does anyone know what the readouts are? there is one that seys deg c 090. my qestion is what the temp read out is for trans or oil temp.

this is for a 2002 f150 w/ a 5.4.

the self test is when you hold the trip reset button down and turn the int. on.

also if any one has any more info on this matter that would be great.

 

Huh, never heard of that.

 

That is water temp in degrees celceius from what I understand.

 

I would assume its for the engine temp, meaning coolant temp, not trans or engine oil temp.

see the link below, I would assume it would be the same, or almost the same, between the F series and the Mustang:

What you are referring to is called Hec code readouts.
They are all engine related items only, nothing for any other parts that have no inputs to the dash.
The readouts can be in decimal, octal or hexadecimal codes depending on what the readout is for.
The readouts are engine RPM, fuel tank level sender operation, engine temperature, charge/battery voltage range, voltage condition in start and run ignition positions.
Fault codes for the fuel pump system, PATS, ECU, communication faults between Pats and PCM, oil pressure switch failure and supporting data and to tell when the dash it'self may have an issue.
The codes are displayed on the odometer readout or as B codes in lue of P codes.
When there are PATS issues, the dash will often display the fault code being detected.
You must have all this data to interpet the meanings of what you see.
.
As far as the trans temperature goes, the sensor on the trans valve body will not allow OD to be upshifted until a min temp has been reached in the 95 degree range +/- and will signal the PCM for a code if the temp goes out of limits as set in the PCM program.

A temprature gage monitoring the output of the converter will generally run in the 150 degree range +/- under light loading in OD and run a bit higher in hot ambient outside temps over 90 degrees.
In lower gears and a lot of stop and go, hot temps will run the output temp up well over 160 due to not being in lockup.
Hope this gives you some idea of what the dash can display.
Good luck.

 

Google "HEC Dealer Test Mode"

HEC= Hybrid Electronics Cluster

 

Here is the guts of the text from the URL above ( so the next member can find it quick )

Activating Test Mode

To enter the HEC Dealer test mode, depress and hold the instrument cluster SELECT/RESET button, turn the ignition switch to the RUN position, and then continue pressing the SELECT/RESET button (5 seconds) until tESt is displayed in the odometer. The SELECT/RESET button must be released within 3 seconds of the odometer tESt display 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 stored continuous DTCs before proceeding to the next step.

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.

All segments illuminated
lluminates all odometer segments. If any odometer segment is inoperative INSTALL a new instrument cluster.

bulb
lluminates all micro-controlled indicators and LEDs. Install a new indicator or LED as necessary.

r
eturns to normal operation of all micro-controlled indicators and LEDs and displays hexadecimal value for ROM level. (used when requesting assistance from the hotline). If alternating flashes for FAIL and ROM level are displayed, INSTALL a new instrument cluster.

EE
Displays the hexadecimal value for EE level (used when requesting assistance from hotline). If alternating flashes of FAIL and EE level are displayed replace instrument cluster.

dt
Displays hexadecimal coding of final manufacturing test date (used when requesting assistance from hotline).

dtc
Displays continuous DTC's in hexadecimal format. 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 in not received. If input is invalid for one second or more, or if speed is 0.

m
Displays the metric speed data in kph. Speedometer will indicate present speed within tolerances. Display will show 0 if input in not received. If input 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 within tolerances. Tachometer will indicate present RPM. Display will show 0 if input is no received, if input received is invalid for one second or more, or if engine RPM is 0.

FUEL
Displays the code (0-255) for the fuel sender input to the HEC. The fuel gauge will display a filtered fuel level value. This filter will keep the pointer from moving suddenly or erratically.
255 open send +/- 0
232 full stop +/- 0
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 (0-250) for the oil pressure switch input to the HEC. Oil pressure gauge will indicate present oil pressure. Normal oil pressure (greater than 6psi) will display a value between 000 and 176. A low oil pressure or an inoperative engine oil pressure switch (less than 6 psi) will display a value greater than 176.

dEGC
Display of engine temperature in Degrees C input from cylinder head temperature sensor.
49 C "C" mark
60 C Normal band start
120 C Normal band end
-40 C No SCP message for 5 seconds

bAtt
Displays the code (0-255) for the battery voltage input to the HEC. Battery voltage gauge will indicate present battery voltage.
93-102 6.2-9.1 volts, low voltage
115-124 8.5-10.7 volts, Normal band start
215-225 15.8-18 volts, Norm band end
230-241 16.9-19.1 volts, high voltage

rhEo
Displays the present decimal rheostat dimming input, 0-255 (used when requesting assistance from the hotline)

rhi
not used

rhS
not used

rho
not used

Cr
Displays the current RUN/START sense input. Display will show -h for high input with the ignition switch in the START position and -L for low input with the ignition switch in the RUN position.

PA-PE7
not used

GAGE
Repeats the display cycle

In the test mode, I read that the rpm gauges would reset "How do you reset the rpm gauge on a f150?
Press and hold the reset button. While holding the reset button, turn on the ignition key but do not start the car. At the bottom of the dashboard, you should see a sign that says "sweep gauges" or watch as the gauges begin resetting to the correct positions .Sep 7, 2022". Mine doesn't. When the truck is idle, the rpm shows below 0. Using the test mode when the engine is idle, it shows the true rpm in digital form. Why doesn't that work?

 

If the tach doesn't sweep during the gage test and displays zero RPMs while the engine is running, it's busted.

 

It does sweep when the engine is idle or off. And it does display the correct rpm when idle in the test mode. But in normal conditions, the rpm shows below zero when idle. So, IDK
