What Cummins code 16355 means

The electrical side of Engine Cylinder 4 Ignition Transformer Secondary Output checks out, but the mechanical part is not doing what the ECM commanded or is out of its adjustment range. Think stuck valves, seized actuators, worn linkages, or a part that moves but never reaches the commanded position.

It lights the amber CHECK ENGINE (warning) lamp. The engine keeps running, but a torque or speed derate may apply depending on the calibration and on how long the fault stays 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 1396 FMI 7 rather than as Cummins code 16355; an OBD-II reader shows it as P2311. Cummins INSITE and Calterm show the Cummins number, the SPN / FMI pair and the lamp together.

J1939 failure mode identifiers (FMI)

FMI 7 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.

FMI	Meaning (SAE J1939-73)
0	Data valid but above normal operational range - most severe level
1	Data valid but below normal operational range - most severe level
2	Data erratic, intermittent or incorrect
3	Voltage above normal, or shorted to high source
4	Voltage below normal, or shorted to low source
5	Current below normal or open circuit
6	Current above normal or grounded circuit
7	Mechanical system not responding or out of adjustment
8	Abnormal frequency, pulse width or period
9	Abnormal update rate
10	Abnormal rate of change
11	Root cause not known
12	Bad intelligent device or component
13	Out of calibration
14	Special instructions
15	Data valid but above normal operating range - least severe level
16	Data valid but above normal operating range - moderately severe level

Questions about code 16355

What does Cummins fault code 16355 mean?

Cummins 16355 is "Engine Cylinder 4 Ignition Transformer Secondary Output - Mechanical System Not Responding or Out of Adjustment". It maps to SPN 1396 FMI 7 and OBD code P2311. The electrical side of Engine Cylinder 4 Ignition Transformer Secondary Output checks out, but the mechanical part is not doing what the ECM commanded or is out of its adjustment range. Think stuck valves, seized actuators, worn linkages, or a part that moves

Which lamp does fault code 16355 turn on?

Amber WARNING lamp: It lights the amber CHECK ENGINE (warning) lamp. The engine keeps running, but a torque or speed derate may apply depending on the calibration and on how long the fault stays active.

How do I clear or permanently delete Cummins code 16355?

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 16355 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.
