Default Re: Locking System won't disarm with FOB

Since 1983, I've seen this SO MANY TIMES: You are having weird issues, all related to the security system, because you never fixed the initial problem.

Wrong. NONE of those pins are usable. EVEN IF the CLP/SSM was not ruined (it was), you cannot clean those pins.
Because cleaning the pins does not clean them.

What I mean: You can "clean" the pins all you want to, you are wasting your time. The pins are NOT SOLDERED to the wires, they are CRIMPED. There is no way to clean and remove the corrosion between the pin conductor and the wires - see the arrows below. So, not only did the water seep into the CLP/SSM, the corrosion set into the crimps is also a problem. (The photo is low res, I could not find a good photo.)

You MUST obtain the last 2 or 3 feet of the wiring harness and connect it well "up the line". WHY? Why not just cut the cable off two inches from the CLP/SSM?
Because, as water soaked into the wires, it started to set up corrosion on those wires as well, so, if you try to splice on the new harness, you run the risk of "splicing" or "crimping" onto wires so corroded, you have handicapped yourself.

From 1983 to 2011, component-level electronics, often in automotive settings, is how I earned a living. I've seen what techniques work and what techniques do not work. Your only path now, is to replace the CLP/SSM AND the last 2-3 feet of wiring harness - far enough up, that it is beyond where the water got on the wires, and soaked in. Do that, and the car will be the source of joy you want it to be.

I've seen this on four Roadsters since 2009, the story is the same. (While Ive heard of this happening DOZENS of time, I fixed four cars myself, the story is the same every time.)

And keep in mind, the security system, locks, lights, alarm, wing, both trunk locks (the pneumatic and electric), rear window heating element and door windows are all operated by the CLP/SSM or are operated by the BCM in co-operation with the CLP/SSM. You can have all sorts of WEIRD issues with the car that SEEM like are caused by other items, but are unfix able, because the issue is in the CLP/SSM - which no one ever suspects.

In all the help I've given people on electrical issues (Im not a mechanic, you do not want me fixing your brakes), I seldom will make a 100% certain statement, but I will now: Replacement of the CLP/SSM and wiring harness leading up to it will fix it all: All these security-system related issues will end - provided the CLP/SSM you get is not also water damaged. Yes, that is a risk. SO MANY of them get wet....
