Hi All
installed my Scangauge ll yesterday, pretty easy to set up, I have a dozen X-Gauges programed now.

looks like I need a new FICM as my scangauge is reporting high 30's until it warms up then it reads 46-48v.

47v key on engine not started
37-42v engine started cold
46-48v engine warm.

I cant read it during the engine cranking cycle.

I just set up the following X-gauge "SYC"
FICM signals for Camshaft and Crankshaft positions are in sync
1 = in sync, 0 = not in sync


the gauge is reading "0" so it looks like I'm out of sync.

my questions is, when I update / rebuild / repair the FICM will this issue correct itself, or should I be looking in another direction?

If FICM voltage is dropping the FICM needs to be replaced or repaired. The voltage should hold steady at 47-48V. How awesome is the ScanGauge... For less than 200 bucks you get a whole lot of data!!! Plus you can gauge fuel MPG as well. And pull and clear codes... I love mine!!

Thanks Elvis
I haven't had it for 24 hours yet but the bang for your buck is the best on the market. I've been researching them for a while now. there are more capable units, but the cost was out of reach for me.

I have plans to repair my FICM, that's a given, the questions is the SYNC issue.
will the camshaft and crankshaft sync up once the FICM is repaired.

i have been told that the low voltage when cold isthe resisters that have come unsoldered. Mine does the same thing and I know i did not do the best job on these small resisters.

I was in the 20's pulling hard a no starting issue, and far from 48V when I resoldered the unit but one resister gave me trouble and it is at 35's when cold when the injector heating is going on when cod.

Which of these Sync's are you using? Each will show being in "Sync" with PCM. (If I'm understanding things correctly.

Posted by "Fordmasterdieseltech"

"ficm sync and pcm sync are the combination of signals sent to the pcm from the crank and camshaft position sensors. from there the pcm sends the crank and cam signals to the ficm, where the ficm determines when and what injector to fire."

(note the RXD's are different)

Camshaft & Crankshaft Sync (1 = in sync, 0 = not in sync)

TXD: 07E02209CD

RXF: 0462050906CD

RXD: 3000 (3001 alternate)

MTH: 000100010000

NAM: SYC

FICM Sync
TXD: 07E02209CD
RXF: 0462050906CD
RXD: 3601
MTH: 000100010000
NAM: FSN (1 = in sync, 0 = not in sync)

Update:
FICM removed, repaired, installed

48.5 Key on
48.0 Cold
48.0 warm

one resistor had a cold solder joint.

also installed the blue spring kit. install was not so bad. only a half a dozen curse words

she's running like a champ now.

all I need now are some new fuel and air filters, and I should be ready for the cold weather in a few months.

47 days till opener....

Thanks for the link / advice
I just ordered them should be here in a few days.

now off for a primary fuel filter install tutorial, and list of tools needed.
probably another specialty socket involved, something no one has.

What ever you do, DO NOT USE THE 1/2" DRIVE SQUARE in the upper fuel filter. The dang cap can and will crack! (By the way, they have designed a new lower fuel filter, so don't be surprised if the one you pull out doesn't look like the new one)

15/16" socket for upper.

36mm for lower fuel cap.

Drain water in fuel plug first, Then an extension to make it to the cap. While you are there, you might want to install a Fumoto valve on the water drain plug. Those stock ones tend to strip. I'll be installing mine shortly.

Fumoto valve.
Ford part number: 6E7Z-9C082-A
International part number: 2589259C91

Here is a good guide to changing fuel filters.

36MM socket.... I knew it would be something I didn't have.

thanks for the info on the Fumoto.


Update:
"So, you fix your FICM, your "Sync" between FICM and PCM should be resolved."

My Sync is still at 0 after the fix. I'm not sure how upset I should be about this.

That's just weird. I sure thought the sync would come back to 1 after the fix.

Is your truck setting a CEL?

Here is something to try as an Xgauge.

DTC Count (Diagnostic Trouble Code Count)

TXD: 07E0220200

RXF: 046205020600

RXD: 3008

MTH: 000100010000

NAM: DTC


For some reason, the Scangauge wont pick up some "soft" codes. But, I have seen this gauge in my truck count DTC's. But yet not set the CEL. If you find this is counting, you might want to find another scanner to see what code it is counting.
