Welcome to NPOC

Most common reason is the Driver Side Seat Airbag
Unplug and replug the connector a few times under the Seat. They often get kicked or move when different Drivers adjust the Seat.
Next most common is Passenger Front behind the Glovebox. Same process.

Then try a reset

If there is still an error, it will flash in a sequence that can be looked up in the Service Manual.

As your airbag warning light bulb probably has died, it's is a bit complicated to follow the instructions so you'll need to count the seconds provided in the instructions.

The instructions imckay is linking to needs some comments. Here is my modified version:

0 If diesel engine, let the engine run until it's warm. If you do this on cold engine, in particular in wintertime, your battery, nor your glow plugs/relay will not be happy.

0.1 while you have the ignition on, pay attention to how the airbag light is flashing. If each flash and/or time between flashes is of equal length, your system is in fault mode. If so, keep going with all steps of this insrtuctions (you may skip step 6-7 if you want to). If at least every 15th pause between flashes has double duration of the others, you system is in diagnostics mode and you should jump to step 6 (or 8)

0.2 Make sure your ignition has been off for at least 10 minutes (but not so long that the engine gets cold)

1. Turn ignition from off to on.

2. The airbag warning light will stay on for 7 seconds, as soon as it goes off (within 1 sec) turn off ignition.

3. Wait for more than 3 secs. But NOT MORE THAN 5 SECONDS.

4. Repeat steps 1- 3 two more times.

5. Turn ignition on again. If you've done this correctly, the airbag warning light should flash with a different pattern than what you saw in step 0.1. This means your airbag system now is in diagnostics mode. If the flash pattern did not change (look through at least 15 flashes before you make up your mind), you failed in the process. Then leave the ignition off for at least 10 minutes, and start over from step 1.

6. (Optional) Now the airbag light will flash in a pattern. Count the long and short flashes. The pattern is repeated. Each time it starts over, the light will be off twice as long as between the flashes during the pattern.

7. (Optional) Lookup the airbag diagnostics in the factory service manual (can be downloaded from this forum). There you'll find what the pattern is telling you. Usually it is a loose cable connector under drivers seat or passanger seat. This connector is near the handle you use to adjust the seat forward/backward. And easily messed up by people reaching for the seat adjustment handle. (I've never heard of this problem in cars with power seats)

8. Turn ignition off for at least 5 seconds. Correct the problem. Usually, just press the connector under the front seats tight.

9. Redo steps 1-4 (or steps 0-4 if your engine got cold while you were decoding the pattern). This should reset the system and bring you back to normal mode.

10. Turn the ignition on. After 7 seconds the airbag light should go out, and stay off. If it still flashes, look for pattern. If the flashes are uniform, you did the process correctly, but didn't solve the problem, or there were more problems and you solved only one of them). If the flashes are not uniform, you failed in step 9. If so, let the ignition be off for at least 10 minutes and redo step 9.

In short, the process is:

Warm engine up, ignition off for at least 10 minutes.

ignition on for 7-8 secoond, ignition off for 3-5 seconds, ignition on for 7-8 secoond, ignition off for 3-5 seconds, ignition on for 7-8 secoond, ignition off for 3-5 seconds, ignition on

watch for pattern that confirmed you've done it right so far and optionally decode the flashes to identify the error code.

ignition off for at least 5 seconds, ignition on for 7-8 secoond, ignition off for 3-5 seconds, ignition on for 7-8 secoond, ignition off for 3-5 seconds, ignition on for 7-8 secoond, ignition off for 3-5 seconds, ignition on

error should be gone

Hi, just re-joined. No joy on old login. 2002 Primera P12 1.8 Petrol Estate. Am presently getting this back for on the road. Have owned it since 2009. Also have a Mitsubishi Colt 5 door 1.3 08 and a Renault Grand Modus 1.5 diesel 08. 

Continual flashing of airbag light after illuminating static for just a few seconds. Checked under seat connectors. Checked connectors into Airbag unit (remove centre plastic console to see it). Finally did this:

Turn on ignition. Airbag light comes on static. But as SOON as it starts flashing (you've got to be quick) turn OFF the ignition. Repeat a further FOUR times.  In my case this worked just like magic (well I first bought this car in 2009 to carry gear to do my magic shows - but I don't thing being a magician is related to the success of the re-set - ha-ha). Looking forward to the old girl being back on the road. Last used September 2020 when we managed a few days in Lytham St. Annes and boy, did it shift up that Motorway! Just got to try and get more performance out of the handbrake prior to MOT. Renault is £30 road tax and 60 mpg so will retire Mitsubishi for a while now.

Guess you miss counted. It must be repeated FIVE times for a total of SIX. The first 3 puts it into diagnostics mode, in which it will tell tell you where the fault is (by its flashing pattern), and the next 3 will perform the actual reset. As described in the post before yours.
