Dodge Journey: Gauges

All gauges receive battery current through the CCN circuitry only when the ignition switch is in the On or Start positions. With the ignition switch in the Off position, battery current is not supplied to any gauges, and the CCN circuitry is programmed to move all of the gauge needles back to the low end of their respective scales.

Therefore, the gauges do not accurately indicate any vehicle condition unless the ignition switch is in the On or Start positions.

All of the CCN gauges are stepper motors. The gauges are diagnosed using the CCN self-diagnostic actuator test. See Diagnosis and Testing . Proper testing of the CAN data bus and the electronic data bus message inputs to the CCN that control each gauge require the use of a diagnostic scan tool. Refer to the appropriate diagnostic service information. Specific operation details for each gauge may be found elsewhere in this service information.

VACUUM-FLUORESCENT DISPLAYS

The Vacuum-Fluorescent Display (VFD) units are soldered to the CCN electronic circuit board. With the ignition switch in the Off or Accessory positions, the standard left and optional right VFD displays are activated when the driver door is opened and is deactivated when the driver door is closed. Otherwise, the display units are active when the ignition switch is in the On or Start positions, and inactive when the ignition switch is in the Off or Accessory positions.

The illumination intensity of the VFD units are controlled by the CCN circuitry based upon an input from the headlamp switch and a dimming level input received from the panel dimmer switch. The CCN synchronizes the illumination intensity of other VFD units with that of the unit in the CCN by sending electronic dimming level messages to other electronic modules in the vehicle over the CAN/LIN data bus.

The CCN VFD units have several display capabilities. The standard VFD unit displays odometer, trip odometer, engine hours, gear selector indication (PRNDL) for models with an automatic transmission, several warning or reminder indications, and various diagnostics information when certain fault conditions exist. An odometer/trip odometer switch on the CCN circuit board is used to control some of the display modes of the standard VFD.

This switch is actuated manually by depressing the odometer/trip odometer switch button, which extends through the cluster lens below the speedometer at the bottom right hand side. Actuating this switch momentarily with the ignition switch in the On position will toggle the VFD between odometer, trip odometer modes, and outside ambient temperature (for base vehicle only). Depressing the switch button for about two seconds while the VFD is in the trip odometer mode will reset the trip odometer value to zero. The optional VFD unit on the left hand side displays the Compass Mini-Trip Computer (CMTC) or the Electronic Vehicle Information Center (EVIC). The left switch button, which extends through the cluster lens below the speedometer at the bottom left hand side, is used as a STEP button for the CMTC display and for customer programmable features. The front mounted steering wheel switches are used to interface with the EVIC display.

NOTE: If the vehicles OnBoard Diagnostic (OBD) system determines that the fuel filler cap is loose, improperly installed, or damaged; a "GASCAP" message will be displayed in the Odometer/Trip Odometer. In this instance, tighten the fuel filler cap and press the odometer/trip odometer reset button once to turn the message OFF. The key must be in the Run/Start position during the reset, or you may just cycle the key. If left loose for three trips, or key cycles, a DTC will set and the MIL lamp will illuminate.

Holding the right switch depressed while turning the ignition switch from the Off position to the On position will initiate the CCN self-diagnostic actuator test. Refer toDiagnosis and Testing service information for additional details on this cluster function. The CCN microprocessor remembers which display mode is active when the ignition switch is turned to the Off position, and returns the VFD display to that mode when the ignition switch is turned On again.

The VFD unit is diagnosed using the CCN self-diagnostic actuator test. See Diagnosis and Testing . Proper testing of the CAN data bus and the electronic data bus message inputs to the CCN that control some of the VFD functions requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic service information. Specific operation details for the odometer, the trip odometer, the gear selector indicator, and the various warning and reminder indicator functions of the VFD unit may be found elsewhere in this service information. Refer to the vehicle owner's manual for further information on various readout messages.

ODOMETER/TRIP ODOMETER DISPLAY

The odometer and trip odometer give an indication to the vehicle operator of the distance the vehicle has traveled. The engine hours give an indication of the cumulative engine-ON time. This indicator is controlled by the instrument cluster circuitry based upon cluster programming and electronic messages received by the cluster from the Powertrain Control Module (PCM) or Engine Control Module (ECM) over the Controller Area Network (CAN) data bus.

The odometer/trip odometer will display some warning messages such as "DOOR" and "GATE" ajar. If equipped with the optional Electronic Vehicle Information Center (EVIC), the EVIC will display all messages except GASCAP.

The odometer, trip odometer, and engine hours information is displayed by the instrument cluster Vacuum Fluorescent Display (VFD). The VFD will display the odometer information whenever the driver side front door is opened with the ignition switch in the OFF or ACCESSORY positions, and will display the last previously selected odometer or trip odometer information when the ignition switch is turned to the ON or START positions. If your vehicle is equipped with an engine oil change indicator system, the "Change Oil" message will flash in the instrument cluster odometer for approximately 12 seconds after a single chime has sounded to indicate the next scheduled oil change interval. The instrument cluster circuitry controls the VFD and provides the following features:

  • Odometer/Trip Odometer Display Toggling - Actuating the trip odometer reset switch button momentarily with the VFD illuminated will toggle the display between the odometer and trip odometer information. Each time the VFD is illuminated with the ignition switch in the ON or START positions, the display will automatically return to the last mode previously selected (odometer or trip odometer).
  • Engine Hours Display Toggling - When the trip odometer reset switch button is pressed and held for 10 seconds with the ignition switch in the ON position and the engine not running and the engine speed message from the PCM is zero, the trip odometer information will be momentarily displayed, then the engine hours information will be displayed. The VFD must be displaying the odometer information when the trip odometer reset switch button is pressed in order to toggle to the engine hours display. The engine hours will remain displayed for about 30 seconds, until the engine speed message is greater than zero, or until the ignition switch is turned to the OFF position, whichever occurs first.
  • Trip Odometer Reset - When the trip odometer reset switch button is pressed and held for longer than about two seconds with the ignition switch in the ON or START position, the trip odometer will reset to 0.0 kilometers (miles). The VFD must be displaying the trip odometer information in order for the trip odometer information to reset.
  • GASCAP Message Display - For vehicles manufactured with a United States country code, each time the cluster receives an electronic message from the PCM indicating a monitored leak in the evaporative emissions system the cluster replaces the displayed odometer/trip odometer value with the textual message, GASCAP . This message serves as a reminder to the vehicle operator to check that the gas cap is properly installed and tightened, but could also indicate another source of air leakage in the on-board evaporative and vapor recovery emissions systems. Unless the leak is corrected, this message will latch and remain displayed during the current and each subsequent ignition cycle until the trip odometer reset button is pressed and released momentarily, which will revert the display to the odometer/trip odometer information that was last displayed for the remainder of that ignition cycle. Once the source of a leak has been corrected, the GASCAP message display will stay illuminated until the evaporative emission system runs the next leak check and passes.
  • Change Oil Indicator A change oil indicator is standard equipment on all instrument clusters built for the US market. The change oil indication appears within the fixed segment odometer Vacuum Fluorescent Display (VFD) unit on vehicles not equipped with an optional Electronic Vehicle Information Center (EVIC). On vehicles equipped with the optional EVIC, the change oil indication in the odometer VFD is electronically suppressed so as not to duplicate indications that are provided by the EVIC. The odometer VFD change oil indicator consists of cycling textual CHANGE then OIL messages, which appear in place of the odometer/trip odometer information. The EVIC change oil indicator consists of a textual Oil Change Required message that appears within the EVIC VFD
  • Communication Error - If the cluster fails to receive an electronic distance message during normal operation, it will hold and display the last data received until the ignition switch is turned to the OFF position. If the cluster does not receive a distance message within one second after the ignition switch is turned to the ON position, it will display the last distance value stored in the cluster memory. If the cluster is unable to display distance information due to an error internal to the cluster, the VFD will display Error .
  • Actuator Test - Each time the cluster is put through the actuator test, the odometer VFD will display all of its segments simultaneously, and then step through each character segment individually during the VFD portion of the test to confirm the functionality of the VFD and the cluster control circuitry.

The PCM continually monitors the vehicle speed pulse information received from the Vehicle Speed Sensor (VSS) or the Controller Anti-lock Brake (CAB) and engine speed pulse information received from the crankshaft position sensor, and then sends the proper messages to the CCN. For further diagnosis of the odometer/trip odometer or the instrument cluster circuitry that controls these functions. See Diagnosis and Testing .

For proper diagnosis of the VSS, the crankshaft position sensor, the CAB, the PCM, the CAN data bus, or the electronic communication related to odometer/trip odometer operation a diagnostic scan tool is required. Refer to the appropriate diagnostic service information.
