Technical Passenger air squib fault

[presley6]

Hey everyone I have a 2002 fiat punto and I have had my air bag light on for some time now. A Diagnostic test showed it was the passenger airbag squib. I have seen some information on this site about removing the connecter to clean it. I just need to know if

1. It's safe to do so or is there anything I need to do to make it safe

2. How do I get to it

I have attached a picture of what it looks like to me can add more if it's not good enough

Any help I would be so grateful it's driven me mad

You're supposed to disconnect the battery before you touch it. I've never bothered but then again I've seen whole sets of airbags set off accidentally so it may be best! Airbag connectors usually just wiggle straight out, give the pins inside the airbag a tiny tweak to one side, that usually does the job.

Thank you. Will give it ago tomorrow. I have also just noticed there is another yellow connecter to the left of this one will I need to disconnect that too?

What did the diagnostic test actually say? Open circuit? High resistance? Simply removing the plug and cleaning the connections is extremely unlikely to solve anything

You should disconnect the car battery for a minimum of an hour before you start pulling airbags or wiring about as capacitors can still have power which can fire the airbags causing serious injury

I beg to differ. 99% of electrical faults are caused by poor connections and airbag connectors are notorious, it only takes a slight increase in resistance to put the warning light on. I had exactly the same fault on my Multipla, a quick tweak of the contacts was all that was needed.

i had a customers car with the Passenger Air bag squib Value too high and Open circuit

I check the wires from the ECU to the connection - fine
Checked wires from the Connection to the airbag mini connection - thats fine

since i couldnt find any issues - i stuck it all back together - and reset - hey presto cured

he hasn't had it back on in a while

So was there a fault - sod off was there - just once an ecu gets un happy - you have to fool them sometimes to make it think its okay again

So a full discharge - a full check as i can go - reassemble - connect battery and wait - ignition on no issues

The test came back as passenger side airbag squib no codes

I recently had it reset and the light went out but came back a week later.

I can't gain access to the plug it seems to be mounted to the side my hands are to big to fit through the gap can the the metal frame be unscrewd?

Your reader is not able to read correctly
the fact its given HALF the problem, means its pointing but not fully in right direction

The other half of the code SHOULD BE
open circuit
High resistance
Value too high
Value to low etc etc etc

Right
STOP

Disconnect the battery - leave it off for 10mins, to allow the car to discharge and for the airbags to also discharge

While its discharging, empty your glovebox
There are 2x Small springs in the bottom corners for hinges
These simply need pushing towards each other (ie left hinge goes right - right hinge goes left)
The glovebox will drop

Then attack the 4x 10mm bolts undoing the tension at first on all
Then remove

But make sure your 10mins is up before removal

Pull airbag out - disconnect wiring plug

Refitting is reverse
Except ensure all connection are okay and clean and tight
Reconnect battery - wait 1 min
Put ignition on - let car complete self test
