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.

To reset the emission malfunction light on a Suzuki Alto, you can try disconnecting the car battery for about 10-15 minutes. This may reset the engine control unit (ECU) and turn off the warning light. Alternatively, using an OBD-II scanner to clear the error codes can also reset the light. However, ensure that any underlying issues causing the light to activate are addressed before resetting.
needs to be done with a diagnostics machine.

hi, disconnect the battery for 5 minutes.
To reset the low tire pressure warning light on a 2002 Vectra, first ensure that all tires are properly inflated to the recommended pressure. Then, turn the ignition key to the "on" position without starting the engine. Press and hold the tire pressure reset button, usually located near the steering wheel or in the glove compartment, until the warning light blinks and turns off. Finally, start the engine to confirm that the warning light has been reset.
