04+ owners Go out to your trucks put your key in the ignition(leave in off postion).Hold down the reset on your trip ommeter while holding down turn your key on.Press the reset button to cycle and enjoy.

 

and what happens?

Press control + alt + delete and watch what happens..

 

Yeah I will wait to hear what happens before I do that lol.

 

I swear nothing bad let's you pull up digital speedo.tach.engin temp.battey voltage dtc's and a bunch of other test

 

Learned off of focus board tryed it and it works on our trucks to

 

will it show any trouble codes?

 

Can you leave it once you pull up certain readouts?

 

Yeap

 

Ohhhhhh shiiiit. 04+ have on board read outs and didn't even know it.

 

hot damn! Sweet, I have been looking for one of these quick tests for my rig. I know in newer dodge rams you cycle the ignition key 3 times as fast as you can and will give you tons of info in the dash display. Always wondered if out fords had a similar test. Interesting!

 

Good find dooder!

 

After I finish eating I will have to try it out.

 

Its bad *** I don't know what half of the test are but we have some smart peeps I'm sure we will figure it out.

 

your not supposed to know about that unless your a Ford certified Tech.
heres some stuff from my old ford book about what each thing says.

GAGE - Carries out gauge sweep of all gauges, then displays the present gauge values. Also carries out the check sum test on ROM and EEPROM.

All segments illuminated.
Illuminates all odometer segments.

bulb
Illuminates all micro-controlled lamps and LEDs.

r ####
Returns to normal operation of all micro-controlled lamps and LEDs and displays hexadecimal value for ROM level (used when requesting assistance from the hotline).

nr####
Displays hexidecimal ROM level and type as stored in non-volatile memory (NVM).

EE ##
Displays hexadecimal value for EE level (used when requesting assistance from the hotline).

dt ####
Displays hexadecimal code for the final manufacturing date.

###C
Gas engines display last temperature gauge input value from SCP, temperature gauge will indicate present temperature. Diesel engine displays present temperature analog/digital input in decimal as a ratio, temperature gauge will indicate present temperature.

dtc ####
Displays a 16 bit DTC in hexidecimal format. DTCs displayed are those detected in continuous operation not during self-test.

EnG
Displays English speed value being input, speedometer will indicate present speed.

m
Displays metric speed value being input, speedometer will indicate present speed.
tAc Displays the tachometer value being input to the instrument cluster. Tachometer will indicate present rpm.

FUEL
Displays the present analog/digital fuel level being input to the instrument cluster as a ratio.

OIL
Displays the last analog/digital reading of the oil pressure switch contact resistance, oil gauge will indicate present level.

br
Displays the brake fluid level in an analog/digital ratio value.

bAt ##.#
Displays present battery analog/digital voltage.

rhEo
Displays present hexadecimal pulse width modulation (PWM) dimming input.

rhi, rhS, rho
Alternating 1 second display of pulse width modulation (PWM) input duty cycle, SCP hexidecimal dimming step, output driver counts in hexadecimal.

Cr
RUN/START sense circuit check.

PA, Pb, PC, and Pd
Displays 8-bit hexadecimal value for the Port A, B, C, and D readings (used when requesting information from the hotline).

PE0-PE7
Displays 8-bit hexadecimal value for the Port E0-Port E7 in analog/digital readings

 

Close enough im a Gm Jorneyman Tech and a Pizza boy

 

cool find, just wish it would override the speed limiter & boost performance 2 lol

 

*cough*https://www.ranger-forums.com/showth...ster+test+mode *cough*

 

reupload the vid because it didn't work in the old thread

 

Its a pretty cool trick, the F-150s have been able to do that since 99!

Wayne

 

Man i was hoping this would give my truck like 50 more hp....haha jk. cool trick though!

 

still couldn't get it to work on my 2006

 

Its funny mine is showing a dtc 0-9868 never heard of a 0 prefix heard of p-xxxx b-xxxx c-xxxx and u-xxxx

 

older fords did this. my 85 w/a 5.0L efi would blink the check engine light in a sequence so you could take that number 5 blinks, pause 2 blinks was 52.

 

Thats cause its obd1 thats how you find out dtcs on obd1 vehicles
