Trunk pull down doesn't work.

[The Owner]

Hi,
I've a 2003 Cartier and the trunk pull down don't work. I've to close the trunk by hand, it close/lock the trunk the last bit as normal. I've to open it with the key, if I try to use the open button on the door or remote keyless I can hear a "click" sound inside the door, but the drunk doesn't open.

Also the light inside the trunk doesn't work (I've checked the bulbs).

And I've fault code B1342 ECU IS FOULT.

I've checked the fuses.

What could be wrong, any suggestions?

Thanks

Thanks mrzeee for your reply.

I'll try to do the pinpoint tests to see if there might be a bad connections.

Sorry but what is a LVC?

Where can I buy the part(s) (if they are broken), part(s) needs to be shipped to Sweden.

Thanks

Hi,
Is this the lid module?

Thanks

 

[The Owner]

I did some pinpoint tests,

I checked the power and the ground to the lid module - all ok.
And did verify the integrity of the luggage compartment lid motor - all ok.

For me it look like it's the lid module that are bad.

Any suggestions?
