Powertrain Control Module (PCM) to engage the compressor clutch.
