Porsche reset computer - 2000 Porsche 996

after replacing the car battery you have to reset the computer in the porsche. what happens is after battery is dead it shuts off the computers, and thats why you get that message

Clearing Codes, clears all data, then all the emission
monitors have to run again, or you won't be excepted
to inspection

Clearing codes & data,has nothing to do with diagnosing
why you got the fault codes & fixing the problems

How would clearing a dash light help pass inspection?

Before you got down the street two houses, the light would
be back,the car has a failed system ,thus the light on the
dash after the motor is started.

You cleared all data,now a shop can't even work on it
You removed all vehicle history & codes

Flat bed it to a shop & they will make the repairs you neglected
to do, while trying to get hundred miles before the parameters
on a failed system went out of range & the dash light came back

Need to study OBD 2 Systems on the internet & leave the vehicle
work to the pros

hi,

Try this procedure. Porsche can be hit or miss with reset procedures. Sometime a Porsche scan tool is needed.

1. Enter the vehicle and make sure that all doors are closed.

2. Push the odometer reset button while turning the ignition key on.

3. Continue holding down the odometer reset button for approximately 10 seconds until the "Service Reset" message appears in the information center.

4. Release the odometer reset button and press the reset button on the bottom of the wiper stalk.

5. It may take a few attempts with this procedure.

6. If the light is not reset, then a Porsche compatible scan tool will be required to reset it.

sorry to say but this car needs the pst2 (porsche system tester2). this is a scan tool and only the dealer has, you will need to have the dealer reset it,

Hello. There are two ways to turn it off. The recommended way is to have the car's computer scanned and reset. When it is reset, the light will go off. The other way is to disconnect the battery for two minutes. When the battery is reconnected, the light will be off. Joe

4 thumbs up please. thank you.

The easiest way to reset service light on any car is to unplug negative (black) cable from battery for 2-3 minutes. If the problem is fixed, the light will be off upon cranking car again. Hope this helps. Please leave feedback.
