How to resolve the P0597 trouble code in Cruze?
1 Answers
P0597 trouble code can be cleared by matching and erasing with a computer at a 4S shop. The P0597 trouble code, applicable to all automobile manufacturers, means Thermostat-Heater-Control-Circuit/Open. Relevant information is as follows: 1. Function of the thermostat: The function of the thermostat is to close when the coolant temperature is low, allowing coolant to circulate only within the engine to speed up warm-up. 2. Fault: When the water temperature exceeds the set temperature, the thermostat opens, allowing coolant to circulate to the radiator, effectively improving cooling efficiency. This trouble code indicates that the electronic control unit (ECU) has detected that the voltage of the thermostat heater control circuit is outside the calibrated normal range. Possible causes include the thermostat heater, its circuit, connectors, relay, or electronic control module.
