Xantia side airbag warning light

Post by Xant_II »

I have a problem with my side-airbag warning light on a ’99 2.0i Exclusive. It's been intermittent for some time but lately more persistent. I get error code 06 with the Sykes ACR4 reader indicating ‘warning light malfunction’ on RH side-airbag. Tried all sorts: under-seat connectors, substituting airbag with appropriate low ohm resistor, even tried alternative good secondhand main airbag ECU module, all to no avail. Just wondered if anyone had any thoughts on this or maybe could point me towards the wiring diagram for the Autoliv 550 74 09 00 system on the Xantia. Suspect it must be a wiring fault but where? Many thanks in advance, Charles

Pop your VIN up - there are a lot of different diagrams according to options including multiple airbag combos, so need to get the correct one for you.

On a Xantia I had the side impact ECU (L/H) had failed. Replacing it cleared the fault. I am NOT saying this was the same problem as yours, but it is something to be aware of.

Thanks guys, VIN is VF7**************[VIN obfuscated, can be read by forum staff] - it's a Sept '99 2.0i Exclusive Auto Estate - I think it just has the two front airbags, plus side airbags in the front seats.
re. ECU, presumably it is is just the main centre ECU module below the centre console?

There are also side airbag ECU/trigger units, one inside each 'B' pillar, they are accessed after removing the front seat belt reel.

Here's the Airbag Circuit for your Xantia with your specific options / fittings.

Most Equipment Codes can be found in numerical order on our Wiki here:

Good news problem solved - it was indeed the RH side-airbag trigger module - managed to pick up a good second hand unit from a 2001 model Xantia. Tempted to look inside my faulty original unit, see if anything looks wrong, my suspicion is a dry joint maybe? Thanks again for all assistance with this.

That 2001 model Xantia wasn't an Activa by any chance was it?
