D.3 VIEW INJECTOR CALIBRATION

The injector calibration codes are used by the DDEC III/IV ECM to equalize the engine injector outputs. This compensation,

obtained from properly programmed calibration codes, allows the DDEC III/IV ECM to perform optimum cylinder to cylinder

power balancing.

NOTES:

(1) The engine cylinder numbers use TABLE 2-25 (Injector Numbering) page 2-799 to identify the appropriate injector cylinder

calibration code.

(2) Each injector typically has a unique calibration code which is physically indicated on the injector label.

INJECTOR CAL CODE: - CYL #XXX CAL XX

Definition: Indicates the injector calibration that is currently programmed in the ECM.

Typical Range: CYL(#1 to # of cylinders) / CAL(0 to 99)

LAST UPDATE:

Definition: Indicates the engine hours of the last injector calibration update.

Typical Range: 0 to 65000 Hours

TOOL ID#:

Definition: Indicates the tool indentification number used for last injector cal update.

Typical Range: 8 ASCII Characters

# OF CHANGES:

Definition: Indicates the total number of injector calibration updates.

Typical Range: 0 to 255
