Airbag Fault codes DF253 - DF252

[greg.m]

Hi guys!

I have a clio sport 2003 model and I run some diagnostics because I have the serv and airbag lights on. The two faults I got are DF252 and DF253.
Here are some pics:





Does anyone know what is this exactly and if its easy to fix it?

I haven't change my car-battery since 2008, could it be the battery that's causing these faults?

Seems to me that both rear seat belts are faulty or not plugged in.
has the car had any accidents?.

I'm on the page that lemonnobby1 is heading to. Sounds like crash context data has been removed (which resets the module to default) and now it's looking for equipment that isn't installed.

Of course it could be a wiring issue to

All 172 have rear pretensioners expect cups. i surpose you could disconnect and reconfigure

Guys, thanks for replies!

I found this from "Little old me" a guy from another forum:

"OK DF253 is the rear seatbelt pre-tensioner has deployed, put a 3 Ohm resistor on it and the fault is gone."

But the truth also is that i bought an used ecu from exactly the same model as mine because mine was - i dont know why - broken. I never had a crash but maybe the one i bought had one. I have to ask the guy i bought it.

I had one that had gone dead just this week. Id just unplug them and reconfigure.

Is there any guide on how to reach them or how to do it? Maybe some pics?
Im a real noob with all of these...but im trying to learn a little bit now.
I got crazy when i went to official Renault here in Stockholm and they asked me 600£ just to change the airbag ecu and 220£ to change ONE xenon barb!!!
After that i decided to give it a try by myself! Until now it has cost me around 130£ - diagnostic tool with software and a used but working airbag ecu!

Hmm I seem to have this issue on my 182 pop up this eve, been fine no issue for a few week's got in it today and airbag / serv light on, run renault clip and identical codes as per begining of this thread.

What and were do I install the 3 Ohm resistor? Anyone got some pic's

Cheers

Haven't got any pics to hand but along each rear 1/4 will be a pair of wires, one blue and one brown from memory with a white plug on that clips into the rear belt inertia mechanism. Resistor need to go into the white plug across the two wires

You'll need to remove some of the plastic trims in the boot and follow the rear belt, once you see the mechanism reel it's pretty obvious
