Instrument Cluster Test and Diagnostic Mode

The Ford Focus instrument cluster can be put into a test mode, displaying diagnostic information.

Time Required:
Less than 5 Minutes

Tools Needed:

  • none required

    Procedure:

    (information found on the internet and in the 2001 Ford Cars Service manual on CD-ROM)

    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 three 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.

    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.
    All segments illuminated Illuminates all odometer segments. If any odometer segment is inoperative INSTALL a new instrument cluster.
    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 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. See index below for description of trouble codes.
    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
    rhS
    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


    To exit the HEC Dealer Test Mode, turn the ignition switch to the OFF position


    Short list of common Diagnostic Trouble Codes

    NOTE: DTC Codes are not to be used for diagnosing problems. If you believe there is a problem with your car, you should have it scanned with an OBD-II code reader. DTC Errors are typically no cause for alarm.
