DTC C42400 & C46B86 ???


Recommended Posts

CEL went on over the weekend - still on today - engineering test mode shows the subject codes as history, but I can't find them anywhere on the internet to learn what they car.  The car runs and sounds normal.  We did the "check fuel inlet" message a couple times recently, but not now not for the past week or so.

 

Anyone else see these codes or know what they mean?

Best possible explanation I've seen so far is that the code points to an error to do with the GPS system receiving invalid data: 

 

From 13FFH who posted in this Ford Fusion Hybrid forum thread: 

http://fordfusionhybridforum.com/topic/8431-yellow-engine-and-hist-dtcs/

Service department extracted a bunch of "U" codes one of which was U046B:86-08, which looks like the C46B86 that was shown in the DTC ET window. U046B is "Invalid Data Received From Global Positioning System Module".

 

But that kind of error would not seem at all related to your engine issues.

My engine light is on as well, for the last 3 days.  I have two error codes:

 

C45282

C46B86

 

Car is running just like it always does and mileage is good.

Is it time to get ForScan?

 

From ForScan:

 

===FCIM DTC U0452:82-08===

Code: U0452 - Invalid Data Received From Restraints Control Module

 

Additional Fault Symptom:

- Alive/Sequence Counter Incorrect/Not Updated

 

Status:

- Previously Set DTC - Not Present at Time of Request

- Malfunction Indicator Lamp is Off for this DTC

 

Module: Front Controls Interface Module

 

===END FCIM DTC U0452:82-08===

Hey ?️

 

This morning engine orange light came in.. no strange noise, nothing... and in the engineering mode I saw the DTC C42400 - Looked over the internet and find nothing except maybe a leaking transmission....

I have a Titanium C-Max Energi 2017 with 21800 miles ?

 

Any idea?

 

Update: resetting all the 3 modules and no more issue.. ?
