Introduction
The problem identified below does not have a permanent solution. Until a permanent solution is known, use the solution that is identified below.Problem
There have been some instances of faults with the 459-7216 DEF Injector & Mounting Gp. The faults can lead to the Diesel Exhaust Fluid (DEF) injector not dosing correctly. Diagnostic trouble codes and operator inducements may become active due to these faults.Solution
Follow the correct troubleshooting procedure for any diagnostic codes related to the DEF system. Refer to Troubleshooting for the correct procedure. Diagnostic code 3361–5 Aftertreatment #1 DEF Dosing Unit : Current Below Normal has been reported, which may lead to operator inducement diagnostic codes 5246-15 Aftertreatment SCR Operator Inducement : Severity : High - least severe (1) and 5246-16 Aftertreatment SCR Operator Inducement : Severity : High - moderate severity.If the troubleshooting procedure indicates a DEF injector fault, perform the following procedure:
Ensure that the latest engine software is installed on the engine ECM. Refer to Troubleshooting, ECM Software - Install for the correct procedure.

(1) DEF injector part number
(2) Cavity number
Record the DEF injector part number (1), serial number, and cavity number (2).Note: The cavity number will be either a "1", a "2", or a "3".
If the DEF injector serial number is between "SN150702094314" and "SN160722000000" and the cavity number is "1", continue with this procedure.If the DEF injector serial number is outside of the range specified above, proceed to Test Step 4.If the cavity number is "2" or a "3", proceed to Test Step 4.
Install a replacement DEF injector. Refer to
