Holden VE Commodore Engineering Mode

[Blacky]

I was waiting around in the car the other day and tried to figure out how to reset the 15,000 service warning that had just come on.
Finally figured it out:
1. Hold down the "Trip" button while switching on the ignition.
2. Press the "Reset" button for 5 seconds.

I also stumbled on this one while trying to figure it out: Enter engineering mode which displays a number of common PIDs in the dash display:
1. Hold "Reset" while switching on ignition.
2. Scroll up/down to display various PID values.

Some of us still drive 9 year old Commodores :doh:, but handy to know for anyone else.

Those old VT jiggers do it in the cluster as well Ross.. But I reckon just quietly you probably know that... :-)
