The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.Problem
The diesel exhaust fluid (DEF) quality sensors are susceptible to seeing the following fault codes.
Table 1
J1939 CDL Code Description
3516-2 3100-2 Aftertreatment #1 DEF Concentration: Erratic, Intermittent or Incorrect
3516-12 3100-12 Aftertreatment #1 DEF Concentration: Failure
3516-16 E1365 High Aftertreatment #1 DEF Concentration
3516-18 E1364 Low Aftertreatment #1 DEF Concentration Solution
The latest software available in SIS has improvements in it related to the DEF quality sensor and these fault codes.
Ensure that the latest engine and aftertreatment software is installed prior to any hardware replacements.
Ensure that the latest DCU software is installed ( 539-3577 Engine Software (24V DCU) or 539-3576 Engine Software (12V DCU)).
In addition to the troubleshooting for these fault codes in SIS web, ensure that DEF quality is checked with both a refractometer and the 466-8796 Test Strips as outlined in Diesel Exhaust Fluid Quality - Test procedure in SIS.
Keep the DEF tank full when machine/engine will not be operated for an extended period of time to help reduce manifold exposure to ammonia gases in the DEF tank.Have seen cases of contamination where the test strips will not detect it if contamination is not hydrocarbon-based. In these instances, the DEF will appear to be cloudy when doing a visual comparison to a good, clean DEF sample.While working through issues related to these particular fault codes, email Blunier_Derek_W to provide troubleshooting information and
