Passenger Curtain Air bag problem

[Winty]

Hello

I have a reoccurring fault with my Vectra-C 56 plate Passenger Curtain Air bag. Air bag warning light keeps coming on, fault is low voltage.

Problem only occurs when it is sunny and the bodywork warms up, I can clear the fault at night after it has cooled down or first thing in the morning.

When testing during the day and bodywork is hot/warm that fault is constantly present, when the body has cooled down fault disappears and can be cleared.

I have had half the roof lining down and checked all along the air bag but I’m unable to locate the connector (am I being dumb or something )

Really would like to get to the bottom of this issue as it is becoming a pain clearing the fault code every night.

Please help

The connector is towards the back, you have a trim in your boot area which is held by one or two torx srcews and then should pull off with a little persuasion. connector will have an orange clip which pulls up about 5mm then green part will pull out..BE CAREFUL these are quite delicate

Which panel do you mean? Is it the one attached?

Ok, have got the panel off, taken the connector off and put back on, now i get a Low Resistance fault, connection sitting at 0.5-0.8ohms

Any ideas?

only thing i can suggest is when you took the connection off the bit that slides up to release the connector has a small tag at the bottom check this because when it is pushed down it breaks the circuit if you take a picture with it unconnected i should be able to tell you if it's ok as i had this problem
