ELECTRONIC VEHICLE INFORMATION CENTER

The Electronic Vehicle Information Center (EVIC) data is obtained from several components on the Controller Area Network (CAN) and Local Interface Network (LIN) Data Bus circuits. The EVIC will not function properly if the bus messages from any of these components is not received. If no EVIC data is displayed or the display indicates dashes "- -", check the CAN Data Bus circuit communications, the Instrument Cluster functions, the RCM and the Totally Integrated Power Module (TIPM).

The use of a scan tool and the proper diagnostic procedures information are recommended for further testing of the EVIC, the RCM, the CAN Data Bus and Local Interface Network (LIN) Data Bus circuits.

For complete circuit diagrams, refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.

OIL CHANGE REQUIRED INDICATOR RESET

Note. A change oil indicator is standard equipment on all instrument clusters. However, on vehicles manufactured for export markets, this indicator is electronically disabled. This indicator is located within the odometer/trip odometer Liquid Crystal Display (LCD) unit. The change oil indicator consists of cycling textual CHANGE and OIL messages which appear in place of the odometer/trip odometer information in the odometer LCD unit.

This vehicle is equipped with an engine oil change indicator system. The "Oil Change Required" message will flash in the EVIC display for approximately 10 seconds after a single chime has sounded, to indicate the next scheduled oil change interval. The engine oil change indicator system is duty cycle based, which means the engine oil change interval may fluctuate, dependent upon your personal driving style.

Unless reset, this message will continue to display each time you turn the ignition switch to the ON/RUN position. To turn off the message temporarily, press and release the MENU button. To reset the oil change indicator system (after performing the scheduled maintenance), refer to the following procedure.

1. Turn the ignition switch to the ON position (Do not start the engine).
2. Fully depress the accelerator pedal, slowly, three times within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.

Note. If the indicator message illuminates when you start the vehicle, the oil change indicator system did not reset. If necessary, repeat this procedure.

Scheme 52

The Remote Compass Module (RCM) (2) is a separate stand alone module mounted to the top side of the headliner (1) at the left rear of the vehicle. The RCM can be accessed by removing both quarter trim panels and the headliner molding, then carefully lowering the rear of the headliner at the D-pillar area.

If the compass position sensor (Remote Compass Module) is inoperative and requires replacement. Refer to MODULE, COMPASS , REMOVAL .

The Compass Temperature Display system uses both non-switched and ignition switched sources of battery current so that some of its features remain operational at any time, while others may only operate with the ignition switch in the ON position. When the ignition switch is turned to the ON position, the display will return to the last function being displayed before the ignition was turned to the OFF position. Pressing and holding the instrument cluster push-button allows setting variance zones and manual calibration of the compass.

The Compass Temperature Display system is comprised of several different components that communicate over the Controller Area Network (CAN) and Local Interface Network (LIN) Data Bus circuits. If the system is inoperative a scan tool and the appropriate diagnostic information must be used to diagnose the system and related data buses.

REMOTE COMPASS MODULE

The Remote Compass Module (RCM) data is transferred on the Controller Area Network (CAN) Data Bus circuit. The RCM and Electronic Vehicle Information Center (EVIC)/Compass Temperature Display will not function properly if the bus messages are not properly received. If no EVIC/Compass Temperature Display data is displayed, check the CAN Data Bus circuit communications, the RCM (if equipped), the Instrument Cluster functions and the Totally Integrated Power Module (TIPM). Any diagnosis of the RCM and EVIC/Compass Temperature Display system should begin with the use of a scan tool and the appropriate diagnostic service information.

For complete circuit diagrams, refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.

Scheme 53

A degaussing tool (Special Tool (special tool #6029, De Gauser)) is used to demagnetize, or degauss, the roof panel above the remote compass module. Equivalent units must be rated as continuous duty for 110/115 volts and 60 Hz. They must also have a field strength of over 350 gauss at 7 millimeters (0.25 inch) beyond the tip of the probe.

Scheme 54

Demagnetize the roof panel as follows

1. Be certain that the ignition switch is in the Off position, before you begin the demagnetizing procedure.
2. Place a piece of paper approximately 22 by 28 centimeters (8.5 by 11 inches), oriented on the vehicle lengthwise from front to rear, on the exterior surface of the roof panel at the left D-pillar in the area of the compass module. The purpose of the paper is to protect the roof panel from scratches, and to define the area to be demagnetized.
3. Connect the degaussing tool to an electrical outlet, while keeping the tool at least 61 centimeters (2 feet) away from the compass unit.
4. Slowly approach the center line of the roof panel at the windshield header, with the degaussing tool connected.
5. Contact the roof panel with the plastic coated tip of the degaussing tool. Be sure that the template is in place to avoid scratching the roof panel. Using a slow, back-and-forth sweeping motion, and allowing 13 millimeters (0.50 inch) between passes, move the tool at least 11 centimeters (4 inches) to each side of the roof center line, and 28 centimeters (11 inches) back from the windshield header.
6. With the degaussing tool still energized, slowly back it away from the roof panel. When the tip of the tool is at least 61 centimeters (2 feet) from the roof panel, disconnect the tool.
7. Calibrate the compass and adjust the compass variance. Refer to «MODULE, COMPASS , STANDARD PROCEDURE»(/jeep/grand-cherokee/wk2-2010-2013/remont/communication-devices/#message-center-service-information) .

Scheme 55

Compass variance, also known as magnetic declination, is the difference in angle between magnetic north and true geographic north. In some geographic locations, the difference between magnetic and geographic north is great enough to cause the compass to give false readings. If this problem occurs, the compass variance must be set.

Note. If the vehicle is taken on long trips into a new variance zone the compass function may be effected. Compass variance will need to be updated to the new zone number to function properly.

Note. The default for the compass variance from the factory is 8.

SET THE COMPASS VARIANCE MANUALLY AS FOLLOWS

1. Using the Variance Settings Map, find your geographic location and note the zone number.
2. Turn the ignition switch to the ON/RUN position. Press and release the SCROLL push buttons (5 or 6) until "System Set-up" is displayed and highlighted.
3. Press and release the STEP push button (3) to open the menu.
4. Using the scroll buttons, scroll through until " Compass Variance" is displayed and highlighted.
5. Momentarily depress and release the STEP push button to begin.
6. Using the same button toggle through the zone numbers (1-15), until the zone number for your geographic location appears in the display. The zone number will set automatically. NOTE: The default for the compass variance from the factory is 8. During programming, the Zone value will wrap around from Zone 15 to Zone 1.
7. Momentarily depress and release the BACK push button (4) return to the main menu.
8. Confirm that the correct direction is now indicated by the compass.
9. Using the scroll button (5 and 6), select " Turn Off Menu " to exit.

MANUAL COMPASS CALIBRATION

Note. Confirmation that the proper variance zone is programmed, is recommended whenever manual compass calibration is performed, for the appropriate procedure, refer to MODULE, COMPASS , STANDARD PROCEDURE .

The electronic compass unit features a self-calibrating design, which simplifies the calibration procedure. This feature automatically updates the compass calibration while the vehicle is being driven. This allows the compass unit to compensate for small changes in the residual magnetism that the vehicle may acquire during normal use. If the compass readings appear to be erratic or the Electronic Vehicle Information Center (EVIC) displays "CAL", perform the following manual calibration procedure. Also, any time EVIC service replacement components are installed, they must be calibrated using this procedure. Do not attempt to calibrate the compass near large metal objects such as other vehicles, large buildings, or bridges; or, near overhead or underground power lines.

Note. Do not attempt to calibrate the compass near large metal objects such as other vehicles, large buildings, or bridges; or, near overhead or underground power lines.

CALIBRATE THE COMPASS MANUALLY AS FOLLOWS

1. Start the engine but leave the vehicle in "PARK".
2. Press and release the SCROLL push buttons (5 or 6) until "System Set-up" is displayed and highlighted.
3. Press the STEP push button (3) to open the menu.
4. Using the scroll buttons, scroll through until " Calibrate Compass " is displayed and highlighted.
5. Momentarily depress and release the STEP push button to initiate the calibration procedure. The "CAL" symbol will come on solid in the EVIC display next to the compass direction that is displayed.
6. Slowly drive the vehicle on a level surface, away from large metal objects and power lines, through one or two complete circles not exceeding 8 km/h (5 mph). The "CAL" message will disappear from the display to indicate successful compass calibration.
7. Confirm that the correct direction is now indicated by the compass.
8. Using the scroll button, select " Turn Off Menu " to exit.

Note. If the compass display indicates an inaccurate compass heading or the display is locked up, the RCM (if equipped) may be inoperative and require replacement.

Note. If the "CAL" message remains in the display, either there is excessive magnetism near the compass, or the EVIC is inoperative. Attempt the calibration procedure at least one more time before performing EVIC diagnosis.

Note. If the wrong direction is still indicated in the compass display, the area selected for calibration may be too close to a strong magnetic field. Repeat the manual calibration procedure in another location.

Scheme 58

The ambient temperature sensor is a variable resistor type sensor that is mounted behind the radiator grille assembly on the left side of the vehicle.

The ambient temperature sensor cannot be adjusted or repaired, if inoperative or damaged, it must be replaced.

The ambient temperature sensor is a variable resistor that operates on a five-volt reference signal sent by the Totally Integrated Power Module (TIPM). The resistance in the sensor changes as temperature changes, changing the temperature sensor signal circuit voltage to the TIPM. Based upon the resistance in the sensor, the TIPM senses a specific voltage on the temperature sensor signal circuit. The TIPM then translates the voltage into a temperature reading that it sent over the Controller Area Network (CAN) data bus circuit to other modules utilizing temperature information.

AMBIENT TEMPERATURE SENSOR

The temperature function is supported by the ambient temperature sensor, a wiring circuit, and the Totally Integrated Power Module (TIPM). When the sensor is exposed to temperatures above 60° C (140° F), or if the sensor circuit is shorted, 60° C (130/140° F) will appear in the display in place of the temperature. When the sensor is exposed to temperatures below - 40° C (- 40° F) or if the sensor circuit is open, - - ° C (- - ° F) will be displayed on Electronic Vehicle Information Center (EVIC) equipped vehicles.

Note. The system displays the last known temperature when starting the vehicle and may take some time/mileage to update to an accurate current reading, up to 5 minutes at a maintained speed above 40 mph (64.3 kph). Customers with very short commutes may not get an updated reading before the vehicle is turned off, or if the ignition does not remain in the OFF position for more than 255 minutes (4hrs. 15min.). This strategy was intended to eliminate wildly fluctuating readings and may cause some customer confusion leading to unnecessary diagnostics/parts replacements.

SENSOR TEST

1. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable. Disconnect the ambient temperature sensor harness connector.
2. Measure the resistance of the ambient temperature sensor. At - 40° C (- 40° F), the sensor resistance is 336 kilohms. At 55° C (130° F), the sensor resistance is 2.488 kilohms. The sensor resistance should read between these two values. If OK, refer to appropriate Electrical Diagnostic article. If not OK, replace the inoperative ambient temperature sensor.

The ambient temperature sensor circuit can also be diagnosed using the following Sensor Test, and Sensor Circuit Test. If the temperature sensor and circuit are confirmed to be OK, but the temperature display is inoperative or incorrect, test the EVIC operation. Refer to CENTER, ELECTRONIC VEHICLE INFORMATION , DIAGNOSIS AND TESTING .

SENSOR CIRCUIT TEST

Refer to the appropriate wiring information for complete circuit schematic or connector pin-out information.

1. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable. Disconnect the wire harness connectors from the ambient temperature sensor and the TIPM.
2. Connect a jumper wire between the two terminals in the body half of the ambient temperature sensor harness connector.
3. Check for continuity between the sensor return circuit and the ambient temperature sensor signal circuit cavities of the TIPM harness connector. There should be continuity. If OK, refer to 4 . If not OK, repair the open sensor return circuit or ambient temperature sensor signal circuit to the ambient temperature sensor as required.
4. Check for continuity between the ambient temperature sensor signal circuit cavity of the TIPM harness connector and a good ground. There should be no continuity. If OK, test the EVIC operation. Refer to «CENTER, ELECTRONIC VEHICLE INFORMATION , DIAGNOSIS AND TESTING»(/jeep/grand-cherokee/wk2-2010-2013/remont/communication-devices/#message-center-service-information) . If not OK, repair the shorted ambient temperature sensor signal circuit as required.

The most reliable, efficient and accurate means to diagnose the ambient temperature circuit requires the use of a scan tool and the proper diagnostic procedure information. Refer to wiring for the appropriate information.
