CYGNUS 2005: Steering Wheel Buttons Not Working

[Xulfiqar]

yes - otherwise airbags would also deploy when an empty car is hit also. The seatbelts are an "armed" signal to the SRS control unit. And if you put a cut up belt tongue into the clasp or even engage the orignal belt across the seatback the SRS unit assumes the driver is wearing a belt.

The belt stops you from hurtling forward and in some cars also has a reel in system (pretensioner) which go off like bombs and hold you to the seat so the airbag can save you - otherwise if you hit the steering like a raggy doll and the bag blows

"Namaz-e-Janaaza - Fateha - Pulao" - get the picture.

I hope forum members can spread the wisdom of using seat belt among the friends & family & educate them of the disaster if seat belt is not used but some PUNCH JUGGAR is used to get rid of alert beep & belt warning light on dash.

This shall be posted in a thread with subject 'safety & precaution for cars with SRS airbags'

But I know of an accident where the driver wasn't wearing a seatbelt and both, the passenger and the driver side airbags opened :S

That should be a PKDM car.

Nice info about the airbags... my car doesn't have airbags but still !

JDM Mark X :). Like i said, first hand experience.

[Xulfiqar]

the mark X also has seat occupation sensors along with sensors on the belt clasps and 2 stage airbags (meaning there are 2 squibs to fire 2 detonators in each bag, only one is fired on low impact and both fire on large impact). Most probably the car you saw had some sort of jugaarbazi done on the seat sensors or the seatbelts.

I have seen electricians put in resistors in the clasp wiring to kill the beep. In a toyota this arms the SRS unit ready for deployment. There is one circuit for both the chime and SRS unlike in nearly all european cars in which there are 2 separate circuits.

Either it was rigged or the SRS unit was faulty.

[vyrus]

Rigged it was then. Previous owner did it i think.

[vyrus]

and yes Xulfiqar bhai you're right, Both the airbags opened up even on such a small impact. So you're saying if seatbelt wasn't rigged, they wouldn't have deployed ? or ?

[Xulfiqar]

yep
