Smile Monitoring Help

I am using the SG II and am getting a value of 10.5 for FLP during start....it takes a few minutes after start to climb above 12.0.

FMP is up at 48.0

Is the FLP value normal?

Thanks

Been reading this forum for 90 days! If I asked a stupid question, please direct me to a thread that answers my question! Is an FLP value of 10.5 a cause for concern?????????

Thank you!!!!

FICM Logic Power should be the same as Battery Power. If your getting 10.5v, you might want to get your batteries load tested.

Thank you For the reply! I Have two brand new batteries. I have read the monitoring threads, and 10.5 is the bottom of the normal range... Should I be considering a FICM rebuild? The threads i have read address low FMP as a reason to rebuild/ replace the FICM, but I haven't seen if low FLP is a cause for concern, or what if any action should be taken....thank you...

Just so you know, here are the ranges for FICM LP:

FICM_LPWR
Key on Engine off=12.0
Low Idle=13.5
High Idle=13.5
Operating Range=10.5 - 15.5 VOLTS

Test when engine is at operating range, meaning drive until engine is up to 190* ECT AND EOT at above ECT.

High idle in this test is 2500 RPM

These are Ford's specs.

Give it a shot, and come on back and share what you have found.

As for FICM specs:

FICM_MPWR
Key on Engine Off=47
Low Idle=47.5
High Idle=47.5
Operating Range=40 - 52 VOLTS
^^This is from Ford's specs, but we have found 40v is way too low.

FICM_VPWR
Key on Engine off=12.0
Low Idle=14.0
High Idle=14.0
Operating Range=10.5 - 15.5 VOLTS

And for this^^^ FICM Vehicle Power (Volts) (Should be 12 Volts, should not drop below 10.25 for more than 60 seconds, or 9.0 for 4 seconds. TSB 09-24-03)

Check your Grounds from the battery. Make sure they are clean.

This is just me, I make sure when I park for the night, everything in the truck is turned off. A/C, radio, fan, everything I can, is off. So, when I start in the morning I give the batteries an opportunity to be successful.

I, in the last couple days, have noticed a lower "than I like" voltage reading from my 2 and a half year old batteries. I just might be getting new batteries in the near future.

My Scangauge II volt readings this morning, the first time I might add, dropped during cranking to 9.8V. Scared me to death. I, in May, just had my FICM repaired. I will not do that again!!!

My ScanGauge II is 3-4 weeks old now. It only shows me voltages to the nearest 0.5 v... How do I get it to show to the nearest tenth like yours?

Thank you for the help.

I did not know that the engine had to be at operating temp....does that apply to all of the voltage tests you posted above?

If these are all checked at operating temps, I think I am OK. Though my FLP is only 10.5 during cold starts...it does climb up to 12-13 within a few minutes.

So, if any of the three FICM values are out of range with good batteries, should I be replacing the FICM?

Check the Main power of the FICM when cold and hot. My FICM, when cold, would on Key On Engine Off, start at 39v and with in 10 seconds read 48v. Then, the rest of the day would read good. Eventually it would start at 30v, then go to 48v. I have since had it fixed.

Some have had their FICMs lose volts on WOT. After engine was warmed up. Some have seen a drop into the low 20s during these runs. FICMs are a peculiar things.

First, make sure batteries and alternator are working properly. Load test batteries individually, and have alternator checked. Here is a FAQ page from FICMrepair.com

FICM Repair.com - Your Source for FICM Repair

I hope I didn't confuse anyone about my "volts" of 9.8v. That reading was not on a FICM, it was on the "volts gauge".

Here is what my FICM was doing:


[quote...swilson143]My ScanGauge II is 3-4 weeks old now. It only shows me voltages to the nearest 0.5 v... How do I get it to show to the nearest tenth like yours?[/quote]

I am not sure why mine would and yours wouldn't. Mine goes up or down in tenths. Now, we are talking "volts", which is a stock gauge and not FICM gauges, which are Xgauges. And the FICM's do only go up by 0.5v. (I never really thought about getting them to read in tenths)

Here is a short video of my "volts" going by tenths:


Mine is a couple years old, maybe they changed something during an update that did this.

Thank you for the input Amdriven

I will give those parameters a closer look over the weekend and report back.
