Central lock problem
Hello
I have replaced the central lock pump unit. The pump works normal, but only open/close the fuel flap. From dissecting the old unit I find a solenoid that seals the main connection for doors & luggage compartment. This solenoid doesn't get energized from the circuit board, hence the vacuum or pressure doesn't reach the locks. Can someone point me to what connection that has to be active to make the solenoid operate?
