Hi - need some help on ETM interpretation and tests - can't see wood for trees at the moment. Fault - Passenger door will not lock by remote or key from driver's door or boot. However, inserting key in passenger door will lock/unlock both doors and boot. One way traffic! I know usual suspect is boot `loom of doom' but I inserted a new DIY section of loom (~18months ago) and all- worked Ok until now. Have checked continuity on inserted section and all seems ok. Removed passenger door card today and revealed part of door loom (see pic) but unable to work out which is input signal wire and which is output. Also don't know what voltage I should be seeing. Any ideas please?
