Read all safety instructions in the "Safety Information" section of this manual before doing any procedures.
No DTC conditions detected
Can only determine if ECM has detected continuous DTCs detected during an
Output Circuit Check. DTCs generated during an On-Demand Test such as KOER
Standard Test can only be accessed by an EST.
ECM / Injector Drive Module (IDM) software is incompatible
Possible no start – low power
Field replacement ECM or IDM mismatch
Program ECM or IDM. May require ECM or IDM replacement.
Engine Family Rating Code (EFRC) / ECM configuration mismatch
Possible hard start and no start or low power condition
Wrong EFRC selected for the ECM strategy programmed in the module.
Check EFRC and verify that it matches the ECM strategy level. Reprogram the
ECM or change the EFRC as required.
Manufacturing defaults selected.
Very low power (25 hp).
Programmable parameters for the ECM were never programmed in module.
(Usually occurs in new vehicle or new module).
Program ECM.
Engine using field default rating.
Low power (lowest rating in engine class) and vehicle features not working.
Programmable parameters for the ECM incorrectly programmed in module.
Program ECM.
Invalid EFRC
Possible hard start and no start or low power condition.
Wrong EFRC selected for the ECM strategy programmed in the module.
Check the EFRC and verify that it matches the ECM strategy level. Reprogram the
ECM or change the EFRC as necessary.
Follow all warnings, cautions, and notes.
