However specific troubleshooting steps will vary depending on the vehicle.
Engine coolant thermostat heater control circuit high voltage.
The driver is equipped with a feedback circuit that is pulled up to a voltage.
The p0599 code is stored when the pcm detects an abnormally high voltage reading from the thermostat heater unit.
If greater than the specified value test the control circuit for an open high resistance.
The ecm can determine if the control circuit is open shorted to ground or shorted to a voltage by monitoring the feedback voltage.
What does that mean.
The ecm supplies 12 v to the thermostat.
The codes p0597 p0598 and p0599 all refer to an electronically controlled engine thermostat.
Remove the electrical.
The ecm controls the engine coolant thermostat heater by grounding the control circuit with a solid state device called a driver.
The engine coolant thermostat heater controls coolant flow and regulates the engine operating temperature.
The ecm controls the engine coolant thermostat heater by grounding the control circuit with a solid state device called a driver.
The driver is equipped with a feedback circuit that is pulled up to a voltage.
