Saab 900 check engine light reset?

To reset the check engine light on a Saab 900, you can use an OBD-II scanner to clear the trouble codes stored in the vehicle's computer. Alternatively, you can disconnect the negative battery terminal for about 10-15 minutes, then reconnect it, which also resets the system. However, ensure that any underlying issues indicated by the check engine light are addressed before resetting to avoid potential engine damage. Always consult your vehicle's manual for specific instructions related to your model year.
