2000 S40 - Check Engine Light S40-V40

Just go to Autozone. They will pull the code and reset the check engine light for free. They provide this service because if the code says you need new spark plugs or an O2 sensor, well you get the picture. ;) That will tell you for sure if it was the battery that set it off.

Some 00's and 01's had overly sensitive settings in the software and do require a software update. If this is your first CEL at 30,000mi that should be unlikely but if it comes back, have the dealer do the upgrade.
