Hi please can you tel me where to find the names for the airbag codes, i have code numbers 1039 and 2038, thanks

Which airbag ECU is it?

Its a R75
ywc 001180
p/n 602 86 49 00

I have another one but it also gives me a code 1041, then i get,

erase error codes
fail code $22
attempt erase history update

Temic or AB Autoliv?

Autolive, its a rover 75 200d 2004
Thanks

When I run these through an old Snap-On Modis I get these definitions:-

1039: Rear right pretensioner Internal DCU fault
2038: Rear left pretensioner Internal DCU fault
1041: Airbag of Pretensionr DCU incorrectly configured

If you could give me a couple of days I should be able to run them through a T4 and see what that says.

This would give me a much higher confidence in them.

Thank you for you help,
The ECU that has the code 1041, with the fail code $22, is the one that was fitted to the car from the start

The other one codes 1039 and 2038 is one that i got from e bay
Thank again John

From the Rover T4 tool

1039 Rear right pretensioner internal DCU fault
2038 Rear left pretensioner internal DCU fault
1041 Airbag / Pretensioner or Side impact sendor DCU incorrectly configured

Thank you again, but this car dos not have rear pretensioners
So am i right in saying the ebay ECU that i fitted does not fit my car

If I refit my original ecu with code 1041 is it both pretesioners that i should change and can you please explain to me DCU, and how to configure them if they need it

Thanks

On their wiring diagrams Rover refer to the airbag/SRS ECU as a "DCU".
I don't know what the "D" stands for, but there is only one electronic box and it connects to all of the airbags at least according to the wiring diagrams.

I am not an expert in Rover airbag problems. All I can say is that the codes would indicate an internal ECU (or rather, DCU) fault.
My expertise is with reverse engineering the T4 system and giving customers something that functions as near as I can get to (or sometimes better than) the original T4.

I can't necessarily help with fixing the cars, I don't own a Rover 75 and I have never fixed one.

Concerning the replacement ECU. I have no idea what it means if it is "incorrectly configured". Is it a brand new unconfigured ECU (DCU)? Maybe it is detecting that there are no rear pretensioners at all and so it thinks it's in the wrong car?

Maybe if you supply it with three rear pretensioners in the form of resistors then maybe it would work? Sorry but I don't know.

The wiring diagram shows the following items attached to the ECU (DCU):-
Pre-tensioner left U104
Pre-tensioner right U105
Pre-tensioner rear right T224
Pre-tensioner rear centre T226
Pre-tensioner rear left T225
Drivers airbag U106
Passenger airbag U102

U104 and U105 appear to be connected on the same circuit in series, so I suppose they both get fired at the same time.

Hi, Is it possible that you have a wiring diagram that i could look at for the air bags
Thanks John
