7, Central Locking Pump, examination:

When reading in the Crossfire forums it can be found that it's very common with a problem with the Central locking Pump. In most cases because water has got into it. I don't think that's what cause the problem with my car, but now when I investigating the anti theft system I can take it apart and look into it and what condition it's in. Don't do this if not needed, big risk to destroy something and it's very expensive.

Take it apart:

The are both wires and air tubes that are connected to this Central Locking Pump. There are three hoses mounted in a block. With a screw driver, pull out the locking mechanism, gently.

When the lock is open it's possible to lift the hose block away from the main body.

These are the C3 and C1 connector. Unlock it by pull the black lock downwards and then pull the gray hook downwards. After this the connector can be gently pushed upwards.

The C2 and C4 connectors. Push the lock arm to the left and pull out the connector. The C2 connector to the left has two of this lock arms.

At the bottom of the Control Locking Pump there is a lid. It's hold in place with a lot of hooks. With two screw drivers I was able to unhook it. Better to use a wider screwdriver or a plastic card.

After it open I can inspect the circuit board, no traces of water damage.

A central small screw hold a sensor in place, don't unscrew as I did !

There also three Torx screws on the other side.

Inspecting circuit board for damage:

The cylinder is the air pump for pressure and vacuum. Note: this is electronic and its sensitive to static charges. Have a grounded board to work on and also a special wrist band that connect you to ground. The photos is just when I take photos.

Complicated device, but some parts can be replaced if broken. The electric motor and the air pump. The relays, capacitors etc.

Inspecting the relays, looks okay.

The two 18 pin connectors, C3 and C1.

Assembling it:

After this examination I assembling it again. The motor with the air pump sits on rubber absorbers, must be in correct position.

The hose that connect the incoming hoses to the air pump must be in correct position.

I don't install the lid now, I let it dry indoors and I will also do some electric measurement on it.

Resistance measurements on C2 and C4 pins relative ground:

Resistance is relative ground, C2 pin 3. No cables attached.
