3 times, 3rd time you leave the ignition on. Works until 2005.

As far I as I have experienced with my 2002 2.5 CRD, this process will display the codes....from the oldest to the newest...but does not erase the codes.
I have tried all the supposed tricks to erase the codes such as disconnecting the battery, disconnect battery and short positive cable to ground for 10 minutes etc. but nothing seems to work.

It seems to me that to erase codes that have been logged...a scanner needs to be used and that the early KJs use the PCI format while later (2006?) KJs need a scanner that does CAN bus.

To actualy clear any offending warning light and "pings", you need to first fix the problem and then the error clears after a certain amount of running cycles.:shrug:
