Functional Check of MIL

FUNCTIONAL TESTING:
- Switch ignition on: the MIL must light up. If the MIL does not light up, check wiring according to wiring diagram and/or replace lamp.
- Start engine and let idle: MIL must go out after a couple seconds. If the MIL does not go out after the engine starts, check DTC memory for the engine and/or transmission control modules (malfunctions in DTC memory).
