Renault Df1070 ^new^
: On older forum threads, a common tip to prevent the code from recurring (after clearing it) is to avoid using the blower fan on its highest setting (e.g., keep it at 3 or lower) to reduce the initial load on the compressor. Common Causes & Solutions Likely Cause Diagnostic Action Software Glitch Error persists after gas refill. Clear the code with a Renault-specific diagnostic tool. Faulty Connector Inspect the plug on the compressor. Clean terminals or replace the connector. Pressure Sensor Check live data for refrigerant pressure. Replace the sensor if it reads 0 or abnormally high. Compressor Clutch Test if the clutch gets 12V but won't click. Repair internal thermal fuse or replace compressor.

A malfunctioning refrigerant pressure sensor (trinary switch) may send incorrect data to the ECU, causing it to "lock" the compressor.
The Engine Control Unit (ECU) constantly monitors the power consumed by the A/C compressor (measured in kilowatts).
