Suspension strut valves -N148-, -N149-, -N150-, -N151-
The suspension-strut valves (also referred to as transverse check valves) permit raising and lowering of the vehicle.
The suspension-strut valves are activated by the self leveling suspension system control module. The valves are grouped together in a solenoid valve block.
These valves take the form of 2/2 way directional valves and are of the normally closed (NC) type.
