    Instrument Cluster Dealer Test Mode

    Here ya go gents...for all that was wondering what it is and how to do it...

    Instrument Cluster Dealer Test Mode
    To enter the Instrument 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.

    All segments illuminated Illuminates all odometer segments.

    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).

    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. Pressing the SELECT/RESET button will display any DTCs stored before proceeding to the next step.

    enG Displays the 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 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.
    • 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 instrument cluster. Displays the oil pressure reading input to the instrument cluster. 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.
    • 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 instrument cluster.

    bAtt Displays the code (0-255) battery voltage input to the instrument cluster. 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 instrument cluster (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.

    PA-PE7 Not used.

    GAGE Repeats test display cycle.

    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 Instrument Cluster Dealer Test Mode. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue diagnostics.

    1. Put the key in the ignition, but don't turn it. Push and hold the trip / reset counter button. Don't release it.
    2. Next turn the key to the accessory on position. NOT starting your Vehicle, but just to the first click. Leave the key there.
    3. Look at your display while you are holding down the button. When you see it say "test", then LET GO the button. You have only a few seconds to do this.
    4. What will happen next is all your analog needles will "sweep" to their max positions and then drop back to normal. The digital readout will say "GAGE".
    5. Push the button once and the next diagnostic is all the segments in the digital display will show up lit.
    6. Push the button again and the readout will say "bulb" and light up all the bulbs like the battery, traction control and other cluster bulbs
    7. Push the button again and the ROM version is displayed.
    8. Push the button again and you get the EE level. Part of the id.
    9. Push it again and you see the hex value for the manufacturing test date.
    10. Push it again and you will get any diagnostic trouble codes or DTC's (if any). See table below for a list of codes. This code is for an oil pressure switch failure (example).
    11. THE COOL PARTS START HERE. push it again and you will see "eng" followed by your speed in miles per hour. We were standing still but if we were moving, we could get a digital speedometer reading in real time.
    12. Push it again and you will see an "M" followed by your METRIC speed reading.
    13. Push it again and you will see a "tac" followed by your tachometer numbers.
    14. Push it again and you see your fuel level, see chart below for what the numbers mean.
    15. Push it again and you see your oil pressure. The engine was off so ours read 255.
    16. Push it again and you will see your engine temperature "deg" see chart below for what the numbers mean.
    17. Push it again and the battery voltage input to your cluster is shown (current battery level) 0 - 255. See chart below for normal settings.
    18. Push the button again for the RH codes (there are a few screens of them and they flash).
    19. Eventually you will end up at the Cr code, this shows the current RUN/START here it shows "-h" meaning in the key was in the start position.
    20. You will make it to the PE codes then back to the "GAGE" and the cycle starts all over again. TO EXIT the diagnostic mode, press and hold the trip meter for 5 seconds or until your odometer is displayed again. You can also just remove your key and it will return to normal.

    To see your digital speed / Tach, etc.. as your Vehicle drives
    All you do is once in this diagnostic test mode, simply start your Vehicle and the display will revert to this mode again and you can scroll through until the digital speedometer is showing and see your speed digitally.

    Here are the DTC trouble codes:

    9202 Fuel sender open circuit
    9204 Fuel sender short to ground
    9213 Anti-theft number of programmed keys is below minimum
    A103 or 9232 Antenna not connected-defective transceiver
    9317 Battery Voltage high
    9318 Battery voltage low
    9342 ECU is defective
    9356 Ignition run circuit open
    9364 Ignition Start circuit open
    9600 PATS Ignition Key Transponder Signal is Not Received - Damaged Key or non-PATS Key
    9601 PATS Received Incorrect Key-Code from Ignition Key Transponder (un-programmed Encoded Ignition Key)
    9602 PATS Received Invalid Format of Key - Code From Ignition Key Transponder (Partial Key Code)
    9681 PATS Transceiver Signal is Not Received (Not Connected, Damaged, or Wiring)
    A139 PCM ID does not match between Instrument Cluster and PCM
    A141 NVM Configuration Failure (No PCM ID exchange between Instrument Cluster and PCM)
    A143 NVM memory failure
    5284 Oil Pressure Switch Failure
    D027 SCP Invalid or Missing Data for Engine RPM
    D041 SCP Invalid or missing data for Vehicle Speed
    D043 SCP Invalid or missing data for Traction Control
    D073 SCP Invalid or missing data for engine coolant
    D123 SCP Invalid or missing data for Odometer
    D147 SCP Invalid or missing data for vehicle security
    D262 Missing SCP message.

    What to do if you get a trouble code
    First off don't panic, these are not OBDII codes, call your local Ford dealer and they will give you more info. Some of these codes are NORMAL like when the dealer needs to program a new key for your Vehicle, an un-programmed key will be inserted for this procedure, you may get a code 9601, this does not mean you have a problem with your Vehicle. You can clear codes by disconnecting your battery for a while and reconnecting.
