Question about 2002 Honda Accord
Need your help for the first step here. The question was posted twice as a "I have the same problem", so there may be more than one request.
Error/Fault codes need to be extracted to get an idea where the problem is. If you could help with that, I can take it from there (If need be). Most shops just go for replacing the brain and hope for the best on the sensors. If the brain isn't holding its firing charge, then replacement is necessary. But I always try to save the Asker money. Soooooo,
Anyway, my response (so far):
Thank you for the compliments, I will do my best to live up to them. I like to provide as much info as possible on so serious a subject. So please be patient with the overwhelm.
My main experience in handling Airbags was the extraction of them at a wrecking yard for resale. Specifically the safe handling of undeployed airbags AFTER a crash. In the 15 months I was at this location, I pulled well over three hundred of them with zero accidental deployments.
Click here for precautions to take when handling, working with on or near airbag systems. I supply these as a cautionary bit of advice for anyone who might be working near these systems.
The problem you are describing is a coming from what is commonly referred to as the DERM (Diagnostic/Energy Reserve Module). To be honest, I'm not sure what Honda calls their version of the DERM. For lack of a better term, call it the Brain Module.
The brain makes sure your system is in working order, receives sensor info and holds a charge that deploys the airbags even if the battery gets destroyed in a crash. That charge why even a car without a battery can still deploy an airbag by surprise.
Every time you start your vehicle, this module performs system diagnostics (indicated when your SRS light blinks). After a successful diagnostic, the SRS light goes out. When it stays on, that means there is a fault.
Now here is the area I'm weak in. The fault the brain module found is held in storage. As you may imagine, running diagnostics on wrecked vehicles wasn't a top priority. As such, I can't advise you on the next step you need to take, which is how to retrieve these codes. They will indicate the type of fault and where it is in the system.
I'm not sure if your Honda has an ODBII diagnostic option or if system error codes are retrieved via another route. For this, I would have to refer you back to Toyota Ed.
I can tell you that in 2004, the price of individual airbags was usually over $500.00. Airbag sets and the brain from a single vehicle was over $1,000.00
While the dealership can definitely fix it, the cost could approach $1,000.00. We, here at FixYa consider that to be a solution of the last resort.
So, I hope this helps, but I must hand this problem back to Toyota Ed temporarily in order to get those codes.
I'll be waiting when they are retreived.
Hello. That was very good input to the Client. Regarding the "Brain", or, more commonly known as the Center Air Bag Sensor, it does hold a charge for 90 seconds in the event of a castrophic battery failure due to impact. It would be rare that the CABS would blow a bag just being installed, as the front sensors and the G (or decel) sensor all have to have a "handshake" to blow the bag(s).
The G sensor only activates if the inertia switch sees a 35 and above immediate decel to zero. Sort of like hitting a D-9 blade.
A "right-now" stop. Let me know if you need more info.
