Dealer Test Mode Displays

  1. All Segments Illuminated

    Illuminates all odometer segments. If any odometer segment is inoperative, replace instrument cluster. See INSTRUMENT CLUSTER/MODULE (ICM)  under REMOVAL & INSTALLATION.

  2. "GAGE"

    Activates gauge sweep of all gauges, then displays present gauge values. Also carries out checksum tests on ROM and EE. If gauge sweep is inoperative, replace instrument cluster. See INSTRUMENT CLUSTER/MODULE (ICM)  under REMOVAL & INSTALLATION.

  3. "bulb"

    Illuminates all micro-controlled lamps and LEDs. If any bulb is inoperative, perform appropriate tests. See SYMPTOM INDEX  table under SYSTEM TESTS.

  4. "r"

    All micro-controlled lamps and LEDs return to normal operation. If alternating flashes of FAIL and ROM level are displayed, replace instrument cluster. See INSTRUMENT CLUSTER/MODULE (ICM)  under REMOVAL & INSTALLATION.

  5. "EE"

    If alternating flashes of FAIL and EE level are displayed, replace instrument cluster. See INSTRUMENT CLUSTER/MODULE (ICM)  under REMOVAL & INSTALLATION.

  6. "dt"

    Displays final manufacturing test date.

  7. "dtc"

    Displays instrument cluster DTCs. If any DTC are retrieved, perform appropriate test in accordance with DTCs retrieved. See INSTRUMENT CLUSTER DTC INDEX  table under RETRIEVING CODES (SCAN TOOL).

  8. "cFG0"

    Displays software coding.

  9. "cFG1"

    Displays software coding.

  10. "cFG2"

    Displays software coding.

  11. "cFG3"

    Displays software coding.

  12. "SPd xxx.x mi"

    Displays speed in MPH. Speedometer will indicate present speed within tolerance. If display shows 0 and vehicle speed is more than 5MPH, input is not received, or input is invalid for one second or more. Perform TEST G: SPEEDOMETER INOPERATIVE  under SYSTEM TESTS.

  13. "SPd xxx.x kmi"

    Displays speed in KM/H. Speedometer will indicate present speed within tolerance. If display shows 0 and vehicle speed is more than 10KM/H, input is not received, or input is invalid for one second or more. Perform TEST G: SPEEDOMETER INOPERATIVE  under SYSTEM TESTS.

  14. "tAc xxxx"

    Displays tachometer data. Present RPM within tolerance. If display shows 0 and engine is running, if input is not received, or input received is invalid for one second or more. Perform TEST T: TACHOMETER INOPERATIVE  under SYSTEM TESTS.

  15. "FuEL"

    Fuel gauge will display a filtered fuel level value. See FUEL LEVEL VALUE  table. If value displayed is 0-20 circuit is shorted. Perform TEST D: INCORRECT FUEL GAUGE INDICATION  under SYSTEM TESTS.

    Short Circuit (1) (2) 0-20
    (1) Circuit condition.
    (2) Perform TEST D: INCORRECT FUEL GAUGE INDICATION  under SYSTEM TESTS.

  16. "dEGC"

    Displays engine temperature (°C). See TEMPERATURE VALUE  table. If value displayed is -40C, engine temperature has not been received for more than 5 seconds. Perform TEST E: INCORRECT TEMPERATURE GAUGE INDICATION  under SYSTEM TESTS.
    TEMPERATURE VALUE

    Temperature Displayed Value
    Cold Mark 49C
    Normal Band Start 60C
    Normal Band End 120C
    No Message for 5 seconds (1) -40C
    (1) Perform TEST E: INCORRECT TEMPERATURE GAUGE INDICATION  under SYSTEM TESTS.

  17. "bAtt"

    Displays battery voltage input to HEC. Voltage gauge indicates present battery voltage. See BATTERY VOLTAGE  table.
    BATTERY VOLTAGE

    Display Code Voltage
    93-102 6.9-9.1 (Low Voltage)
    115-124 8.5-10.7 (Normal Band Start)
