Prius Ac Fault Codes. For faults that may not set a code, or for specific faults that seem especially troublesome or common, you should check to see if Toyota has issued a Toyota Prius Diagnostic Tips. Does this mean a change of main ECU or could something less be the cause?
When error codes appear on your Fujitsu Air Conditioner this tells the you there is a problem.
Occasionally, a Prius will just refuse to start normally.
If you had an oil change at the same time, this code I think later model Prius's lengthened the allowable time delay for the engine to start before the code was thrown, but that didn't fix the overfilled oil problem. For faults that may not set a code, or for specific faults that seem especially troublesome or common, you should check to see if Toyota has issued a Toyota Prius Diagnostic Tips. I also checked the fan relays with the scan tool connected, that'* not it.
