I've been trying to resolve why the RSM and SCLM modules are not responding in SDD. i just noticed Trosty posted his vehicle spec output and has the same condition. So is this common to all X350's or do we both have the same fault in the modules or wiring?

I'm a complete novice in multiplex wiring systems and its driving me crazy trying to fix. Ive been using the 2004 electrical guide and some of the student diagnosis guides but its a steeeep learning curve. Can anyone help with ideas where to look and what to look for?

 

Not only those but what are:

RATC
ACC
ASU
FETM
ATC
ARM
PAM
ISM
RSM

I have worked out the following so far (I think?):

Serial Data Link:
ADHLS-L = LH Headlamp Leveling
ADHLS-R = RH Headlamp Leveling
TCM = TRansmission Control Module
ECM = Engine Control Module
IP = Instrument Cluster/Pack
ABS = Adaptive Brake System Module

SCP:
DSM = Driver Seat Module
SCLM = Steering Column Lock Module
DDM = Driver Door Module
FEM = Front Electronic Module
EPB = Electronic Park Brake Module
REM = Rear Electronic Module

D2B:
CPM = Cellular Phone Module
VACM = Voice Activated Control Module
AMP = Power Amplifier
NAV = Navigation Module
RETM = Rear Entertainment Module

Any help filling in the blanks or confirming what I already have is greatly appreciated.

 

Here you go

RATC - Rear Automatic Temperature Control (cabin A/C-heater controls)
ACC - Adaptive Cruise Control
ASU - Automatic Suspension unit
FETM - Front Entertainment Module
ATC - Automatic Temperature Control (cabin A/C-heater controls)
ARM - Automatic Restraint Module
PAM - parking Aide Module
ISM - Intrusion Sensor Module
RSM - Remote Start Module

I think the other codes are correct. You can find most acronyms here

RSM is NOT a remote start.

RSM is a RearSeatModule, it is not fitted on XJR, so no responce from it.

 

Thanks guys for the information, So now I can pinpoint exactly what my SDD says I have in good or bad order, What I should have fitted and what isn't fitted.

It's all still a little confusing at times.

 

Thanks for that infromation I was puzzled what the rear seat module could be on the XJR. Also thanks for correcting my cut/paste error for a wrong acronym.
