Hi,

ATA has bog all to do with immobilisation on MB.
ATA is overridden by insertion of Key, so although ATA may be faulty, Engine will still start and run !!

Anyone can prove this, lock your Car with the Key Button, then unlock with the metal Key Blade and open the door.
ATA should sound, indicators will flash, but if you insert Key in EIS, Engine will start and ATA will silence !!

Cheers Dave

That's true, I've actually done that before with Dad's car, since none of the door locks automatically unlock (I'll get to that once the V-12 is fixed). Siren went off, I put in the key, started the engine, and bye-bye, alarm noise.

Since my EIS is not working, the seat controls will not work. Since there's a short-circuit somewhere, I of course want to inspect the wires running under the carpet. Problem: since the seats are all the way back, I cannot remove the passenger front seat (right-hand side in USA), because the seat rail is covering the rear two bolts.

This thread...

...allowed me to hot-wire the front-back electric seat motor in about 5 minutes, and the seat is now out. Now I can inspect some wires. Thank you, Dave!

New news:

Got the seat out last night and opened up that plastic channel that protects the wires. THEY ARE WET!!! Furthermore, the foam at the bottom of the floor carpet is wet. Not all of the foam, just the bottom of it. Thought, "naw...couldn't be...!" Yep, The Infamous Reed Valve Was Clogged. DAMN IT!! I thought I'd removed it from the S600, but apparently I missed that one.

You know, I think I may have found my problem. Now I've got to just hope that I found it in time.

Dried up what I reasonably could with a couple of towels, and everything in there is now air-drying. Fortunately, we're going to have three straight days of nice, sunny, hot weather. Additionally, that reed valve will be going bye-bye, VERY SOON.

IT LIVES!!


Looks like water was the culprit after all. The car just spent the last three days, with doors and windows open, drying--well, baking--in the sunny, hot weather we've had since Friday morning. Opened up that plastic channel under the passenger seat and rug, the channel with all the wires in it, splayed all the wires out so they could dry, and just let it bake.

This evening, I replaced Fuse #78, which was repeatedly blowing on me, hooked back up the battery, and gave it a shot.

Put the key in. Got an odometer reading; that's good.

Turned key to Position 1. It turned! So far, so good; the EIS now recognizes the key again.

Turned key to Position 2. Again, it turned! Lookin' good so far. Dash lights up, and the headlights came on (I have it set to "Auto"). Of course I got all sorts of dash errors about pre-safety system and SRS, since every seat except the driver's seat is currently out of the car. That's expected.

And now...Position 3. The moment of truth.

VROOM!

YES! It lives again. First thing I did was roll up all the windows in case it was going to die on me again. We're expecting rain on Tuesday :-) Let it sit for three minutes. Still running. Now five minutes. Still running. Time for a short drive around the block. Car did just fine.

Now it is parked in my driveway, instead of on the street where it had been. Now I can put the interior back together at my leisure.

Looks like I dodged a bullet this time. And yes, I *WILL* be getting rid of that F*****G reed valve, very soon!

If any SAMS or relays were under water or even moistened, you should inspect them. Better to clean contacts now and head future wonkiness off at the pass.

That is exactly what I did to mine when I first got it, stripped all 3 Fuseboxes layer by layer cleaned up and nipped all fuse / relay connectors, then doused with dielectric grease as I reassembled.
Similarly, I did all the Multiplugs and connectors under the Carpets, Contact Cleaner, Tweak, and dielectric grease

@cowboyt

/\ /\ /\ If you have time it might be worth doing that before putting the Seats etc back in

Cheers Dave

Agreed, and I did just that while the car was drying out. Took apart the SAM's, fuse box, pre-fuse box, what looks like a CANBUS connector (a bunch of twisted-together brown wire pairs on what electrically looks a bus architecture), and let them and the fuses and all the rest bake in the sun, too. After that, I took a wire brush to every electrical contact, including the fuses, that I could find. Made sure those contacts were shiny before reassembly. New heat-sink grease where called for (i. e. where the factory had put it), all that.

While I had the rear SAM apart, it looked like it had likely gotten wet at some point previously, before I'd owned the car. There was what looked like some older corrosion on the surface-mount chips's contacts, so it's sort of a good thing I was in there anyway. So, all that got (carefully) cleaned up, too. Yep. If I could see it, I cleaned it up. Things are shiny now.

Hi T,

Sounds like you did a good job of cleaning everything up, so should be good for a fair while

I use Silicone Contact Grease" like this :-

http://www.ebay.co.uk/itm/200g-GS-90...QAAOSwM6NZsFoH

I do put it on every connection plug not sure if that's the same as the stuff you use, idea is to keep the buggers from becoming Green am manky in the future

Cheers Dave

Another great treatment is Stabilant - expensive, but works well enough that the military uses it by the drum...
