What does code P2DA5 mean?

Q: What does code P2DA5 mean?

Coolant Heater A Supply Voltage Circuit. P2DA5 indicates that the powertrain control module has detected an abnormal voltage condition on the supply circuit feeding the coolant heater, which is an electric element used to warm engine coolant for faster cabin heat and reduced cold-start emissions. The computer monitors the voltage on the heater's power feed and sets this code when the signal falls outside the expected range for the current operating conditions.
