I'm stumped...
My airbag light has been blinking for about 2 months now, and I've attempted to bring it to the dealer, but from some reason they could not replicate my problem.

Here's what happens:
I start the car and it blinks (code 42), and then after it runs for about 5 minutes and I restart the car, it goes away. But after I had it parked for a little while, it comes back on again and I have to restart it. I tried to look up the 42 code, but it doesn't seem to be in the fault code table. Pretty sure its 42 (it goes blink blink blink blink, pause, blink blink). Does that three times and the light stays on.

Does anyone know of this problem, help will be greatly appreciated!!! (especially if I don't have to go to the dealer to pay an arm and a leg!)

Thanks

Are you sure it's not 52? From what I've seen, code 52 is the most common airbag code, and it means that a sensor isn't making a good connection. When my escort did this, one of the front crash sensors wasn't grounded properly to the frame. It's also the error code you get if a wire is broken or a sensor is unplugged, which I've seen in other people's cars.

I'm pretty sure it's 42... But when I do check its usually when its already blinking so it may be 52. If so, where is this sensor located? (if you have a pic or have a link to a pic that you can point it out to me that would be awesome!)

But is there a 42 code?

THANKS!

I had a similar problem. Don't remember any "blinking" or pulling a code (never checked). It turned out to be the airbag control located under the driver seat I believe. Possably on the passenger side.

just double check to make sure it didnt come disconnected under the seats
thats what that wiring harness is

Here's what I retrieved from my DVD:

Lamp Fault Code (LFC)

When the air bag control module detects a fault , it will cause the air bag indicator to flash a coded sequence called a LFC. The code is one digit. The digit is indicated by a number of flashes with a 0.5 second interval between pulses. There is a 5 second pause between each display of an LFC.

Each LFC is flashed five times after which the air bag indicator will remain lit for the remainder of the key in position II. If there are multiple LFCs, each LFC will flash in order of priority.

Each LFC has one or more associated DTC.
So...based on this, you have two problems, assuming I'm reading the lights correctly:

1. 4-BLINKS = Pretensioner (either passenger or driver will do this)

2. 2-BLINKS = Air bag inflator/circuit on the PASSENGER SIDE

Given this, I'm going to assume maybe something is up on your passenger side. It looks like whoever is TRAINED and CAPABLE of doing such a repair needs to look closely at thsee circuits. If you have counted the number of blinks, then I'm sure a capable dealer would be able to take this and run.

Good luck.

Sorry to resurrect an old thread, but I need some advice on the same subject.

I got in a small fender-bender and now I am getting the 4-2 airbag code. From the previous post it seems as if I need a pretensioner and to look at the passenger side circuitry (specificaly uner ther seat). Before going to the dealership I would like to know if this is something I can takle myself or if it sould be professionaly taken care of (what I'm leaning tward). I concider myself fairly proficient with tools but am worried about messing with the whole srs system.

And I know it would be purley speculative, but if anyone has dealt with this problem at the dealer it would be nice to know how much I can expect to pay.

I'm getting the 4-2 code as well, but the passenger seatbelt still extends and contracts normally. Could the pretensioner still be the problem?
