Code C0658 Description

The Automatic Level Control compressor is switched ON and OFF using an Electronic Level Control (ELC) compressor relay which is controlled by the Electronic Suspension Control (ESC) module. The ESC module circuitry provides a switched path to ground whenever compressor activity is required. This drive circuit is also continually monitored to determine if the voltage level agrees with the commanded state.
