The Combination Control Module N10-3 is located - on left had drive cars, on the right side of the engine compartment next to the battery. If you wish to send me your email address by private message I can send you a picture of it.

 

This help?

Thanks curro 101. No 12V+ at the relay on the pump. My car does not have a fuse next to the pump as I have seen in various photos. I can only assume that it is in the fuse box under the hood?

 

According to the fuse diagram, the 40A fuse at number 24 in the engine bay is for the hydraulic unit.
What does the red button in the centre console do when pushed?
Do the windows lower?
Does the trunk lid open?

 

The windows (both front and rear lower.
The trunk lid can open and the red button remains lit after the trunk is closed - this tells me that S69/7 and S69/8 is not activated?
I don't hear the pump at all. Def. electrical supply issue. no 12v+ at the relay when the switch is activated

 

Thanks guys.
Fixed my problem. Cleaned all the connectors at the K40and CCM. Restored power to the switch:grin:

 

Does anyone know if this N10/3 CCM is the same for the face lift model. I have a 2002 which I need to some how bypass the boot micro switch that operates when the boot divider is pulled to enable the roof to open.

My problem is that I cant open the boot as lock is seized and now cant open the roof as the divider is not pulled up.

Long story by I did manage to open the boot by opening the roof and then trip the boot lock ,,happy days or so i thought .

Put the roof back up and then accessed my PSE pump but needed to retract the divider. Great so far,,,then I stupidly closed the boot which had locked again. No problem I thought.... I will do the same again but......this time the roof wouldn't open because I hadn't taped down the micro switch . Damn damn and damn again!!!!

Hence my question.

I did find the answer to how to do it but I feel this was for the pre facelift model so the wiring might be different and just needed some confirmation. Its PIN 54 apparently the grey wire with the violet tracer. OMG HELP!!!

Any help would be most grateful

Regards Steve

PS It also said the micro switch S69/10 can be bypassed through the Star Diagnostics... can any body confirm this please? Forum member i860 has be helping me so far but doesn't think his Star has the right programme to do this.

According to my files there is only one wiring diagram for the roof whatever the age of car you have. And yes, S69/10's sole purpose in life is "To connect ground signal through to combination control module (N10-3) when retractable luggage cover is closed in order to release the Vario roof opening/closing function." You are right in that S69/10 connects to pin 54 of N10-3 with a Grey/Violet cable and the microswitch connects between this cable and the W7 ground.

 

The pinouts and colors didn't change at the facelift - Pin 54, GYVT is correct. Don't need to disconnect or remove anything - just back-probe and jumper pin 54 to ground.

 

It has by far the single largest connector in the box. For pin placement, see post 20 at http://www.slkworld.com/slk-r170-ge...170-general-discussion/313393-slk230-roof-doesnt-work-not-sure-where-start.html

 

To complete the story using Silkie as a model, here is a diagram showing the pinouts of N10-3 and a series of photos showing where N10-3 is located (note Silkie is a RHD car):

Under the bonnet beside the battery is a box of electronics that contains N10-3 (together with other components such as the K40)

Taking the lid off the box shows a number of modules and one or two wires ...

This is N10-3 outlined in green:

If you gently tease the wires apart along the centre line on N10-3 you can see the cable you need (you may need to cut the cable tie to get more access):

N10-3 pin 54 is the fourth pin (second wire) from the left on this part of the connector as shown with the arrow:

The 'magic' that I did for @steve pring was to use a multimeter lead to touch the metal connector at the end of the wire in pin location 54 and press the other end to the negative of the battery (you can use the ground point on the wing too). Holding the wire in this position Steve was then able to open the boot using the switch from inside the car to the point that the boot lid was fully open. He could then unlock the boot catch from the inside and pull the luggage cover into place.
