NOTE: The Mitsubishi ECI system requires a special tester (Mitsubishi ECI Checker - MD998406) to be fully diagnosed. However, some checks of individual components may be made using regular shop test equipment.

CAUTION: Be sure ignition switch is off when disconnecting connectors from control unit. While testing, be careful not to bend any pins and do not touch more than 1 pin at a time with meter lead as meter or ECU could be damaged.
