“Thank you worked like a charm!!!! I have a foxwell, getting error codes 31 ignition circuit - side airbag , driver
and 21 ignition circuit, driver
no idea what to do. Horn works depending on its mood. “
Any suggestions would help. I’ve taken off the door panels and disconnected and reconnected the airbags.
Hello everyone! I’ve run into some electrical problems on my '08 Turbo and I’m stumped.... I've looked through a lot of Renntech posts and don't see any thing close.
First the panoramic roof and sunshade were opening and stopped about foot open. Maybe coincidence, it happened right when someone opened the door. I’ve checked practically every fuse even pulling the pano-roof control unit (back where the motors are located, and the circuit board looks okay. Then the instrument panel has started to act strange. The gear indicator shows that it is all gears at once, see the photo which is while it is in drive and moving. I can shut the car down and restart and the problem goes away. The time keeps changing randomly and the outside temperature is wrong. The button that opens the rear hatch that’s on the driver door has stopped working. Then my battery died, it was five years old so no surprise. After I replaced it the airbag indicator on the panel has lit up. I’ve tried to reset the instrument panel (Main Menu> Settings > Factory Reset) but it will not allow me to select “Reset”. I’ve also pulled the fuse several times to reset the panel but no change.
Today, I’ve connected my iCarSoft POR II diagnostic tool to the car.
The Airbag section says it “cannot connect to the ECU” so I can not reset the airbag light. There are YouTube videos of people using the tool on Cayenne’s (albeit on newer models) to reset it so I believe I can. The Panoramic roof says it does not have any DTC codes. The lift gate button on the driver door indicates it has appropriate voltage and no DTC codes. Also, no DTC codes for instrument panel, electrical system or DME I’m not sure this is related or not, I changed out the interior incandescent bulbs with LEDs. I now know that LED bulbs give off electromagnetic interference but seems remote. (as a side note, I found this out when I put LED bulbs on my garage door opener unit and it stopped receiving commands from the remotes – I had to get special bulbs from Amazon) Yesterday, I removed all the LEDs and went back to the old bulbs – no change.
Any ideas, suggestions or guesses?
FYI: The car is in Drive, "D" and is in motion.
So only managed to see a black square of tape expertly placed over the Airbag light (ON all the time), only because of driving it in the sun with the top down. Been concentrating on other parts of the car.
Any-who, that has lead to seeing that the Seatbelt light doesn't appear at all, and closely related, the horn didn't have a fuse in it at all.
So this has brought up a question, the Codes reported, the electrical drawings (Bentley), ....while they say "passenger" or "driver" side, does this in fact relate to the left and right side of the car when it is the probably more common "left-hand drive"?
Code 30 Ignition Circuit, side airbag passenger................is that actually the right side?
This will not reset with the Durametric. I looked at the airbag connector in the left door, but now I am thinking it may actually relate to the other side of the car, i.e. LHD passenger
Interestingly, the Airbag module wiring, Passenger Side Belt Lock, that wire is cut at the plug and a grafted in wire (plug connected) heads off under the dash somewhere (yet to be traced).
So that Br/Bl wire say passenger, but maybe it relates to the right hand side of the car, in this case the drivers seat.
BTW, the left seat, (passenger), does not have a wire at the buckle, but I think maybe the RHD ROW, or Australian RHD cars didn't have that anyway. Or has been replaced with the wrong buckle.
So maybe the Airbag light was covered to avoid looking for a fault, might be a plug.
Could it be related to the seat-belt buckle, again patched to avoid fixing it properly? The light doesn't even go with the self-test, so could be a bulb.
I have read that the seat belt buckle may not be included in the Airbag ignition circuit for this region.
Horn didn't have a fuse in it. Relay operates with the horn pad, but no horns, so maybe bad horns.
The fuse may also have been removed if it had that bad horn pad issue and going off on its own.
I had to disconnect the passenger side door airbag as part of door panel removal, to replace the door lock mechanism. To check that I replaced the part correctly, I reconnected the battery and turned the ignition key, and got an "Airbag Failure" warning. The fault didn't clear even after disconnecting the battery, reconnecting the airbag and closing up the door panel, and reconnecting the battery. I confirmed the airbag was reconnected. I suspect that it may be a "latched' fault that can only be cleared via the Durametric tool - thoughts?
