Greetings. I am busting this issue out into its own thread because it is perplexing. I have a 2008 gts.

I have an issue with traction control. The symptoms are:

1. Error codes 052c and 2053 on the durametric. These are “cannot connect to traction control module”.

2. The traction control and sport switch are lit up. They do not control anything and I can’t get either to work.

here is what I have done:

1. I checked the wire bundles for moisture on both sides. Everything there is fine.

2. I replaced the traction control module. No dice - still cannot communicate with the new one. Whatever it is caused me to waste $400 on a new module.

3. I went to the dealer and they can’t find anything.


so, what could cause the issues? I am stuck right now.

any and all help would be appreciated.

 

Welcome to the forum! Sorry it has to be under these circumstances.

On #1 - I assume you're referring to the under-carpet wire bundles in the front seat area? Is it possible it had been wet at some previous point in time? Usually you can spot clues if it had been (dried dust clustered together from the water..)

On the durametric - can you check the "state" of the functions in the traction control module?

 

I can not communicate at all with the traction control module. Nothing comes up on durametric at all. It just says no communication at all.

I will check the wire bundles again to be sure there is no water, I didn’t see anything the first time I looked.

Thanks. This is a weird issue. I guess it doesn’t happen often. Usually there is all kinds of stuff available on the internet, but this issue has nothing.

 

I checked everything and about all i get is on the input informaiton screen it says "not switched" or "Not OK".

I am pretty lost here - there has to be something causing this and it has to be elecctric. I have an after market radio in this car (I did not install) any chance that is messing with this?

How about a wire cut at the transfer case motor? I looked around down there but could a lack of communication with the motor do this?

 

Check the fuse for psm.

 

Something weird perhaps - I watched a russian guy discuss the traction control module fuses on youtube. He indicated I should have 22,23,47 on the drivers side and 7,40,57 on the passenger side.

I have 23 (30 amp) and 40 (10 amp). I do not have 22 or 7. Should I? That would cause issues wouldnt it?

 

I'm not familiar with 08 fuse layout and I believe that is year specific.
There are several CU's that have a play in traction control.
Porsche doesn't call it traction control so when Durametric refers to a system and not a subsystem I'm not sure what is meant by "traction control module".
It's fairly simple in that if the CU has power and is operable then you should be able to connect with competent software. I am not familiar with Durametric as I do not use it.

 

2053 is a Porsche Specific code for the transfer case CU. No communication.

 

correct. I am trying to diagnose what is stopping that communication.

I put in a new transfer control module but the Porsche tool couldn’t see either module (I HD the dealer try).

so now something else is blocking communication with the transfer control module. I am guessing a fuse right now but really I have no idea.

I did look for wires tht got wet but found they were fine.

 

sorry, it’s the transfer case control module.

 

I have a 2008 S and I have not yet found a fuse map that matches either side of the dash. It's a bit annoying. Everything in the owner's manual appears to be IDENTICAL to the features of the model I have (other than features I don't have like the pano roof)... except the fuse maps. So I'm hoping I never need to know before I sell the car after this shelter in place is over.
As for the communication thing... it's not common, but the vehicle is old enough for electrical connections in virtually any electrical connection in the car, including edge connectors or multi-pin connectors on various control and system modules. It's damn laborious to look for connectors to unplug then reconnect, especially when this isn't a common problem... at least not in relatively dry California... other climates may speed up the degradation of friction electrical connections almost anywhere.

When you replaced the module, did you remove the battery ground cable to disconnect everything from power before replacing it? If the module was disabled by pulling a fuse, it is vaguely possible that any other module your dead one communicates with may have gone into an ignore mode that requires a "power off reboot" to reset and re-establish communications. -- DISCLAIMER = this is one of those "out there" things that seem futile, but every once in a while some odd problem is solved.

 

I had the dealer actually replace the module - I just moved the passengers seat.

The behavior has been the same for some time now - no response from the control unit and the lights on the center console for the traction control lit up (all of them). The sport button is lit up too.

I will try the fuses today.

 

If you have durametric or another good tool. Check the wheel speed sensors. Does your ABS work correctly?

 

Yes, the ABS works, and I see no issues with the speed sensors.

Why would they impact this?

 

I had some weird issues with my ABS and TC when my wheel speed sensor was damaged on my old girl. I knew it would be a long shot but at this stage it’s worth looking at the strange options too 🙂
