2011-2016 Fiesta 2012-2016 Focus Inadvertantly Setting A P0606 Diagnostic Trouble Code Along With U3003 Or Other U-Codes Present Or Stored
Some 2011-2016 Fiesta and 2012-2016 Focus vehicles may set a P0606 Diagnostic Trouble Code (DTC) when battery or charging system issue is present or in the event of a dead or parasitic battery drain condition.
Please diagnose and repair any U codes that are present or stored before condemning the TCM or any transmission hardware.
Stored codes may have been set during new vehicle shipment or if the vehicle had a dead battery and was jump started.
DTC’s should be cleared and the charging system and battery inspected according to Diagnostic (PC/ED) manual or Workshop Manual (WSM), Section 414-00 for normal diagnostics.
DTC P0606 Diagnostic chart and repair action in the Workshop manual is being updated to redirect the diagnostic in the event of the accompanying U codes.
