Pulling codes thru odometer

[michaelwooten]

I used to be able to pull codes on my 03 XLT thru the odometer. I found the sheet that tells me how to read the codes by scrolling through with the trip reset, but I now have a 06 Lariat with the upgraded instrument cluster that does not have the little button, but instead has the three that read in order:
INFO

SETUP

RESET

Can someone send me updated instructions if this is still possible.

It was never possible to pull PCM codes through the odometer. You can get codes that relate to the instrument cluster that way.

On my 2003 I could hold down the trip button and scroll through these....

[FONT='Verdana','sans-serif']Here's the odometer function followed by a description.

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[/font]



[FONT='Verdana','sans-serif']Put your key in the ignition and leave in the off position. Hold your trip button on the speedometer to the reset position and hold there. Turn the key on but do not start yet. When all you gauges sweep release the trip button. Now you are in "digital" mode on the mileage odometer. You can start your truck and you can press the trip button to get different readings such as a digital tac. It can show you various sensor readings.

Kinda interesting.... to reset the digital stuff just turn the truck off and restart and you will back to showing the mileage.[/font]

Yes, the 03 would do that. None of that are PCM DTCs. I don't know if the later truck will do that, too.

Can anyone tell me if you can get the speedo gage reset and dig odometer test readings on a Lariat?
