First post to the forum so I'm sorry if this is in the wrong place, but this forum seemed to have the most discussion about DTCs.  Let me know if I should post this somewhere else.

 

Bought my 2013 Hybrid a few months ago, just crossing the 10K miles and the indicator came on to get my oil changed.  Crazy schedule with spring break so instead of going to dealer I just went to a local Firestone. I had noticed that in addition to the oil change warning there was also a yellow engine warning.  I guessed that was just another indication to get the oil changed.

 

Got the oil changed but the engine light was still on.  I thought it might go off after a few minutes--that happened when the tire pressure light came on during a cold snap and I put some air in, light went away a few minutes later.  But this time the light stayed on even when I got home 15 minutes later.

 

Google brought me to this forum and I saw how to look up the DTC.  But when I got to the screen it did have three codes, all three are marked as HIST rather than current.  The three codes are:

 

C15900

C46B86

F00316

 

I've seen some of them referenced on the forum without saying what they are.  My question to the smart crowd here--I have two longish trips coming up in the next few days (at least 5 hours driving Thursday, then 3 hours driving on Friday and Sunday).  Are these benign codes or do I need to worry?

 

Thanks.

All of the DTC codes I have ever seen are letter#### format.  While I think that may be a code generated by your car, I don't think it is a OBDII code.  I just looked through several diagnostic manuals for the 13 and 14 fusion and noting remotely pulls up with those codes for DTCs.

Hmmm, those are definitely the codes I'm seeing. I've attached a photo to verify.

Is the CEL and/or the DTC's still there after three drive cycles?

I believe those codes are Ford specific. A Ford dealer can read the codes and tell you what they are. Did you run a Vehicle Health Report while the CEL was on?

The DTCs still show up (just checked) after driving about 4 or 5 times today.

I didn't run a vehicle health report--is that next step?

Running a VHR is always a good idea when there is strange behavior going on. You should be setup for that if the dealer properly set you up in the SyncMyRide website.

Hi Ryan Garcia, 

 

Let me know if you have any questions about running a Vehicle Health Report. Here are the instructions: http://support.ford....nc-myford-touch As far as the codes go, I suggest checking with your dealership.

Part of the run cycle on many cars (not sure about the fusion) is that it requires a start from a cold engine, so you may have to wait quite a while before it will recognize another drive as a new cycle session.

I too experienced a yellow wrench and now have one of the codes mentioned above in my history (C46B86). I played around with grouping the digits into two's and threes', coverting to hex, trying to make it fit into the normal P#### format. Then one day I was looking at TSB 13-11-11 and it hit me that letters were allowed in the DTC code as well. So, I made the assumption that I what I was seeing was two codes, P0C46 and P0B86 and lo and behold, those are valid codes pointing to the hybrid battery. Made sense to me since this is a hybrid car, but for the validity of the codes to the actual shown in DTC history is still speculation. I did look at the codes Ryan Garcia posted and there are valid codes for all except for the F00.

It's an AH HA moment!  Thanks for posting.

Hoping to confirm or blow my theory out of the water in the next week or so with a visit to the service department to extract my historical codes.

Theory blown. 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".
