I saw a holden techie doing it to my car by pressing and holding a few buttons where the mode is for trip computer. Now does anyone know what buttons to press and hold to do this? Sorry if this is a dupe i used the search didnt see anything.
I think what ya want is to hold down mode and up and then turn your key to either ignition or start and release. I do that all the time, love a digital tacho. -Adrian
I've already got the digital speedo on my normal dash. Just disabled the speed alarm to do it. -Adrian
that's the loaded software version date in YYMMDD format. not sure how you'd have 60 anywhere in there, but that's what the writeup I have says (SC mag tech handbook 4) does anyone here know why this diagnostic mode no longer works in my berlina? it used to, but since the CAS started playing up it stopped working
