Dear forum,

I have code B2291 and airbag flashing code 17. All three of my passenger position sensors are merrily clicking away, irrespective of this flashing code. If that code light is flashing, my passenger proximity to airbag light (on the wooden part of the dash in front of the passenger) does not light if stimulated? However, if I cycle my ignition two or three (or sometimes four) times, the flashing light is extinguished and everything (including the passenger proximity to airbag light) now works and the light stays off until I next turn on the ignition? I can clear the code, but it returns.

I have checked the connections under the passenger seat and they all appear fine?

Please, what should I try next?

Thank you…

There are four sensors. Two in headliner, so manual states. Unfortunately when they are clicking it means they have power but not necessarily a signal return to the module. I have not looked in SDD to see if the signal is reported however I would expect it to be there.

Thank you for your post.
I can only find 3 sensors; on the dash, the A pillar and above the B pillar? I do not have SDD to check for any returned signal, so I am basically stumped!

Perhaps more important than an annoying dash light, will my passenger airbag still deploy if needed, please?

OldKarz,
I found the 4th sensor...Stupidly, I was not looking behind me!
That one clicking too!
Merry christmas to you and yours...

From Robert rawle south Wales UK Britain I just had the same problem on my jaguar x350 2005 4.2xjr I changed the passengers side seat sencor it's the unit under the leather on your back side seat cushion it was still the same under the seat is the earth cables under the mat lift it up you will see cables bolted to the body mine was corroded took of cleaned put back on clearded the messages on the machine worked perfectly I did not need to change the seat sensor my steering wheel is on the right side so check under your drivers side left hand drive

Thanks Robert.
I am assuming you meant to say check under my passenger seat (on the right hand side of the car)?

not sure it's on my passenger side left side I should be under your driver's side because of the body pressing try that first if not it should be on your passanger side right side I hope it will work out for you from Robert rawle

Robert, was your earth bolted behind the carpetting on the side of the transmission tunnel, or actually under the carpet beneath the seat, please?

it's under the carpet under the seat it's easier to take the seat out take the plastic long carpet holder of then lift the carpet you will see the cables that is what gerint the mechanic told me iv been friends with him for years he knows his stuff from Robert rawle

Okay Robert, thank you.
I'll take another look under there!
