Looking in that workshop manual again ....
REPAIR MANUAL , BODY ELECTRICAL ....
there's sections on (1) POWER DOOR LOCK CONTROL SYSTEM , (2) WIRELESS DOOR LOCK CONTROL SYSTEM , (3) DOUBLE LOCKING SYSTEM , (4) THEFT DETERRENT SYSTEM
Not sure now if the date option (2001,7_) is much use - seems to just show the sportcross cars :duh:
Fuses mentioned in the LOCATION subsection of these sections are ...
(1) DOME, MPX-B, ECU-IG, DOOR - (3) DOOR DL, MPX-B, ECU-B1 - (4) HORN, ST
The INSPECTION subsections might be a good read too if you're looking for some diagnostics help
Good luck.
