In order to test for the conditions that set DTC C0579, C0584, C0589, or C0594, the ESC module must first command the solenoid OFF. If the voltage detected in the damper control circuit during the OFF state is between two preset values, the test is repeated. If the ESC module again detects voltage between two preset values, a DTC will be set.
