So, today I finally got my 968 back from the WP/Belts service after two weeks. All seals, belts, cam chain tensioner pads, etc.
Much quieter now, and doesn't spray coolant everywhere.
$3850.

They notes an air bag fault code 23 which, according to the tech bulletin they printed out, is for "ignition pill circuit 3 - resistance too low/high
But my service guy was unable to determine what what it meant or what was causing it.


Does anyone have any information fault code 23?
Could this be the reading my center "!" light in lit in the gauge cluster?

One of the airbags in the dash on the passenger side is more than likely bad. Could be a bad connection or wiring problen to the airbag too

If your airbag light is on then your center ! will be on.

If it were mine then I would try clearing the fault and see if the light comes back on.

If it does then I would unhook the battery, wait about 30 minutes, unplug the passenger airbag and put a 3.3 ohm resistor across the plug. Hook the battery up, turn the ignition on and clear the code and see if the light comes back on. If it does then I would repeat for the drivers side.

If this does not work then I would try to test the sensors or plug in a good used airbag control unit and see what happens.

Well that sounds expensive.


The air bag light does not come on at all. Not when starting, and not with key in any other position.

Make sure the airbag dash bulb is good, it should come on when you turn the key to the start position.

+1 There should have also been a code for the warning light not working in the computer if it is not illuminating

It does not come on.

You need to pull the instrument cluster and check the bulb.
