Another module on the datalink is sending the ECM a value for Motor/Generator 1 Inverter Control Module- Received Network Data in Error: (Multiplexed Data) that is flagged as an error or is out of the valid range. The sensor may be fine; the fault points at the module that broadcasts the value or at the datalink wiring.
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 9436 FMI 19 rather than as Cummins code 16659. Cummins INSITE and Calterm show the Cummins number, the SPN / FMI pair and the lamp together.

Questions about code 16659
What does Cummins fault code 16659 mean?
Cummins 16659 is "Motor/Generator 1 Inverter Control Module- Received Network Data in Error: (Multiplexed Data)". It maps to SPN 9436 FMI 19. Another module on the datalink is sending the ECM a value for Motor/Generator 1 Inverter Control Module- Received Network Data in Error: (Multiplexed Data) that is flagged as an error or is out of the valid range. The sensor may be fine; the fault points at
Which lamp does fault code 16659 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 16659?
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 16659 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.
