If fault 3361-3 is active, refer to the diagram above, load test and drag test ACM connector J2 pins 46 and
48, and DEF Supply Module 12 way connector pins 9 and 10. If the fault is inactive, return the unit to
service. Do not replace the DEF Supply Module.
Solution
There is a calibration fix to resolve this code. Please update the calibration using NETS. Do the GET as
"Change Parameters," Send, Receive, and Program.
Note: Verify that the aftertreatment fuel line has been updated from a solid line to a flexible line per
REHS9170 prior to updating the calibration file. Failure to replace the line will cause false AFT fuel
pressure codes.
Note: 1569-31 SCR Tamperproof Warning and Protection System Inducement Severe will also set with
3361-3.
