Code P0517 2015 Toyota RAV4 Description

The battery temperature sensor built into the generator control ECU assembly detects the battery temperature. A thermistor is integrated into the battery temperature sensor, and the resistance of the thermistor changes according to the battery temperature. The resistance of the thermistor increases as the battery temperature decreases and decreases as the temperature increases. The generator control ECU assembly reduces the amount of charging current based on this signal in order to protect the battery. The Diagnostic Trouble Code (DTC) will be set when the battery temperature sensor output value is abnormally high for 0.5 seconds or more with the ignition switch ON.
