Console: Description and Operation
OVERHEAD CONSOLECompass/Mini-trip Computer (CMTC)
The compass/mini-trip computer is located in the overhead console. It displays to the driver the direction the vehicle is traveling and the current outside temperature, as well as the following traveler navigational information: average fuel economy (AVG ECO), distance to empty (DTE), instantaneous fuel economy (ECO), elapsed time (ET), and trip odometer (ODO). The information needed for the CMTC functions is received over the PCI bus from other modules.
Electronic Vehicle Information Center (EVIC)
The Electronic Vehicle Information Center (EVIC) includes all the same function and is located in the same area as the Compass/Mini-Trip Computer, but it adds a number of warning messages. Also, the trip computer messages are spelled out on the screen, for example, DISTANCE TO EMPTY where the Mini-Trip Computer displays only shows DTE.
If the compass/mini-trip computer or EVIC has been replaced, it may be necessary to reset the calibration.
Setting The Compass
The compass/mini-trip module and EVIC are self-calibrated and requires no adjustment. The word CAL will be displayed to indicate that the compass is in the fast calibrating mode. CAL will turn off after the vehicle has gone in three complete circles without stopping, in an area free of magnetic disturbance.
If the module displays the temperature while the compass is blank or shows a false reading, the vehicle must be demagnetized.
If the compass still goes blank after the vehicle is demagnetized, the compass/mini-trip/EVIC module must be replaced.
Setting The Variance
Variance is the difference between magnetic north and geographic north. To determine the variance for the area you are in, refer to the following zone map provided. The number shown for your area is the variance number for your area.
1. Set the compass/mini-trip console (CMTC) to compass/temperature mode.
2. Press and hold down the RESET button for 5 seconds. NOTE: If the button is held for 10 seconds instead of 5, the CMTC will set the variance to 8 and enter the fast calibration mode.
3. The VAR light will come ON and the last variance setting will be displayed.
4. Press the STEP button to set the zone number.
5. Press the US/M button and resume normal operation.
NOTE: DO NOT ATTACH ANY MAGNETIC DEVICE SUCH AS A MAGNETIC CB ANTENNA TO THE VEHICLE. THIS CAN CAUSE THE COMPASS TO GIVE FALSE READINGS.
