Toyota Urban Cruiser 1.4 D-4D Firmware 89663-52K67.MPC

89663-52K67.MPC is a cataloged engine-control firmware file for the Toyota Urban Cruiser 1.4 D-4D. The 89663-52K67 identifier belongs to Toyota’s engine-control calibration part-number family.

The engine control module manages diesel engine operation using sensor readings and stored calibration data. Its functions include controlling fuel injection and coordinating engine operation under changing driving conditions. The catalog identifier alone does not establish a specific change to those functions for this calibration.

How to read the catalog entry

The filename combines the calibration identifier with an .MPC extension. The related catalog entry 89663-52K67 identifies the same calibration without the extension. No stock or modified variant label is included in the listed name.

For diagnostic or identification purposes, the complete calibration number is more useful than the part-number prefix alone. It distinguishes this Urban Cruiser entry from other Toyota engine-control calibrations.
