Sounds like its normal for our cars. Just wish one of us can figure a way around it.

Unfortunately, similar to the previous posts, once the dash LED kicks on (30 seconds after the door locks), I cannot unlock the doors using the remote. I have an M535 immobilizer.

Thanks in advance.

Mine is the M535, so that's not it.

Whelp, there goes my theory...the mystery continues.

I have a thought. Before the system arms, the doors can be unlocked by the aftermarket remote, but the gas cap door remains locked. Do you guys know which wire triggers the gas cap door?

particlewave · 06-23-2018, 01:19 PM

Blue/green/red (blue wire, green stripe, red bands) for lock and blue/yellow/red for unlock (the same wires lock/unlock the front and rear trunk levers on models with release levers vs buttons).

I ran into some money. I’m going to start trying to replace and diagnose this issue. I found a PDF of the original diagnosis chart. Complete with values and what to test. Car gets a new top on Thursday and when it comes back I’ll dig in. I suspect one or both of the lock mechanisms has failed. The diagnostic chart thankfully tells you how to tell. They’re 350-400 bucks.

None of the key resyncing procedures I've tried have worked...and I've tried all of them.

I called ECU Drs yesterday. I’m going to send it off to them. They’re going to verify it’s functioing properly, and program an extra key for me. As soon as it gets back from having the new top installed I’ll send the CLU and ECU to them.

Swhitcomb · 09-07-2018, 05:52 AM

Ordered new door locks yesterday and sending the CLU and ECU to ECU drs this weekend. Wish me luck.

Swhitcomb · 09-11-2018, 02:16 PM

Passenger door lock is in. No change. Will report back after I replace the drivers side. None of the activations in durametric work still. About to box up the immobilizer and send it out.

Swhitcomb · 09-13-2018, 07:31 AM

Ive owned this car since December of 2013. I finally get the time, money, and things sorted to send the CLU and ECU to ECUDoctors, ship it off yesterday (from VA to FL) and of course, there’s a hurricane. Shipping pretty much shut down. Box is sitting in Laurel MD and will be there who knows how long. I just want to know what’s wrong with the car. I’ve waited long enough.

I know, trivial for those that are in the path of the hurricane, but I’m being selfish for a min.

Oh, that sucks...

Swhitcomb · 09-18-2018, 02:14 PM

Well, they got it today. Got an email around 1130 that they were looking at it. Never heard from them and they close at 4. I’m really curious to find out what’s wrong with it. I’m also having them reprogram the original key and sell me an additional remote.

Swhitcomb · 09-21-2018, 10:14 AM

ECU doctors is done and it’s on the way back. They replaced the immobilizer. As I knew, it had water damage. They were able to get a new key to work with the old unit, but the codes it was throwing they believe are because of the water damage. They programmed and new key for me while they had it. It should be there on Tuesday. Hopefully the issues will all be solved.

particlewave · 09-26-2018, 02:48 PM

Did they give any clues about what the actual issue was?
Unlikely, but would be nice to know.

Swhitcomb · 09-27-2018, 02:29 AM

They didn’t offer any insight. However, the new immobilizer is brand new. It works perfectly with the Porsche key, it does the exact same thing it was doing before with the 3rd party key. So my theory is that perhaps this particular model of M535 isn’t compatible with it for some reason. There are 2-3 M535s. They actually were able to get the old immobilizer to work fine, they just wouldn’t warranty it due to the water damage. Nevertheless, I now have a functioning key, and valet key.

Hi Guys, I have read this whole thread twice but cant get my door locks to work. I have a 2003 base, I also have the M535 unit. I have the tail lights successfully working when I hit the lock/unlock on the remote but thats it. I found the brown/white wire for sure but there seems to be two brown/red wires? Is the wiring different for the 2003?

thanks in advance,

Dave

The wiring for this is the same across all 986 model years.
There should only be one brown/red wire.
There is a brown/red/black wire (brown wire, red stripe, black bands), so make sure you didn't get them mixed up.
