DTC C0578, C0583, C0588, or C0593

In order to test for the conditions that set DTC C0578, C0583, C0588, or C0593, the ESC module must first command the strut actuator ON. If the voltage detected in the damper control circuit during the ON state is greater than a preset value, the test is repeated. If the ESC module again detects voltage greater than the preset value, a DTC will be set.
