OK... HERE WE GO! 1. Put the key in the ignition, but don't turn it. Push and hold the trip / reset counter button. Don't release it. 2. Next turn the key to the accessory on position. NOT starting your stang, but just to the first click. Leave the key there. 3. Look at your display while you are holding down the button. When you see it say "test" (like shown in the pic), then LET GO the button. You have only a few seconds to do this. 4. What will happen next is all your analog needles will "sweep" to their max positions and then drop back to normal. The digital readout will say "GAGE" like shown. 5. Push the button once and the next diagnostic is all the segments in the digital display will show up lit. Like the pic shows. 6. Push the button again and the readout will say "bulb" and light up all the bulbs like the batt, traction control and other cluster bulbs. Neat huh ?..  7. Push the button again and the ROM version is displayed. 8. Push the button again and you get the EE level. Part of the id. 9. Push it again and you see the hex value for the manufacturing test date. 10. Push it again and you will get any diagnistoc trouble codes or DTC's (if any). See table below for a list of codes. This code is for an oil pressure switch failure (example). 11. THE COOL PARTS START HERE. push it again and you will see "eng" followed by your speed in miles per hour. We were standing still but if we were moving, we could get a digital speedo reading in real time. 12. Push it again and you will see an "M" followed by your METRIC speed reading. 13. Push it again and you will see a "tac" followed by your tachometer numbers. All updated in real time. The engine was off here so it was 0000. CLICK HERE for a video 126k Mpeg of the digital tach in action. (recorded from our Mustangworld project 00 stang) 14. Push it again and you see your fuel level, see chart below for what the numbers mean. 15. Push it again and you see your oil pressure. The engine was off so ours read 255. 16. Push it again and you will see your engine temperature "deg" see chart below for what the numbers mean. 17. Push it again and the battery voltage input to your cluster is shown (current battery level) 0 - 255. See chart below for normal settings. 18. Push the button again for the RH codes (there are a few screens of them and they flash). 19. Eventually you will end up at the Cr code, this shows the current RUN/START here it shows "-h" meaning in the key was in the start position. 20. You will make it to the PE codes then back to the "GAGE" and the cycle starts all over again. TO EXIT the diagnostic mode, press and hold the trip meter for 5 seconds or until your odometer is displayed again. You can also just remove your key and it will return to normal. To see your digital speed / tach, etc.. as your stang drives All you do is once in this diagnostic test mode, simply start your stang and the display will revert to this mode again and you can scroll through until the digital speedo is showing and see your speed digitally.

Wow thanks for this! I cant believe that with all these countless Ford mechanics helping every one of us out here with there yt vids, I don't believe i have ever come across a video that exposes this awesome gem. Once again, thank you for taking the time in doing this video👏

4l34 10849 oco2 is the casting number for the instrument cluster in that truck. That way the technician could retrieve the part number for the cluster without pulling it out if they needed to order one, or if original part number needed for some reason or another.

Hey Man: I'm a ford truck owner and I never knew this feature was in it. A big thank you Brother!

2 years later and this was cool to learn. Much thanks.

1. The 4L34 10849 is the part number for the cluster 2. Second set of numbers is the calibration 3. Ign b is the position the is the position of the key in the ignition 4. Dtcs shown are cluster related, will show dtcs if there is faults within the gauge cluster not the pcm (engine computer)

Very cool, I've been driving these since 2007 and never new that. Thanks for sharing!

Sweet. Just bought a 2004 F 150 4X4 and I had no idea this little feature was there. Gonna try it tomorrow, thanks

Thanks you for sharing this had a 99 and just bought a 2002 this info is vey helpful. Being a female I try to do a lot of my easy work myself to avoid being ripped off. Thanks again for sharing

Love that my 2007 ford expedition has this feature i love using the battery display helps having a subwoofer setup 👍👍👍

Thank you for this video. My 2003 f350 has a code and this has helped find my problem!! Didn’t know about this test so thank you again!!!

I've owned my truck for like right years and NEVER knew this. Greatly appreciated good sr!!!

GK7 DIY Great tip for Ford owners! Thanks. One of the comments on your page listed the steps for doing this. I took your list and added the comments to put them on a page that I put in a notebook for my truck.

Thanks man.i just got a high miles 06 f150 and this is a helpful self diagnosis and sensor awareness option that I didn't even know about.

Great video! I have a 2007 and didn’t know about feature. Thanks buddy !

I’ve had my ‘21 for a little over a year now and never tried this but had it in the shop 4x. This may actually help me so thank you, whether it works or not!!

I wish I would have seen this video right after you posted it. IT is extremEly useful to me with my motorhome on a Ford e450 CHASSIS.

Nice, thank you!

Thanks buddy I had no idea.thats something I do often an never wanted to buy a scanner so now I can do it myself
