E63 / E64 6 Series (2004 - 2010)
The E63/E64 BMW 6 Series builds on BMW's sporty heritage with aggressive lines and an incredible motor to back the design up. Available in coupe and convertible trims with a standard 4.8 liter engine producing 360 horsepower and 360 lb-ft of torque, the 6-series is a popular choice that exceeds expectations.

Rollover Control module

Hi,

My rollover control fault still eludes me. I've now bought 3 different replacement modules to try and get rid of my "Restraint systems faulty" error. Now I finally found an exact part number replacement (65776950640 - was very hard to find) and having just fitted it - no difference! Still the same 09402 fault code...

I find it hard to believe that I've found another module with the exact same problem so I guess the issue is something else other than the module. Does anyone know about this code? I've seen it referred to as "Rollover controller - internal fault" on E93 forums, and also listed elsewhere as "Front left sensor", whatever that might be. At least if there is such a sensor that might explain why replacing the ROC doesn't fix the problem.

To be clear the rollover system hasn't deployed. The fault started happening one day when (maybe a coincidence) I was messing around in the trunk trying to find the TCU (I know it's behind the seats now).

The 9402 problem is also referenced in a TSB (http://www.aboutautomobile.com/Equip...+Series/Airbag) but I'm not sure what that means or what I should do about it.

Any ideas? I'd have been better taking it to the shop with the amount of time and money I've wasted on this problem already but I hate to give up.

Cheers

-- Chris

Oh and just for fun the 9402 code is also referenced as "SGM fault code "9402 and/or 9404 - Front sensor wrong component". Vehicles prior to 03/04 production must also have the upfront sensors replaced using P/N 65 77 6 951 595 or later. " in reference to a software upgrade "CIP 20.00.00 TIS released today 12/28/05".... However the referenced part number seems only applicable to 5 and 7 series.

I have no idea what to do next with this one

Have you gone thru the process of re-seating the roll over bars?

No I haven't. I can't find any reset procedure specifically for the E64, do you know how to do this reset or is it the same as an E46 or other BMW model?

Cheers

Thanks Herb. Lots of the info in there is for people who have triggered the bars, which I have not. I think I've figured out how to test the bar pop up using DIS so I shall try that and then reseat them.

The most interesting line of enquiry for me right now is whether there are sensors external to the ROC that could be part of the problem. I've seen a couple of diagrams that say there's a front left and front right acceleration sensor that talk back to the ROC. They're shown as being behind the headlights but the diagram is vague. I'd like to pull and test these sensors if they actually exist and see what the scanner thinks about that. I couldn't find them in TIS but I can't find much in there often. Does anyone know if they exist and if so where they may be found

You would need a copy of WDS to get the detailed wiring diagrams that are not in INPA or DIS. If you run the ECU test in the ROC module (SZM) I think, you should be able to reset the module. ISTA/D would probably have everything you would need.

I know this is a couple years old by now but just incase you haven't found the answer or if anyone else comes across this thread.....
There are 2 crash sensors mounted directly on top of the front bumper reinforcement bar just to outside of the width of the radiator on each side. I believe they are only accessible with the front bumper cover removed. I don't have a pic right now but I will take 1 in a few minutes for you to see what I'm talking about.

It appears to be behind the rear seat on the right hand side.
