[s-cars] Resetting ECU - Clearing Fault Codes

[Mark Pollan]

Pulled fault codes the other day and got 2413.  Appears my MAF is amiss as
well.  I cleaned her up (wires and connectors) and now want to clear the
codes.  Scott M's site indicates accessing the ECU via the footwell carpet
route.  Is this absolutely necessary or can I merely disconnect the battery?

Regards,

P.S.  Doing Eibach/Bilsteins starting in about an hour.
