C0579, C0584, C0589 or C0594

WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

The following conditions may cause an intermittent malfunction to occur:

There is an intermittent open on the actuator control or supply circuits.
There is an internal shock absorber actuator open or high resistance value.
If the conditions for a DTC C0579, C0584, C0589 or C0594 are current, the ESC module will disable the actuator by commanding 0% duty cycle and the vehicle will experience a soft ride condition on the side of the vehicle.
If the DTC is a history DTC, the problem may be intermittent. Using a scan tool, cycle the shock absorber actuator while moving the wiring and the connectors. This can often cause the malfunction to occur.
