Hello everybody,
I bought 1995 S320 L US version with some issues. Actually they told me engine was seized and got it at very reasonable price.

Found out that lower engine wiring harness was never replaced. Biodegradable bad wiring. I checked the main engine harness and it seems updated one dated 98.
Anyways i saw an ugly aftermarket switch that turned out direct starter switch. You can turn in ignition with the key but can not crank. This seemed a good news for me considering that engine was seized.

I fixed the lower wiring harness and still not successful to crank the vehicle with the key. Ignition switch seems ok and has enough tension on crank position.

I see that i can use button on remote control and lights are illumination on door handles but power locks are not working. Vacuum soft close doors are working fine. I checked the rear fuse panel and saw number 11 fuse was missing. I put new 20 amp fuse and compartment lights were turned on. I tried to lock the vehicle but no power locks and immediately fuse was blown. When i push lock/unlock button on dashboard it makes a funny steady noise while pushing which seems coming behind passenger airbag.

I tried to scan the car from main port through engine compartment with DAS but it says turn on the ignition even it is ON.

Does number 11 fuse have anything to do with cranking problem or something seperate?

I am open to any suggestions and ideas.

Than You

If I'm right, this is the module that controls the remote central locking and by looking at the ETM schematic it's connected to the Starter lock-out relay module (K38) by a brown and gray wire. Relay also has 4 wires according to the schematic. Seems like a match so far.

This module is also know as the Infrared Remote Central Locking (RCL) module. In the manuals it uses N54 as the reference number.

So if this module is toast, as it clearly looks like it is, then it would be preventing you from starting. Does your central locking work at all? I ask because the pictures I have of the RCL module look nothing like what you've got. Which confuses me, because there is no comfort module in the starter generator schematic.
