Yes, I understand. What signals the ECM to generate 5V at pin 14? Based on the schematic, I see three signals sent to the ECM - from the HVAC control module, from the low pressure sensor through the HVAC control module and the fuse block. We confirmed the a/c comp relay is working by testing pin 43 which leaves the other two as options unless there are other inputs that send signals to pin 43. Please advise what you recommend as your next step?
