Instrument Cluster Self-Diagnostic Mode

To enter the instrument cluster self-diagnostic mode, press 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 self-diagnostic mode. Press the SELECT/RESET button to advance through the following steps until dtc is displayed. Pressing the SELECT/RESET button displays any stored continuous DTCs before proceeding to the next step.

ODOMETER DISPLAY DESCRIPTION CHART

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.
All segments illuminated	Illuminates all odometer segments.
bulb	Illuminates all micro-controlled indicators and LEDs. Install a new indicator or LED as necessary.
r	Returns to normal operation of all micro-controlled indicators and LEDs and displays hexadecimal value for ROM level (used when requesting assistance from Ford).
EE	Displays hexadecimal value for EE level (used when requesting assistance from the hotline).
dt	Displays hexadecimal coding of final manufacturing test date (used when requesting assistance from the hotline).
dtc	Displays continuous DTCs in hexadecimal format. Pressing the SELECT/RESET button displays any DTCs stored before proceeding to the next step.
enG	Displays the English speed in mph. Speedometer indicates present speed within tolerances. Display shows 0 if input is not received, if input received is invalid for 1 second or more, or if speed is 0.
m	Displays the metric speed data (km/h). Speedometer indicates present speed within tolerances. Display shows 0 if input is not received, if input received is invalid for 1 second or more, or if speed is 0.
tAc	Displays the tachometer data received from the PCM via the SCP network within tolerances. Tachometer indicates present rpm. Display shows 0 if input is not received, if input received is invalid for 1 second or more, or if engine rpm is 0.
FUEL	Displays the code (0-255) for the fuel sender input to the instrument cluster. The fuel gauge displays a filtered fuel level value. This filter keeps the pointer from moving suddenly or erratically.
FUEL	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 instrument cluster. Oil pressure gauge indicates present oil pressure. Normal oil pressure (greater than 6 psi) displays a value between 000 and 176. A low oil pressure or an inoperative engine oil pressure switch (less than 6 psi) displays a value greater than 176.
dEGC	Display of engine temperature in degrees C input from cylinder head temperature sensor.
dEGC	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 instrument cluster. Battery voltage gauge indicates present battery voltage.
bAtt	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 decimal rheostat dimming input, 0-255 (used when requesting assistance from the hotline).
rhi rhS rho	Not used.
Cr	Displays the present RUN/START sense input. Displays -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 test display cycle.

To exit the instrument cluster self-diagnostic mode, turn the ignition switch to the OFF position or press and hold the SELECT/RESET button for 3 or more seconds and release.
