I am trying to turn on the autolock function on my '99 GS400. A friend on mine has a Professional OBD II scanner where he works. He let me use it to customize the C-BEST settings. I can see and change other options but I can't turn on the autolock function listed below. Everytime I change it to ON, it tries to set it, then comes back saying that the ECU cannot be changed. This scanner has newer code (version 8.1a) than what is listed on the first page of the C-BEST settings and does list EVERYTHING that is listed in the C-BEST list. Is there something else I need to do to get this function turned on, beside taking it in to the dealer? Or is this something that ONLY the dealer can do. I was successful in changing other options.

2.DOOR LOCK AUTO LOCK Function to lock the doors when the vehicle reaches a certain speed.

ON/OFF GS430/300

I think it would be nice to have all of the doors lock automatically when I hit a certain speed(like 5 ~ 10MPH)

 

I believe that this is only available on the 2001 and up GS's. note that its says GS430/300. I'm 99.9% sure about this.
