by using obd2 scanner from your local garage
Reset the exhaust emission warning light by turning the ignition on and off 40 times. Light codes can be read by the old brake/accelerator press and turn the ignition on.
If its vectra b to reset ECU you have to turn key so all display leds light up then off and do it 8 times if i remember rightly, this resets ECU to factory settings.
disconnect battery for 15 mins...if it come back on there is a reason for the light being on...if so google vectra management light paperclip...hope this helps

it can only be reset with an OBD 2 Scan Tool. If you do not repair the problem that set the light in the first place it will just come back on.
If you do not have a reader with erase capability then the light will turn off by itself after the problem is fixed. Most problems have to do with emission control.
