Hi, this is my first post here so please bare with me.

So, I bought my 2005 Roadster a few months back with loads of problems attached. I’ve been tracking them down one by one and it’s almost back to a factory condition other than some cosmetics and the top.
I’ve been doing research as to why my top doesn’t operate and finally something caught my eye in this post by pizzaguy. The Central Locking Pump. (Blinking Red constantly, no window operation) I had to remove mine because my trunk was waterlogged (replacing the top ASAP) and completely fried it (I haven’t opened it up yet, but given the amount of corrosion on the connectors it seems better to buy a used one). My question is, essentially, is there a bypass to this (such as a resistor mod, maybe? depending on how the pump communicates) since my wiring harness for the pump is shot from corrosion or am I going to have to stick with manual operation until I can replace the wiring and pump? Pics below are from when I took it out.

Also, I have no history on this car so i’m finding out new things about it all the time, pretty sure SKREEM has been modified or removed but I’m not sure how to tell.

 

Thay pump controls more than just the top. I'm surprised you don't have other electrical issues.

 

Thanks for the warning haha.
So far I just need to put my front wheel speed sensors in to get the CEL off. Replacing my rear sensor solved a lot of my problems (spoiler, cruise, ABS, BAS/ESP).

From what I understand the pump just pumps hydraulic fluid to specific cylinders as directed by the PTCM. The pump is just a pump it either works or not.

 

[QUOTE=onehundred80;962905]This is in reference to the Central Locking Pump, not the hydraulic pump.

 

I thought he stated and showed the Central Locking pump, not the hydraulic top pump?

 

The Central Locking Pump has an integrated microprocessor board that communitcates with the Top Module and the Body Control module in a complex conversation that controls the top, wing deployment, window operation,etc.

There is no "Bypass", you must replace the CLP-SSM as well as any corroded parts of the wiring harness. I and others have dealt with this time and again. You need the CLP-SSM as well as last 2-3 feet of wiring harness from another Roadster to get this all working. There is no other option. Also, cleaning the corroded contact pins is a waste of time, even if you get the mating surfaces clean, the crimps from aluminum pin to wire are all corroded and resistive now. Again, the the CLP-SSM and wiring harness from another car.

You may be surprised at the things that are corrected by this procedure.

 

That's unfortunate. Thanks for the information!
(Though I'm curious, if it affects wing operation how come mine still functions? Am I just lucky?)

 

[QUOTE=Tesla;962906]My mistake, that is one hell of a lot of corrosion.

 

The answer depends on what is wrong with the CLP-SSM, the items that fail depend on what damage has been done. I appears the wing will deploy if there is NO communication at all from the CLP-SSM.
As to the top, it will refuse to move if there is impaired as well as NO communication.
