Power module over current detected by software
â–¶ How to fix
Check the three phase cable and compressor motor terminal for short circuit among the phases. If no short circuit, Check for compressor high pressure operation or stalling or blocked operation. This can be done by checking the refrigerant circuit for blocks or faulty valves.
What you'll see
No driver-visible symptom recorded.
System reaction
System enters error mode and switches OFF
Diagnostic depth
Detection
The internal current sensor measured a value higher than the current limit of 72A Peak on the output AC side
Possible cause
Short circuit between phases either in AC cable or in the compressor terminals. This DTC may occur also because of stalling or blocking of compressor due to high pressure in the refrigerant circuit.
