The reading for Motor/Generator 1 Inverter Phase V Power Module Switch Temperature 1- Data Valid but Above Normal Range : Least Severe Level is believed to be correct, but it has gone slightly above the normal operating range. This is the least severe of the three "above range" levels (FMI 15, 16 and 0); it is usually an early warning rather than an immediate problem.
No dash lamp is attached to this code in the Cummins fault table. It is logged in the ECM and shows up in Cummins INSITE (or any J1939 tool reading DM1 / DM2), but on its own it does not light a lamp.
On a generic J1939 scan tool, or on the dash of a Freightliner, Kenworth, Peterbilt, International or Volvo chassis, the same fault is shown as SPN 9088 FMI 15 rather than as Cummins code 16577. Cummins INSITE and Calterm show the Cummins number, the SPN / FMI pair and the lamp together.

Questions about code 16577
What does Cummins fault code 16577 mean?
Cummins 16577 is "Motor/Generator 1 Inverter Phase V Power Module Switch Temperature 1- Data Valid but Above Normal Range : Least Severe Level". It maps to SPN 9088 FMI 15. The reading for Motor/Generator 1 Inverter Phase V Power Module Switch Temperature 1- Data Valid but Above Normal Range : Least Severe Level is believed to be correct, but it has gone slightly above the normal operating range. This is the least severe of the
Which lamp does fault code 16577 turn on?
No lamp: No dash lamp is attached to this code in the Cummins fault table. It is logged in the ECM and shows up in Cummins INSITE (or any J1939 tool reading DM1 / DM2), but on its own it does not light a lamp.
How do I clear or permanently delete Cummins code 16577?
An active code goes inactive on its own once the condition is gone; the inactive record stays in the ECM fault history until it is cleared with Cummins INSITE (or a J1939 tool that supports the DM3 / DM11 clear). If the code keeps coming back because the part is gone, disconnected or not worth repairing, the lasting fix is to disable fault 16577 in the calibration: upload your .xcal to the ECFG Superstore file service, custom DTC delete from $150 (up to 30 codes), full DPF / EGR / SCR delete $500, and flash the returned file with Calterm or INSITE.
