This is not an electrical fault on a sensor. FMI 31 means the ECM has detected that the named condition for Additional Auxiliary Diagnostic Codes Logged is true. The fault code itself is the message; the fix is to find out why the ECM believes the condition exists.
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 1484 FMI 31 rather than as Cummins code 211; an OBD-II reader shows it as P0700. Cummins INSITE and Calterm show the Cummins number, the SPN / FMI pair and the lamp together.

J1939 failure mode identifiers (FMI)
FMI 31 is highlighted. The FMI is the second half of every J1939 fault and tells you how the component failed; the SPN tells you which component.

Questions about code 211
What does Cummins fault code 211 mean?
Cummins 211 is "Additional Auxiliary Diagnostic Codes Logged - Condition Exists". It maps to SPN 1484 FMI 31 and OBD code P0700. This is not an electrical fault on a sensor. FMI 31 means the ECM has detected that the named condition for Additional Auxiliary Diagnostic Codes Logged is true. The fault code itself is the message; the fix is to find out why the ECM believes the condition
Which lamp does fault code 211 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 211?
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 211 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.
