Tech Help / Wiring diagram for FX 5.7 (2015)

« on: July 29, 2016, 12:20:38 AM »

Hi everyone,

I am trying to avoid a long drive to a dealer, to find out why my 12V fuse panel on my 2015 FX 5.7 isn't getting 12V. The DC-DC is fine, because the dash and ECU are working. Just the 12V fuse panel (for lights, horn. ABS, dash backlight etc) isn't receiving 12V. I am looking for a wiring diagram - anyone have one?

PS I have checked the high voltage fuse after the DC-DC and it has continuity, according to my Ohm meter.

Thanks,
Phil

Tech Help / DC-DC regulator

« on: July 06, 2016, 10:58:15 PM »

Has anyone ever had a failed DC-DC regulator? I have a 2015 FX 5.7 and all 12V accessories are dead. (lights, horn, ABS, backlight to dash) (The 12V to the dash screen and motherboard are fine).

I checked high voltage DC-DC fuse (in cable harness) and it is fine. All 12V fuses are fine. I am convinced this is not a loose wire. Probably not a ground issue given that I have 12V on the other line out of the DC-DC for motherboard and dash screen.

Could the DC-DC has 2 12V circuits and internal fusing?? Anyone else had DC-DC problems?

(Originally, this was an intermittent no-12VDC problem based on start-up temperature outside, and got worse and worse until now there is 12V at all on the accessories. So it wasa slow failure...like how a DC-DC can fail.)

Anyone able to help me?

Thanks,
Phil Daniels

Now it's summertime, and the 12V is always gone. Lost it for good last week. It was intermittent even on hot days and then it went out completely. No lights, horn, ABS pump or indicator lights. Dash still works but is not backlit. I checked the 12V fuse panel and all fuses are fine, and so none of the 12V fuses are receiving voltage.

Why the dash still works is beyond me, it must be powered of 5V somewhere else? Maybe there is a 12V conversion and another 5V conversion...Or - maybe the Sevcon power supply has 2 outputs...12V and 5V and the 12V is bad...

Calling dealer now, unless anyone has ideas.

Where is this DC-DC converter on a 2015 FX 5.7?
Thanks!

Hi there, Similar problem - BUT - have a 2015FX and the 12V system only works when temp is above 70F in the garage. Then, upon startup, all 12V items (headlights, indicator, horn and ABS) all work fine. But, if the nighttime temp goes cold, and the garage temp is 60F or less, then the 12V stuff doesn't turn on. Could this still be a fuse, or something else?

Thx,
Phil

Hi there, I have a 2015FX and the 12V system only works when temp is above 70F in the garage. When it's warm, upon startup, all 12V items (headlights, indicator, horn and ABS) all work fine. But, if the nighttime temp goes cold, and the garage temp is ~60F or less, then the 12V stuff doesn't turn on. (Interestingly, the dashboard display always works) So something is intermittent with the 12VDC device circuit.

Any ideas, anyone? What kind of fuses are used in this thing, or are they solid state relays which control the 12V? How is the 12V created? Is it a DC-DC converter off the battery voltage?
Can anyone point me in the right direction?

Thanks,
