Electronic Vehicle Information Center (EVIC)
A new overhead console (EVIC), on models equipped with this option, combines features of the Overhead Travel Information System (OTIS) into an Electronic Vehicle Information Center (EVIC). The Electronic Vehicle Information Center includes a unique interface that allows customers to program operation of several electronic features to suit their individual preferences. The EVIC may also include the HomeLink(R) universal remote transceiver.

A blue-green vacuum-fluorescent 80 x 16 dot matrix screen displays the information. The screen also displays a vehicle icon that is used for door ajar indications and to show if a turn signal has been left ON. The console also houses courtesy/reading lamps.

Vehicle Information Display
The Vehicle Information Center provides the following functions:
- Compass direction
- Current outside temperature
- Elapsed time
- Miles/kilometers to empty
- Average fuel economy
- Instantaneous fuel economy
- Trip odometer (ODO)
- Miles/kilometers to service
- Blank screen
- Warning messages:
- TURN SIGNALS ON (with vehicle icon)
- PERFORMANCE SERVICE
- DOOR AJAR (one or more, with vehicle icon)
- WASHER FLUID LOW (with graphic)

The appearance of warning messages is accompanied by a beep.

All of the information required by the EVIC is transmitted over the PCI bus from the BCM or PCM.

Vehicle Icon Displayed Ajar Messages
The BCM and the door modules monitor all door switches and broadcasts a PCI bus status message to the EVIC. If a door is opened or closed the EVIC responds by changing the appropriate icon and message. The door icons and messages will not update if the EVIC cannot detect the bus message. If the car is moving at critical speed and any door is open, the appropriate message and icon will be displayed. A beep request will be generated when critical speed is reached for the first time.

Programmable Features
For each programmable feature, pressing the MENU button selects the menu of programmable features, which always begins with Language. Pressing the STEP button cycles the available choices. Continued pressing of the MENU button accepts the new choice and selects successive features for possible programming/reprogramming. Pressing the C/T (compass-temperature display selector) button returns the display to the normal (compass temperature display) mode. When the sequence is complete, the display also returns to the normal mode. Features that are dependent on vehicle equipment; such as REMOTE LINKED TO MEMORY, EASY EXIT, only appear if applicable.

- Customer Programmable Features:

- LANGUAGE?
The Driver may select English, Francaise, Deutsch, Italiana, Espanol. The word Language is always in English regardless of which language is selected. All other display nomenclature, including the trip computer functions, appears in the selected language.

- DISPLAY US OR METRIC?
Toggles the trip computer temperature, fuel economy, and odometer display readings between the two sets of units. It also changes the odometer display in the instrument cluster.

- AUTO DOOR LOCKS?
When this feature is selected, all doors lock automatically when vehicle speed reaches 15 mph (25 km/h). Previously this feature could be programmed only by a dealer.

- AUTO UNLOCK ON EXIT?
When automatic locking is chosen, automatic unlocking may also be selected. When selected, all doors will unlock when the driver's door is open if the vehicle is stopped and the transmission is in Park or Neutral.

- REMOTE UNLOCK?
The driver may choose to have all the doors unlock at the first press of the unlock button, or unlock only the driver's door on the first press and require a second press to unlock all doors.

- REMOTE LINKED TO MEMORY?
When chosen, the Memory System will select memorized seat, mirror and radio settings when an RKE (remote keyless entry) transmitter unlock button is pressed. If not chosen, selection of memorized settings may still be done using the memory buttons.

- FLASH LAMP ON LOCK/UNLOCK?
If enabled, front and rear turn signal lamps will flash once when the doors are locked, and twice when the doors are unlocked using the RKE transmitter. This feature may be selected with or without SOUND HORN ON LOCK?

- HEAD LAMP DELAY
The driver may choose to have the head lamps remain ON, when leaving the vehicle, for 30 seconds, 60 seconds, 90 seconds or not at all.

- HEAD LAMPS ON WITH WIPERS?
On vehicles with the automatic head lamps, the driver may choose to have the head lamps turn ON simultaneously with the windshield wipers. If the head lamps were turned ON in this way, they will also turn OFF the wipers.

- SERVICE INTERVAL
This feature selects an interval from 2000 to 7500 miles (3200 to 12,000 kilometers) in 500 mile (800 kilometer) increments between PERFORM SERVICE alert messages. When service has been performed, the counter is reset by pressing and holding the RESET button for 3 seconds as before.

- RESET SERVICE DISTANCE?
IF SERVICE INTERVAL is changed, this message asks if the accumulated service distance should be reset to 0 because the service was performed.

- EASY EXIT SEAT?
If enabled, the driver's seat moves rearward two inches (55 mm) (or to the farthest rearward position, if this is less) when the key is removed from the ignition switch to facilitate driver exit from the vehicle. If the REMOTE LINKED TO MEMORY feature is enabled, the seat will return to the memorized position when the RKE unlock button is pressed.

- TILT MIRRORS DOWN?
This programmable feature only applies to vehicles equipped with the optional memory system. The options include Yes and No. The default is No. When Yes is selected, and the vehicle is placed in reverse, the exterior mirrors tilt down towards the ground. Once reverse is disengaged, the exterior mirrors will return to their original position.

- TRAIN REMOTE?
The options include Yes and No. The default is No. When Yes is selected and the MENU button is pressed: a chime will sound and the EVIC will display "PRESS REMOTE LOCK & UNLOCK THEN PRESS UNLOCK". You have approximately 30 seconds to train up to 4 remote key fobs: after each remote key fob is trained a chime will sound indicating that the EVIC has received the training sequence. When you have finished training the remote key fobs, press the Menu button again and the EVIC will display "TRAIN DONE, x TRAINED". If no remote key fobs are pressed within approximately 30 seconds the EVIC will display "TRAIN TIMEOUT".

Memory Messages
- MEMORY #X POSITION SET (X -1 OR 2)
This message appears when the Memory System is programmed. It is accompanied by a chime tone.

- MEMORY SYSTEM DISABLED
This message appears when the driver presses a memory button or the RKE unlock button with the seat belt fastened, and/or the vehicle moving to notify the driver why memory action did not occur.

SETTING THE COMPASS
Compass Calibration

CAUTION: DO NOT PLACE ANY EXTERNAL MAGNETS, SUCH AS MAGNETIC ROOF MOUNT ANTENNAS, IN THE VICINITY OF THE COMPASS. DO NOT USE MAGNETIC TOOLS WHEN SERVICING THE OVERHEAD CONSOLE.

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 out of calibration, perform the following calibration procedure. Also, new service replacement Electronic Vehicle Information Center (EVIC) modules must have their compass calibrated using this procedure. Do not attempt to calibrate the compass near large metal objects such as other vehicles, large buildings, bridges, or near overhead or underground power lines.

NOTE: WHENEVER THE COMPASS IS CALIBRATED MANUALLY, THE VARIANCE NUMBER MUST ALSO BE RESET. FOR COMPASS CALIBRATION SEE THE APPROPRIATE SECTION OF THE SERVICE INFORMATION.

If the module displays the temperature while the compass is blank, or displays a false reading, the vehicle must be demagnetized. See the service information for the proper procedure.

If the compass still goes blank after the vehicle is demagnetized, the EVIC must be replaced.

Compass Variation Adjustment - 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 setting may need to be changed.

To set the compass variance:
1. Using the Variance Settings map, find your geographic location and note the zone number.
2. Turn the ignition switch to the ON position. If the compass/thermometer data is not currently being displayed, momentarily depress and release the C/T push button to reach the compass/thermometer display.
3. Depress the Reset push button and hold the button down until "VARIANCE = XX" appears in the display. This takes about five seconds.
4. Release the Reset push button. "VARIANCE= XX" will remain in the display. "XX" equals the current variance code setting.
5. Momentarily depress and release the Step push button to step through the zone numbers, until the zone number for your geographic location appears in the display.
6. Momentarily depress and release the Reset push button to enter the displayed zone number into the EVIC module memory.
7. Confirm that the correct directions are now indicated by the compass.





Homelink(r) Universal Transmitter
The HomeLink Universal Transmitter is optional with the standard overhead console. For added security it will operate home security systems that use coded signals known generically as rolling codes to increase security. The overhead console display provides visual feedback to the driver, showing which HomeLink transmitter button is pressed. As on prior models, HomeLink can learn and store three separate transmitter radio frequency codes to operate garage door openers, security gates, and security lighting. Buttons are marked with one, two or three raised dots for identification by touch.

Self-Diagnostic Test
The self-diagnostic test is used to determine that the internal circuitry and compass are operating properly, and all PCI bus messages are being received for initial operation. The button backlighting is also verified by flashing the bulbs for proper operation.

Initiate the self-diagnostic test as follows:
1. With the ignition switch in the OFF position, simultaneously press and hold the C/T button and the RESET button.
2. Turn the ignition switch to the ON position.
3. Continue to hold both buttons until the software versions are displayed.
4. The display will show the result of the self-diagnostic test. If the display reads:
a. PASS SELF TEST - press the RESET button to return to the compass/temperature display. The EVIC is working properly.
b. FAILED SELF TEST - an internal failure has occurred. Replace EVIC.
c. FAILED J1850 COMMUNICATION - see diagnostics for further information,

Ambient Temperature Sensor
The thermometer function is supported by the ambient temperature sensor, a wiring circuit, the Powertrain Control Module (PCM), the Programmable Communications Interface (PCI) data bus, and portion of the Electronic Vehicle Information Center (EVIC) module. If any portion of the ambient temperature sensor circuit fails, the PCM will self-diagnose the circuit and set a DTC.

The EVIC will lock the display at 54 °C (130 °F) if the sensor is exposed to temperatures above 54 °C (130 °F), or if the sensor is shorted. The EVIC will lock the display at -40 °C (-40 °F) if the sensor is exposed to temperatures below -40 °C (-40 °F), or if the sensor circuit is open.

POWER DOOR LOCK SYSTEM
The door lock switches provide a variable amount of voltage through the multiplexed (MUX) circuit to the BCM. Depending upon that input and various conditions that must be met (i.e. door lock inhibit, etc.), the BCM will determine the action to be taken and activate the proper relay for approximately 250 to 350 msec. If the vehicle is equipped with the vehicle theft security system it will have the central locking feature which locks and unlocks all doors from the cylinder lock switches. These switches are on separate multiplexed circuits to the BCM and have trouble codes relating to each of them.

RKE Remote Keyless Entry - This feature allows locking and unlocking of the vehicle door(s) by remote control using a hand-held transmitter (sometimes referred to as a fob) to activate a radio receiver (RKE module). This module now plugs into the body control module which is directly connected to the junction block. With this feature RKE can now be added to a non-equipped vehicle by installing a module. If the vehicle is equipped with the vehicle theft security system, RKE will also arm and disarm that system. A 4-button transmitter is used which provides lock, unlock, decklid release and panic features. Decklid release is only operable while the vehicle is in the park position. The module is capable of retaining up to 4 transmitter codes. Rolling code, which increases security, is also included in this system. If the transmitter goes out of synchronization it is easily put back in by pressing the lock button when the transmitter is within range. An external antenna has been added which plugs into the module to provide greater range. RKE will also turn ON the interior lamps when a valid unlock command is received and will extinguish the interior lamps when a lock command is received and all doors are closed.

On a vehicle equipped with the memory system, when the unlock button on a specified transmitter (either #1 or #2) is pressed the BCM will send a recall message to both the MHSMM and the PCI radio. They will in turn position the driver seat and both mirrors along with setting the radio presets.

Door Lock Inhibit - When the key is in the ignition and the driver front door is open, all door lock switches are disabled. The unlock switches are still functional. This protects against locking the vehicle with the keys still in the ignition.

Automatic (rolling) Door Locks - This feature can be enabled or disabled by using either the DRBIII(R) or the customer programmable method. When enabled, all doors will lock when the vehicle reaches a speed of 15 mph (24 kmh) and all doors are closed. If a door is opened and the vehicle slows to below 15 mph (24 kmh), the locks will operate again once all doors are closed and the speed is above 15 mph (24 kmh).

Decklid Release - Decklid release is now a function of the body control module. Trouble codes are provided to assist in the diagnosis of this system.

Customer programmable features are: Horn chirp, one or two press decklid release, programming a new transmitter (using a previously programmed transmitter) and rolling door locks.
