DME Hard Reset

[Schnell Gelb]

Hard reset of the DME. I have a suggestion to reset the DME on my 2001 Boxster S. The procedure would be the same for a 996 and other years of Boxster ? So the issue may be of wide interest.

Question is how to do it correctly. Obviously there is  a potential to cause great damage.

What is the best resource to use to follow to do a Hard Reset of the Bosch Motronic 7.2 DME ,please.

This is the best I found but is 997

No such thing as a "hard reset".

You can reset the drive mode for the throttle/idle as well as Tiptronic drive shift points.

For both of those just disconnect the battery for about 5 minutes.

 

Do a throttle adaption on egas cars and then drive as you normally would to "relearn" throttle, idle, and shift points.

It is normal for the car to run rough during the "relearn" process - but it should only take a few miles.

Thank you Loren. Sorry I posted this in the wrong Section.

I have used this procedure since the 80's to clear bad data and do a hard reset on the KAM of all kinds of manufacturers brands and have never had a problem with it. While simply disconnecting the battery will reset in a lot of cases, it depends on the internal circuitry if the capacitors circuits have enough internal resistance to deplete them. That said I will not advise anyone who is uncomfortable about this to do it even if you remove the battery and place it 10 feet from the car...lol I have seen many many fried radios, amps, CD changers, control units,by accidentally reversing polarity,  from people in the Auto business (mostly salesmen) just from attempting to swap a battery or jump a car.This link is from a RangeRover site.

 

Since I am not going to advise anyone to do this (even if you remove the battery completely and put it 2 arms length away from the car) I will not have to advise you to remove any accessory( ie GPS, Ipod ect ) that has batteries., any additional batteries like for high powered radio, any high powered amps or capacitors.
