Fault Code 3714 Active with No Other Active
Fault Codes
Core Issue
Product Affected
• All electronically controlled engines
Root Cause:
Due to a software issue, Fault Code 3714 may become active after adjusting INSITE™
electronic service tool multiplexing parameters or troubleshooting other active selective
catalytic reduction (SCR) related fault codes.
Confirmation
For some units that have a hardwired (analog) diesel exhaust fluid (DEF) tank level and
temperature sensor, Fault Codes 285 and 4572 will become active due to a software
parameter defaulted to mulitplexed. Even if INSITE™ electronic service tool is adjusted
correctly to reflect the analog sensors, Fault Code 3714 will become active.
Other units may trigger SCR related Fault Code(s) 1682, 1683, 1713, 2976, 3151, 3238,
3241, 3258, 3261, 3423, 3425, 3558, 3559, 3563, 3567, 3568, 3572, 3574, 3575, 3596,
3748, 4156, 4169, or 4769. These fault codes will lead to Fault Code 3714 (inducement)
within 1 hour and will eventually lead to Fault Code 3712 (severe inducement) if not
addressed. Even when those active fault(s) are addressed before Fault Code 3714
becomes active and are cleared, Fault Codes 3714 and 3712 will still become active due
to a diagnostic not verifying that the fault codes are cleared.

To correct the issue, troubleshoot all active fault codes. Verify all fault codes, except a
possible Fault Code 3714 or 3712, are inactive. Use INSITE™ 7.6 electronic service tool
or higher to calibrate the engine control module (ECM) with the latest calibration from
QuickServe™ Online or the April 2013 INCAL Calibration DVD. Once the ECM has the
new software, all fault codes will be cleared.
