Hi all:

In the process of trying to find the battery drain, I have basically given up for the near term. I picked up an isolation switch, and want to mount it inside, near the glovebox. The job entails running two new negative wires to the switch, and back to the existing wire and battery. I don't want to mount it in the engine compartment...likely too hot on the exhaust side of the engine.



So, after removing the glovebox, I found these. As I have no manual, I wonder what they are. One is a Siemens module, the other is undetermined. There is a what looks like an upside down filler neck, with a quarter turn cap, and wires coming out. Can anyone ID these for me? I suspect one is an alarm, and the other may be the ECU. I am baffled by the black filler thing. Also, in the last photo of the engine compartment, is this the cruise control module?



TIA,

Pat

not sure about the first shot. its not the ecu. where is that located?



the second one is the diagnostic port, as is the third. this car is OBD1, so the port is weird and none of the cool modern gadgets work on it



the fourth one is the cruise control

Flash,

The first one appears after removing the plywood kick panel on the passenger side. I noticed it after I took out the kick panel and the glovebox. The car has what appears to be an RJ-45 port on the right side of the center console. The Siemens module can be seen horizontally in the second photo. Behind the black capped thing is another module, which I thought maybe is the ECU. I will go out tomorrow with my glasses and a mirror and see what they are.

Thanks!

Pat

That's either your SWX4 shortwave receiver, or the blinker fluid reservoir. <img src="/forum/images/smilies/968/wink.png" class="smilie" alt="" />



Just kidding, I believe that's your door lock control, or "immobilizer", or similar. You can Google the 5WK4 XXX number for more info, most likely.

The Siemens module is the air bag control unit.

The round connector, the one Flash identified as the OBD1 port will accept the Durametrics Diagnostic Tools in either the Pro model or the Porsche Enthusiast Plus model ( 3 cars only). Those models have the 19 pin adapter you need for the round connector on the 1992 through 1995. You can not do every diagnostic test using the Durametrics, but that is the limits placed on by OBD1, not the tool.



Still a great tool for looking at the engine. With that tool and a laptop. Things like how your gas octane is doing and how hard the engine knock sensors are working to send signals to the ECU to retard the spark and keep the engine from self destruction. I have a Plus model and used the first 2 cars choices on 95 and 96 993 engines. I have not yet committed my 3rd car choice to the 968, but I will.



On the 993 engines which have the same compression ratio as the 968 I had the knock sensors going off all the time under full throttle using 91 octane gas. Now when I go to things like DE events I use 3 parts 91 and 1 part 100 octane unleaded to get 93 octane which seldom give a knock.

Thanks! I have to post another photo of the RJ-45 connector. Do any of you have this on your consoles?

KesslerR, thanks for the Durametrics info. I have a house in Tucson also.

i highly recommend the durametric. it has been invaluable.



i just wish we could use some of the cool new stuff that is out there.

thanks.

Sure, PM should be working. I don't know to much about the air bag unit, other then the part number on that picture corresponded with the air bag unit. What's your question?

Did you resolve your air bag issue? Say's you can receive messages - odd.

It appears I hit my PM limit, will have to have one of those Admins fix that.. I haven't fixed my airbag issue yet, it doesn't stay on, but can take anywhere from 1 to 10 minutes for it to shut off. Tried to read it with a hammer over the weekend, and it didn't show any codes, but I'm not confident that the hammer was communicating properly with the car.

I have the same issue. Let me know what you come up with, I will do the same.

My dad always told to just get a bigger hammer <img src="/forum/images/smilies/968/laugh.png" class="smilie" alt="" />

At times I was tempted to do so.

I'm trying to remove my air bag control unit (the item in the first photo of the OP's first post), but two of the nuts are very strange - they're a serrated, sawtooth type of nut. Here's a picture of one, as part of an edge-on view of the control unit:



   



Any idea what type of socket to use to get this thing off? Thanks.

There is a reason for these unts to be installed that way , i always disconect the battery about 1 hour before i start working on them , to deplete the system of al it's power .

Friend of mine lost a college , the airbag went off and he was sideways in the car , broke his neck and that was the end for him .

So just keep in mind when messing around with these systems , that is also the reason they use special locknuts and most of the times they are or you have to destroy them to get the unit out .

Sorry to hear about your friend's friend.



Sorry, I don't know what that "serrated frusto-conical" nut is called, but maybe the folks as McMaster-Carr can help.

I still have my control unit exposed, so I'll take a look at mine today and see if I can provide any assistanace. I agree, some fasteners are not made to be taken off by laymen.

Here is a picture (possibly) of said tool if that helps - on that *other* forum. Our forum doesn't allow that phrase for some reason, so you have to go there and then find
