Hi guys,i got a question. Is steering wheel airbag in ML55 is the same as in any other W163 or different? I installed it from Ml500 but looks like it got bigger space between steering wheel. Maybe it didn't go in right but screws went it pretty good.
And would Airbag module from 2002 ML500 would work on 2001 Ml55? Ml55 doesn't have A pillars airbags , 02 does have them.
Car was in the accident, trying to see if parts will work from Ml500 to Ml55 Thanks

Maj. Dundee

Yes they are the same part numbers. You didn't do something right.

IgorE350

Thats what i thought. What about that Module, Do you think it will work from 2002 to 2001 even tho it have 2 less airbags?
Thank you

Maj. Dundee

Modules are vin# specific, so you will not be able to use it. But if you were in an accident, and the driver's air bag deployed, the Air Bag Module is programmed to log 3 deployments. So just install the new air bag and clear the codes in the Air Bag Module.

If you were wearing your seat belt during the accident, then you might have additional problems with the seat belts.,

Got the car at the auction that was in a accident. Driver side and pass side airbags needed to be replaced and seat belt as well. So i got 2 airbags, seat belt and module from ML500, installed it in to the ML55. The light is on but i didnt try to clear it out yet. So you saying that the Module wont work?
Thank you Mr dundee

Maj. Dundee

Clear the "B" codes in the Air Bag Control module and see what happens.

IgorE350

On the original one or the replacement from 02 ml500?

Maj. Dundee

Igor, you cannot use another module in the existing veh. you are referring to. So if you replaced a driver's air bag, you clear the codes in the module of that veh.

Hi, ok today was a nice warm, sunny day in Cleveland and i got a chance to work on my project car.
steering airbag not fitting right. Took it off inspect everything real good, found a problem! The horn bracket, or whatever you call it, the metal that is on 3 springs was bent from airbag blowing up. Got that

As you recommended, i installed the old airbag module, thank God i didnt trow it out. Scanned the system, got a code B1869 for the ignition circuit with component R12/11 (left rear side airbag ignition squib) is faulty
So i guess i need to replace Left rear airbag? I do have one from my parts car.
Thank you for your help and thank you that you told me to put original Module back.

Maj. Dundee

But did the left rear side bag deploy?

IgorE350

No, just front 2 and seat belt needed to be replaced. i wonder why rear door airbag is faulty. maybe just a connection?! ill check in next few days when i have some time to work on it.

IgorE350

Replaced that rear left door airbag, looks like its all good. it gives me right rear seat belt error now, but i have the right rear seat out i am reupholstering it right now, so ill find out for sure when i will install the seat back up, but i think it worked out pretty good.

IgorE350

Ones again Thank you soooo much for your help!!!! Put the seat back in, started the car, No SRS lights Thank you soo much!!
I have another problem, Car overheating and auxiliary fan doesn't turn on, i will post a question later, if you could help me that would be awesome.

Maj. Dundee

It doesn't ever turn on, with or without AC?

Check the 100amp fuse at the battery.

IgorE350

Its a 01 ML55 was in a accident i replaced radiator,auxiliary fan and thermostat.
First sigh was i could not fill up the refrigerant to the ac system, when i turn on the fan and ac on, the auxiliary fan turns on with ac compressor for id say 10 to 20 sec and then shuts off.
fuse 44 is fine and relay is good, new thermostat installed. Auxiliary fan is good, because i hooked up another one i have and it does the same thing.
I will check the fuse on the battery tomorrow.
On Auxiliary fan there is positive,ground and white and blue wires. I assume that one of them is ac control and one of them is coolant control. where do them 2 wires go to??? maybe i can check for continuity??? maybe wire is broken some place? or do you have any other suggestions??? Thank you

Maj. Dundee

First of all, why didn't you tell us in your original post that the ML was in a front end accident?

Secondly, you do not have an auxiliary fan, you have one large suction fan and fuse #44 does not apply to your truck.

Thirdly, if you have four wires RED, BRN, WHITE & BLUE, that applies to a 2002+ ML55, please post your vin#.

RED wire is from the fuse on the battery
BROWN is ground.
WHITE is signal from ECU
BLUE is from fuse #22

IgorE350

Sorry, i didn't mentioned that car was in a front end accident, i thought i did. Yes, I didn't know it was called Suction fan, i seen #44 said fan so i assumed it was it, but now i see its #22 and i checked with multi-meter from plug blue wire to fuse 22 its all good as well as relay K26 is good.
My car is 2001 55 and it does have big Suction Fan vin# is 4JGAB74E71A229618
I think fuse on the Battery is good because fan wouldn't turn on on AC at all right?
Why do you think i cant charge refrigerant and the fan doesn't turn on when it gets to the certain temperature? Maybe temperature sensor is bad? but Gage show good on the cluster. what else should i look for? please help

Maj. Dundee

Igor, you are thinking about the wrong concerns. Your main concern should be getting a used or new fan because you are over heating. If you continue to drive the truck, your engine and transmission are at risk.

IgorE350

I am not driving the car, got it last year, and trying to restore it. Fixed the damage from the accident, doing new custom interior, new rims,tires New BMW Imperial blue color. But these 2 things are left, fill up the ac system with refrigerant and get Fan to kick in when it needs to kick in.

What i am saying is, it cant be bad fan, because i have 2 of them, have one from another ML500 that i hooked up and its doing same thing, turns on when i turn blower up and press ac button, for about 10 seconds and then shuts off. Can it be that i have 2 fans that are bad? so how come it works on AC???
Is there a way to check the Fan itself?
I am thinking something doesn't let the fan know to turn on when it gets to the temperature that it need to turn on.

IgorE350

Mr Dundee, do you happen to know what plug and what pin is the other side of that white wire?? i cant get continuity to white wires i tried on ECU Maybe that is my problem? Fan doesn't get signal from ECU. Thanks
BUt i still dont get it, how come AC turns on the fan?!

Maj. Dundee

Do you have 3 wires or 4 wires at the fan connector?

IgorE350

2 thick wires RED and Black and a little plug with 2 wires Blue and White Blue going to fuse 22 and white i cant find where is the other end of it to check for continuity.

Maj. Dundee

The WHITE wire from the fan conn. goes to the ECM, conn. A, wire #6. But it changes color at the ECM to Brn/White.

IgorE350

Just checked that #6 to the white on suction continuity is good. I dont know what to do now. should i replace coolant temperature sensor or ac sensor? what can cause that?? I am lost here. Is there a way to bench test the Suction fan? Thanks for all ur help i would never find that #6 i was hunting white wires. You are very helpful, God bless you sir!!!

Maj. Dundee

Check these wires at the fan again with the key on.

RED wire is from the fuse on the battery
BROWN is ground.
WHITE is signal from ECU
BLUE is from fuse #22
