(1) Repair Procedure
• When replacing injectors with QR codes, or the engine ECU, it is necessary to record the ID codes in the ECU. (If the ID codes for
the installed injectors are not registered correctly, engine failure such as rough idling and noise will result). The ID codes will be reg-
istered in the ECU at a MITSUBISHI dealer using approved MITSUBISHI tools.
