What causes a 420SEL’s malfunction indicator light (MIL) to illuminate?

While resetting a malfunction warning light at home is technically possible, doing so is not advisable. The check engine light is typically a sign of a problem in one of your 420SEL's systems, and simply resetting the light will not address the underlying issue.
