Door lock issue on 2010 kk

[daveuk]

Hello all from UK
After some help please with my 2010 KK, It will unlock using fob and Drivers and passengers console, but will not lock
I have changed M38 fuse, which was blown, and can hear relay click when unlocking, and a duller noise when pressing lock from TIPM....any ideas would be appreciated before I go to the dealer !!
Many thanks

Welcome.
Wish I could be of more help...Could it be that the lock relay is bad?
A quick call to the dealer may help, as they may be aware of any known lock issues.
Handy I have an 2008 service manual, have a look at schematics..

Many thanks for the reply, I will have a look at schematics

The 2008 schematics show that there is some form of control box under the passenger seat (LHD?) for the rear door controls...not sure about other doors.
Driver seat has a relevant grounding point underneath.
Logics are not too detailed and everything is driven by CAN Bus from the TIPM!

Thanks for this Billwill....I think I have this narrowed down to a fault with the door lock/front washer power double relay on the circuit board within the TIPM....well out of my league unfortunately...looks like a trip to the dealer
