  1. Check Horn Fuses (F20 and F24) and Horn Relay (R2) in the fuse box under the hood. C131 is the 2 pin connector for the horn located on the passenger side front.  You'll need to remove the front lower cover (looks like 6 push pins and 7 screws).  Check horn by applying 12 V to horn directly.

     

    If above okay, spend less than $30 for an OBDII ELM327 module and the ForScan App and scan modules for DTCs.  There are many for the Horn which should help isolate the issue from the horn switch, clockspring, BCM, relay, and to the horn itself.

     

    Thanks, I checked the relay and F20 but not F24, I found where the horn was located in the wiring diagram and figured I would have to remove the bottom cover. I do have an ELM327 and ForScan and when I checked  for other issues last week there were no indications of issues, but probably need to test again. 

  2. So, since you didn't mention the dash going dark, I'm assuming you had 12 V power.  I'd be somewhat concerned as you apparently didn't get a warning message.  I don't recall anyone having this happen to them. 

     

    If "D" went dark and the battery symbol went to zero and the 12 V system apparently was up, it may be an issue with the SOBDMC (the hybrid power control module) or the BECM (battery electric control module).  Unless you want to pay the dealer $100 or so for a diagnostic scan, isn't it time to invest in the ForScan App so you can scan these and other modules as I indicated to you when you ask about the PID for the transmission fluid temperature in another thread.  :)   There may be DTC stored as maybe a module lost power, couldn't communicate with other modules and so forth.

    Actually I have the Forscam app and odbll module just didn't think to check since there was warning. Thanks for jogging the memory!

  3. Transmission Temperature "Trans" "221E1C" "(((SIGNED(A)*256)+B)*(9/8)+320)/10" "-40" "260" "°C" "TCM"

     

    got from  ford focus site.  I think this is the PID i used on my galaxy 5 and the obd2 elf scanner

    Looking at this formula an see the *C - does this display in Celsius?  also not sure what character to use to represent the degree mark "°C"  seen here.

     

     

    Why not use the ForScan app and you won't have to worry about entering PID data.   I believe the data for TFT is buried somewhere in this forum but couldn't find it with a quick search.  

     

    Here's a link of how to convert the Scan Gauge code TFT shown below to the engine link format.

     

    TXD: 07E6221E1C

    RXF: 0462051E061C

    RXD: 3010

    MTH: 000900500020

    NAM: TFT

    So I downloaded the ForScan app but it tells me the TFT is supported.
