Code C1726 Lincoln Description

The Vehicle Dynamic Module (VDM) will command the air compressor and air solenoid valves to either fill or vent the air springs depending on the input from the 3 height sensors. The air compressor sends the air to the air springs first through the drier, then along the air lines, passing through several T-fittings and connections, through the air solenoid valves and finally to the air springs.
