E38 (08 C6 ZO6) - Speed Density "Service Traction System" P0102

[Adjellin]

I have an issue with my 08 C6Z displaying the "Service Traction System" message on the DIC and disabling traction control. My Autocal displays a P0102 code due to the missing MAF and when I clear the code, the traction light will go off but returns 5 seconds later with the same P0102 code.

I understand that the P0102 code will be thrown with the speed density tune but I'm wondering if there is any way to get my traction control system to not disable because of this?

The patch has been installed and I don't have a CEL, just the Traction Control light.

Any help would be greatly appreciated!

Thanks,
Adrian

BUMP

Anyone have any ideas?

There is a traction control patch that needs applied for SD.

Thanks for the reply!

I will ask my tuner to look for it and send me a new file.

Would you happen to know which patch is the correct one?

I keep finding B9901, B9902, and B9903 through research but no definite answer for which is the TCS patch.

Thanks,

Connect your FSV2 to your laptop, open the V7 (V7.5) tunetool, in the Engine folder you will see a red subfolder "Operating Syste,m Patches", go into this folder, you will see B9901, B9902, B9903, they each have descriptions.

Joecar,

I'm pretty sure we have it correct in the tune but would you be able to open the attached file and confirm?

Thanks for your help!
