I was looking through FORScan on the car for the first time in a while and noticed I had 4 codes.
3 were in the BECM:
P0AC9 - Hybrid Battery Temperature Sensor B Circuit Intermittent/Erratic
P0C8C - Hybrid Battery Temperature Sensor 1 Circuit Intermittent/Erratic
P0C91 - Hybrid Battery Temperature Sensor 2 Circuit Intermittent/Erratic
I also had P0C4A in the PCM which I have seen before for "Hybrid Battery Pack Coolant Pump Control Performance". The heater coolant pump was replaced last year under warranty when it failed. Same code was there then.
I'm not sure what would causes these. No Freeze Frame data with them. I thought about clearing and seeing if they came back but if there's some reason I need to take it in let me know. Its under the ESP extended warranty with $0 deductible so as long as there is something to repair its free for me to bring it in. Otherwise I'll clear the codes and see if they come back.
I also had a U0100 in the ABS module for lost communication with ECM/PCM but I don't think that is anything important.
