Solenoid Valves

* Only if the system does not use an over voltage protection relay.



** Vehicle specific see chart for details.
In the last column the number of solenoid valves in a system are listed. If there are only three valves listed it means there isn't a right rear valve and therefore no wire in Pin 19. If a wire exists in Pin 19 it will mean the system has four solenoid valves.
