Engine coolant thermostat heater control circuit high voltage.
What the p0599 code means.
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 ecm supplies 12 v to the thermostat.
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.
Test for less than 5 ω between the control circuit terminal 43 x1 at the k20 engine control module harness connector and terminal 1 at the e41 engine coolant thermostat heater harness connector.
P0599 engine coolant thermostat heater control circuit high voltage.
The ecm supplies 12 v to the thermostat.
Thermostat heater control circuit open.
What does that mean.
P0598 engine coolant thermostat heater control circuit low voltage.
The driver is equipped with a feedback circuit that is pulled up to a voltage.
This is a generic powertrain diagnostic trouble code dtc which means it covers all makes models 1996 newer.
P0597 or p0598 can be set by a short to ground condition or an open or high resistance condition.
However specific troubleshooting steps will vary depending on the vehicle.
If greater than the specified value test the control circuit for an open high resistance.
The codes p0597 p0598 and p0599 all refer to an electronically controlled engine thermostat.
The ecm controls the engine coolant thermostat heater by grounding the control circuit with a solid state device called a driver.
P0559 can also be set by a short to voltage condition.
What does that mean.
The ecm controls the engine coolant thermostat heater by grounding the control circuit with a solid state device called a driver.
Thermostat heater control circuit high.
The ecm can determine if the control circuit is open shorted to ground or shorted to a voltage by monitoring the feedback voltage.
