My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

If this code came from the heater/ac control panel for the heater/ac system here is the description of this code.

DTC B1315: Evaporator Inlet Temperature Sensor Short Circuit.

This can be an issue with the evap temp sensor needing replaced as this is a common component that can fail.This will cause no ac operation and the service ac message you see here.If this is not the code let me know.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,a rating of 4 or 5 is appreciated.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.
