Need to find out the uses of the differnt modes on the odometer on my 99 f-1-fity there is some good info possibly going to waste cause I-aint-no-guru.. any links or tips? huh guys(and gals)

 

Hi tommysquyres and welcome to FTE

Do you mean something like this?

To enter the HEC ( Hybrid Electronic Cluster) Dealer Test Mode, depress and hold the instrument cluster SELECT/RESET button and then turn the ignition switch to the RUN position. Continue pressing the SELECT/RESET button (five seconds) until tESt is displayed in the odometer. The SELECT/RESET button must be released within three seconds of the odometer displaying tESt to begin the dealer test mode. Depress the SELECT/RESET button to advance through the following steps until dtc is displayed. Depressing the SELECT/RESET button will display any continuous DTCs stored before proceeding to the next step.



Odometer Display Description

GAGE : Activates gauge sweep of all gauges, then displays present gauge values. Also carries out the checksum tests on ROM and EE. If the gauge sweep is inoperative, INSTALL a new instrument cluster; REFER to Instrument Cluster .

All segments illuminated : Illuminates all odometer segments. If any odometer segment is inoperative, INSTALL a new instrument cluster; REFER to Instrument Cluster .

bulb : Illuminates all micro-controlled lamps and LEDs (low oil pressure/high coolant temperature, low fuel, service engine soon, brake, low range). INSTALL a new bulb or LED as necessary.

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). If alternating flashes of FAIL and ROM level are displayed, INSTALL a new instrument cluster; refer to Instrument Cluster .

EE : Displays hexadecimal value for EE level (used when requesting assistance from the hotline). If alternating flashes of FAIL and EE level are displayed, INSTALL a new instrument cluster; refer to Instrument Cluster .

dt : Displays hexadecimal coding of final manufacturing test date (used when requesting assistance from the hotline).
dtc : Displays continuous DTCs. Pressing the SELECT/RESET button will display any DTCs stored before proceeding to the next step.

enG : Displays the English speed in mph. Speedometer will indicate present speed within tolerances. Display will show 0 if input is not received, if input received is invalid for one second or more, or if speed is 0.

m : Displays the English speed data (mph) received from the PCM via the SCP network. Displays the metric speed in kph. Speedometer will indicate present speed within tolerances. Display will show 0 if input is not received, if input received is invalid for one second or more, or if speed is 0.

tAc : Displays the tachometer data received from the PCM via the SCP network. Tachometer will indicate present speed within tolerances. Display will show 0 if input is not received, if input received is invalid for one second or more, or if engine rpm is 0.

FUEL : Displays the actual A/D fuel level. The fuel gauge will display a filtered fuel level value. This filter will keep the pointer from moving suddenly or erratically. If the value displayed is between 0 and 20, the circuit is shorted. GO to Pinpoint Test D .
255=open send +/-0
232=Full stop +/-10
215=Full mark +/-10
178=3/4 mark +/-8
138=1/2 mark +/-7
93=1/4 mark +/-5
41=E mark +/-4
54="LOW FUEL" (0-59)
0-18=short (0-20 max.)

OIL : Displays the code (0-255) for the oil pressure switch input to the HEC. Displays the oil pressure reading input to the HEC. Oil pressure gauge will indicate present oil pressure. Normal oil pressure (greater than 6 psi) will display a value between 000 and 176. A low oil pressure (less than 6 psi) or an inoperative engine oil pressure switch will display a value greater than 176.

dEGC : Display of engine temperature in Degrees C input from cylinder head temperature sensor. If the value displayed is -40C, the SCP message for engine temperature has not been received for more than 5 seconds. GO to Pinpoint Test E .
49 C="C" mark.
60 C=Normal band start.
120 C=Normal band end.
119 C=Temperature warning indicator ON.
"-40" C=No SCP Message for 5 sec.

br : Displays the brake fluid level input to the HEC.

bAtt : Displays the code (0-255) battery voltage input to the HEC. Battery voltage gauge will indicate present battery voltage.
93-102=6.9-9.1 volts (Low voltage)
115-124=8.5-10.7 volts (Norm band start)
215-225=15.8-18 volts (Norm band end)
230-241=16.9-19.1 volts (High voltage)

rhEo : Displays the present hexadecimal value for the instrument cluster backlighting pulse width modulated (PWM) input to the HEC (used when requesting assistance from the hotline).

rhi
rhS
rho : PWM input duty cycle.

SCP hexadecimal dimming step (used when requesting assistance from the hotline).
Output driver counts in hexadecimal format (used when requesting assistance from the hotline).

Cr : Displays the present RUN/START sense input. Display will show -L with the ignition switch in the START position and -h with the ignition switch in the RUN position.

ALtF a : Displays 8-bit hexadecimal value for alternate fuel level. Display will show a value between OO and FF if the message is received.

PA-PE7 : Not used.

GAGE : Repeats test display cycle.

a : Refer to 413-01B (F250 only).

Turn the ignition switch to the OFF position or press and hold the SELECT/RESET button for three or more seconds and release to exit HEC Dealer Test Mode. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue diagnostics.

 

:-staun After I decipher this mumbo I'll surely put some to use...
Now I know who to ask for TECH info! thanks a million man.

 

Wow Dave, that's something else. Is this a trick digital instrument panel, or just the odometer display on my analog panel that does all of this?

Seems like an instrument panel diagnosis routine - did I miss anything that would be interesting if my gauges, lights etc. were all working great?

 

I think all the 97 and up trucks will do the same tests. It's just for diagnosing the instrument cluster if there is something wrong with it.

 

What about pre 97? I have a '95, does it work on it too?

 

On a 1995 truck the speedo is programmable for different tire sizes etc but I think that's about it.....if I remember correctly
Steve83 would probably know.
