C0577, C0579, C0582, C0584, C0587, C0589, C0592 or C0594
WARNING: This page is about a different car, the 2004 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
In order to test for the conditions that set a DTC C0577, C0579, C0582, C0584, C0587, C0589, C0592 or C0594, the ESC module must first command the actuator ON. The ESC module must be in a command ON state. If a low voltage level is detected in the actuator control circuit during the ON state, the test is again repeated. If the ESC module determines that the voltage levels detected in both tests are lower than expected, a malfunction is present and a DTC will set.
