Fss Reset
On my 99 E320 4-matic with 27k I attempted to reset the FSS after an oil change. I failed and have now locked it up so that the only message showing is "SERVICE DUE 200 MILES". Open the door this shows and it will not go away. --- Any suggestions? Thank you in advance for your replies.

Push the left hand, lower dash button twice and it should pop up. Pressing the right hand button should erase the message and return you to the main screen.
Make certain to close the front door when you attempt the reset or it won't take. It does take a few tries sometimes.

Thanks for the reply. I have pushed those dash buttons every way possible -- door open, door closed, key in, key out, etc. The message will not clear! At one point there was a pair of pages next to the picture of the wrench.

Perform a "hard reset" of the instrument cluster by removing fuses #4, 7, and 10 for a few minutes. Let us know what happens.

THANK YOU -- THANK YOU -- IT WORKED. Pulled the three fuses and let it stand for 10 minutes. Opened the door a couple of times and the dash remained dark. Replaced the fuses and opened the door. The milage and trip returned to normal. We reset the clock and I think all is well. My best guess is the FSS would return to factory specs and we won't see it for 10K.
This site is wonderful. Again thank you for your help. GW |

ILUVMILS - Is there a "downside" to using the hard reset?
Seems easier in many respects to using the dash controls assuming 4, 7 & 10 are all under the hood and not the rear seat.....

The purpose of the "hard reset" is simply to restore functionality to the device that's locked up. In this case, that would be the instrument cluster. It's similar to re-booting a computer. This is a common practice on modern MB's. I've used this method on many systems/components including instrument clusters, door and seat control modules, tire pressure monitors, and many more. If there's a downside to the hard reset, it would be possibly losing stored information (fault codes, freeze frame data, etc).
This procedure is no substitute for re-setting the FSS, though. It merely allows the operator to reset FSS in the normal manner. Last edited by ILUVMILS; 11-01-2007 at 01:36 PM. |
