Power module i*t load error
â–¶ How to fix
If the DTC count is high, check the compressor for overload or high pressure operation for long. Check by Swithcing ON the AC and running the compressor. If compressor switches OFF after 5 to 10 seconds, with same DTC, check the refrigerant circuit of the compressor for blocking.
What you'll see
No driver-visible symptom recorded.
System reaction
System will enter error mode and switch OFF
Diagnostic depth
Detection
The i*t counters' values exceeds the set Hardware threshold value. The current is integrated over a period of time.
Possible cause
Overload at the inverter output. This could be because of high pressure operation of compressor with cooling circuit valves closed. This can also happen because of compressor stalling or rotation blocked.
