The ECM knows something is wrong with EACS ISG Temperature SENSOR but cannot narrow the cause down to one of the standard failure modes. Treat the whole circuit and the component as suspect and follow the Cummins troubleshooting tree for the code.
It turns on the red STOP ENGINE lamp. Cummins classes this as a fault that can damage the engine or aftertreatment if ignored: stop as soon as it is safe to do so. Many calibrations also apply an engine-protection derate while the fault is active.
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 516180 FMI 11 rather than as Cummins code 13586. Cummins INSITE and Calterm show the Cummins number, the SPN / FMI pair and the lamp together.

J1939 failure mode identifiers (FMI)
FMI 11 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 13586
What does Cummins fault code 13586 mean?
Cummins 13586 is "EACS ISG Temperature SENSOR - Root Cause Not Known". It maps to SPN 516180 FMI 11. The ECM knows something is wrong with EACS ISG Temperature SENSOR but cannot narrow the cause down to one of the standard failure modes. Treat the whole circuit and the component as suspect and follow the Cummins troubleshooting tree for the code.
Which lamp does fault code 13586 turn on?
Red STOP lamp: It turns on the red STOP ENGINE lamp. Cummins classes this as a fault that can damage the engine or aftertreatment if ignored: stop as soon as it is safe to do so. Many calibrations also apply an engine-protection derate while the fault is active.
How do I clear or permanently delete Cummins code 13586?
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 13586 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.
