I have an EDGE CTS Monitor on my '04' Ex. with the early 6.0L that reads the FICM voltage. My question is, "Is this reading, the CTS Monitor reading, as accurate as the one I would get if I went through FICM Voltage check procedure in the Tech. Manual on this site?"
Currently when I turn the ignition on, and before I start the motor, it reads 47.5 to 48.5 volts. Based on the info. on this site that is within specs.
Just wondering about the accuracy.
Thanks for any thoughts/input here.

 

I have the CTS as well. I also just got my FICM repaired by Ed. Prior to the repair, my FICM voltage dropped as low as 26 when cranking. After the repair, it never goes below 47.5. I'm no expert by any means, but it's accurate enough for me

 

Can't speak to accuracy; but mine reads from 47.5-48.5.

 

My CTS reads 47.5-48.5, good enough for government work. A half volt isn't the death knell for the FICM, when it drops below 45V is when it's time to get it fixed.

 

How do you guys get FICM reading on a CTS? I bought a CTS a year ago and dont have it

 

I think you have to update you "Fusion" software and then up date your reader.
I bought mine two years ago and updated my reader last fall and I can read the FICM voltage

Just an FYI

 

Glad to have taken care of you, TruckNorris!

The reading on the CTS is accurate and yet another reason to own that gauge. It's just awesome.

 

How do you update your reader? I just updated the fusion software on edges website and uploaded it to my cts

 

That's pretty much all you do, then you should have the ability to select FICMV on your CTS

 

This is either the latest or nearly latest firmware verison from Edge:
Firmware Version: 3100155733
Calibration Version: 350102565
Application Version: 5010
FPGA Version: 1922682447

If you have this then you should have FICM V as a PID now.

 

I got my answer.
Thanks to all for your input and especially Ed as he is surely an expert here.

 

Yup, i have ficm voltage! Thanks guys! Its 47.0-48.5 all the time even when cold

 

Happy to be of service!
