Hi all, It seems there are some cases going around regarding 996's airbag warning lights and all possible causes. I thought I'd share my story in a new post, since I could not find a similar thread to post this on to as a reply. My car is a 996 Carrera 2 (model year 2000, EU model). My episode started during other maintenance work. I had left the key in the ignition while I had a battery booster on (Note: do not leave the key in the ignition when using a booster!). Apparently this caused a voltage spike, which broke my airbag control module (part # 996-618-219-00). After having my car hooked up to a PIWIS 2, I got the following fault codes: 3, voltage 195, control module internal fault 46, belt buckle driver 49, belt buckle passenger 23, belt tensioner driver 25, belt tensioner passenger 64, seat occupancy detection passenger 72 child seat detection I ended up ordering a pre-owned control module from a 2004 Boxster S (part # 996-618-219-02), as the parts were interchangeable between Boxster and Carrera according to a local specialist. (Note that there are two separate part numbers, depending on whether you have side airbags or not.) After swapping in the pre-owned module, I still got the following fault codes: 53, side airbag sensor, driver 56, side airbag sensor, passenger It turns out that both of the sidebag sensors (part # 996-618-221-00) had also perished due to the voltage spike. After swapping the original modules for a pair of pre-owned sidebag sensors (part # 996-618-221-01, again Boxster parts), my local mechanic was finally able to clear all fault codes. Note that the warning light will not go away by itself even after the problem has been resolved, you’ll have to clear the fault codes with a diagnostics tool first. I’ve read from elsewhere that a new control module needs to be locked in to the car, and that once the module is locked it cannot be unlocked. While the module indeed cannot be be unlocked, in my experience it is still possible to swap the module from another car. -
Hello! year 2006 model 997.1 I feel like I bumped something, enabled something. This is a warning only, does not appear to have any other effect. It goes off after a few seconds. It does it every time the car moves from from a lower speed through 29 mph. See video here https://share.icloud.com/photos/0e1kVKRRnx-W7xJcaR56hIyrw What is this? How to disable? Thank you. -Sjo

Hi everyone, I've had a spoiler warning lamp on since I bought my 1998 996 convertible a few years ago. As an electronics engineer, I decided I may be able to tackle this issue myself. Before starting, I have read numerous previous posts regarding this issue, and what the fixed-wing bypass harness (996 612 070 51) does. When the rear spoiler is elevated, I'm getting zero Ohms between the Grey/Brown (A2) wire and the Brown (A5) wire, as expected. This becomes open circuit when the lid is lowered. There is then zero Ohms between the Brown (A5) and the Green/Grey (A4) wires, again as expected! The switching of the brake lights works normally too, but still the warning light persists. I am wondering if there could be a corroded plug/socket further forward from the rear of the car because the one at the back is very clean and the microswitch states are normal in both positions. I'm not sure if this is a common fault, but I'm guessing it probably isn't as I can't find anything online. One thing I have noticed is that although the manual up/down wing rocker switch works, I have to keep is pressed down until the wing is down. When I try to elevate the wing manually, the switch triggers the latching function of the relays, but when the spoiler is fully up, I can still hear the motor continuing to turn and the gears slipping inside the rear mechanism. The gears will eventually strip and I'll end up with a bigger problem, so any thought on this nuance would be greatly appreciated. Many thanks, Dave
