2015-2016 Transit – 3.2L Diesel – Malfunction Indicator Light (MIL) On – Diagnostic Trouble Code (DTC) P204F
2015-2016 Transit 3.2L diesel equipped vehicles can exhibit the MIL Illuminated with DTC P204F.
The DTC P204F on the Transit 3.2L diesel equipped vehicles is an informational DTC and is set only if DTCs are present in the Reductant Dosing Control Module (RDCM), also referenced as a Dosage Control Unit (DCU) in the PC/ED.
Any DTCs present in the RDCM will need to be diagnosed, repaired, and cleared before DTC P204F will clear from PCM DTCS.
If Diesel Exhaust Fluid System warning message is visible in the Instrument Cluster (IC) or Message Center after resolving DTCs, perform the Exhaust Fluid System Fault Procedure Drive Cycle procedure referenced in PC/ED Description and Operation-Section 2- Diagnostic Methods.
A correction to the PC/ED manual is under development to clarify module name and DTC description.
