The Bendix+ SMS-9700 accessory solenoid manifold is a bank of low air flow solenoids used to control devices such as suspension dump, differential locks, transmission controls and other piloted chassis functions. Each solenoid is controlled by an electrical switch inside the cab of the vehicle. Identifying the type of solenoid is essential for servicing and troubleshooting. Note that the individual solenoids in the bank can be replaced, but not repaired.
