DTC C0716 of C0717
Circuit Description
The air suspension inlet valve is controlled by the air suspension control module. The air suspension control module provides a switched path to voltage whenever inlet valve activity is required. The air suspension control module monitors the inlet valve circuity to determine if the voltage level agrees with the command state.
