Circuit breaker wire and fuse under hood, right side, was purposely removed and on 2005 Mercedes-Benz C240

Reconnected. Since then, warning light has come on a few times. This has never happened prior to disconnection. What else could have been effected? Thank you

Maybe a power surge? Start by Checking all fuse w/ proper circuit tester, step on w/ owners manual
