SRS control module is mounted on the side of transmission tunnel just in front of the shifter.

Most likely wire from SRS to A1e15 was severed deliberately to hide existing problem.

Wiring diagram you have attached is for newer vehicle.

Thanks, sorry for mixing up diagrams. It apparently is a 2001 according to the VIN. Sounds like someone creative worked on the car earlier eh?

 

Could you possibly have a 2000 ML? Post your full vin #.

Check fuse #10 in eng. compartment fuse/relay box. Also check to see that all the other components for fuse 10 are working.

 

The VIN is WDC1631541X705666. Looks like that makes it a 2001 model? I guess the I cant read, the docs are wrong or some combination .
Ill check out fuse #10 and the respective components, thanks!

 

Based on the VIN and data card, it was built in the Graz plant, Sept. 28, 1999. That would make it a MY2000 car.

 

@43sqd: The VIN's 10th digit only indicates the model year on USA VINs. For other countries, they are not required to designate a "model year". Instead, they have often use "plate year" which is the first year of registration, and is not always correlated even to date of manufacture.

@Witek: The "809" code just means "year of manufacture", which isn't the same as USA model year. For exampl, my MY2007 CLK had code 806, as it was built in 2006 as a MY2007. Same for my MY2011 SL - it has code 800 (and there were no MY2010 SL's - they skipped it for some reason).

The best thing to do is refer to the WIS documents according to manufacture date.

 

Question to OP. Let's say we figure out why SRS and Airbag_Off lights do not work.

Looking at codes problem is with right seat occupation sensor/child seat recognition. Are you willing to fix it? Is it still available?

 

Yeah, my intention is to fix the underlying issue. Ive only checked for frayed/damaged wires under the seat so far, looks like there is still a sensor there and no apparent damage. I figured that the short of the light should be fixed first so I can get some feedback when tackling the underlying problem.

After the help Ive gotten so far, the plan for the coming days is to use diagrams for a -99 car and see if someone messed with any cables from the airbag module.

 

Hello everyone,I hope you're all well.

I have some silmilar problem with my ml430 1999 airbag system.Maybe someone can help me!!

It has been a little while the SRS light is on the dashboard.AIRBAG OFF light is off.

When I turn on the car the lights are both on, after 4 seconds AIRBAG OFF light goes off.

It has been diagnosed a faulty child mat sensor by a mechanic the first time.

I've bought an emulator from Poland, which didn't seem working as the light was still on even after I took the car back to the mechanic to erase the fault code.

I removed the seat mat from the seat and replace it with a used one which I bought from a car wrecker.
Did not work as the car was a 2001 mine is 1999 model.

Then after a little time I have decided to give it another try and I bought an other emulator, this time from England.Obviously even this one didn't work.
When I plugged it in also the AIRBAG OFF light came on, then both lights go off for less than a minute and alternatively on and off just like a cycle.

In the meanwhile I got few more diagnose with the result of the following codes: B1153-- B1152--
I bought a diagnostic tool (icarsoft pro) which gave me the code: B1524 airbag ignition circuit driver

Is it possible that the last emulator I installed it works okay but there is another problem in the circuit?
Does anyone know exactly what code is B1524?
Could be the clock spring?

Thank you guys!!!!
