Automotive RepairDiagnostics & Troubleshooting3MediumMechanic$ implied

After replacing the expansion valve, the AC compressor cycles on for 1.5 seconds then shuts off, requiring ignition cycle to restart, but no diagnostic codes indicate the root cause.

Existing scan tools cannot read the AC pressure sensor value on this vehicle, preventing diagnosis of whether the pressure switch is faulty or the PCM is incorrectly commanding the compressor off.

Workarounds Described

  • jumps the AC relay to force compressor on to verify system works

Implied Software Gaps

  • software that reads proprietary AC pressure sensor data via OBD-II to diagnose compressor cycling issues without a high-end scan tool
App Concept

AC Diagnostic Pro

A mobile app paired with a Bluetooth OBD-II adapter that reads proprietary AC pressure sensor data on Ford/Lincoln vehicles. It displays real-time high/low side pressures, evaporator temperature, and clutch command status, allowing mechanics to quickly identify if the issue is a faulty sensor, wiring, or PCM logic without a high-end scan tool.

Key Features
  • Reads real-time AC pressure sensor data via OBD-II on Ford/Lincoln vehicles
  • Displays compressor clutch command status and evaporator temperature
  • Logs data to identify intermittent failures
  • Provides guided diagnostic flowcharts based on symptom and data
Target Users: Independent mechanics and DIY enthusiasts working on Ford/Lincoln vehicles, especially those without dealer-level scan tools
Revenue Model: $19.99 one-time app purchase plus $9.99 for vehicle-specific diagnostic add-ons
