Equinox 2007 I repaired under seat and cleaned for my Chevrolet Equinox , after that it shown passenger air bag OFF but seat belt is alert its Ok ..

spontaneously alerts ??? Warning chimes Warning Devices The warning device system consists of the following:

• Key-in-ignition warning switch
• Door ajar switch
• Driver and passenger safety belt minder switch (integral to the safety belt buckle)
• Vehicle security module

The instrument cluster and the restraints control module (RCM) control the following chimes:

• Safety belt warning (repetitive chime)
• Key-in-ignition warning (repetitive chime)
• Headlamps on warning (repetitive chime)
• Door ajar warning (single tone)
• Air bag warning (repetitive chime) The following 5 distinct chime rates are used to indicate warning:
  
  • safety belt warning is 1 chime per second
  • key-in-ignition warning is 2 chimes per second
  • headlamps on warning is 4 chimes per second
  • door ajar warning is a single chime
  • air bag warning is 5 chimes per second
  • now which of these is your vehicle doing ?

I finally got out my ohm meter and the circuit diagram and checked out all the wires. Turns out the problem was an open circuit in the drivers side seat heating pad. The connectors are fairly accessible under the seats. The circuit is rather involved since the control module is under the passenger seat and the inputs come from the switches on the dash through the climate control module!! What a complicated execution for heated seats!
But I was able to find some new replacement seats on Craigslist and picked one up for $100. It was pretty easy to replace with just the 2 bolts at the back, the wiring harness underneath and the shoulder belt clip. Now everything is working and I sold the old seat for $60. A ne $40 repair and 3 hours of diagnosis and swap work.

air bag light on posible causes
car been in accident and air bags activated and replaced without resetting air bag modual.
bad conection or broken wire under front seats theres conectors for seat belt tensioners all linked to air bag warning light have a look under your drivers and passengers seat make sure they aint pulled when the seats moved back n forth

Here's a quick check list for most common cost of SRS / Air bag problem.


Dirty contacts on driver and passenger seat belt buckles

Dirty contacts on seat belt connectors (under seats)

Dirty contacts on driver and passenger sides weight sensors (under seat)

Seat covers

Weight on passenger seat

(Example: grocery package trigger SRS / Air Bag light on the way home.)

I recommend you to pass an vacuum over the contacts and use CRC electronic parts cleaner to rule out connectivity problem.

I DO NOT disconnecting the negative battery connector to clean the code(s)

Without the code(s) the dealer will takes "BILLABLE" time to reproduce the problem.

Working on the SRS is very hazardous and therefore is not a DIY repair. Take the car to a professional for diagnosis and repair of the SRS.

The airbag will not be active until enough weight is in the seat, I believe it is somewhere around 70 pounds. Try having someone sit in the seat and see if the airbag is turned on. Let me know if this helps and please rate this solution.  lone99star

HIYA!
All Equinoxes has yellow coloured wire harness to identify this as a air-bag system.
This yellow coloured wire 'system network' has connections in some areas...one is located at the front passenger's floor area close to the door (right-side corner area, just remove screw or clip and plastic trim part to gain access to see yellow wire there-it has socket plug connected with red clip-string to secure it) and another yellow wire is found between the front seats-you need to remove armrest, center console area and possible remove the front passenger seat to see yellow wire connect to black device underneath carpet in the middle.
Check to ensure the yellow wire sockets are plugged in properly, and not accidently cut or pulled off during your underseat repair.
In case your Equinox has roof side air-bag option, the yellow wire/sensor are located below the front seatbelt device inside the lower pillar frame area. (it's between the doors)
Hope this help you solve your repair task.
