COMPASS/MINI-TRIP COMPUTER (Continued)
TRIP ODOMETER
Compass Mini-Trip Computer receives trip odome-
ter information from the Cluster over the PCI bus
line. If Compass Mini-Trip Computer displays dashes
-.- instead of the trip odometer value, it is not receiv-
ing a PCI bus message for the trip odometer from the
Cluster. To check out the PCI bus line and the BCM,
use the DRB lll scan tool.
ELAPSED TIME
Compass Mini-Trip Computer receives a PCI bus
message containing elapsed time information. If
Compass Mini-Trip Computer displays dashes -:--
instead of the elapsed time, it is not receiving a PCI
bus message for the elapsed time from the BCM. To
check out the PCI bus line and the BCM, use the
DRB lll scan tool.
COMPASS DISPLAY
To display the vehicle direction, the Compass Mini-
Trip Computer processes information from a sensor
internal to the module. The Compass Mini-Trip Com-
puter is self- calibrating and requires only variance
adjustments dependent upon location. The Compass
Mini-Trip Computer displays the label CAL whenever
the compass is in the fast calibration mode.
If all three of the following conditions listed below
occur, the vehicle must be demagnetized.
• Compass portion of the display is blank
• Temperature portion of the display is OK
• The label CAL is illuminated
If demagnetizing the vehicle is needed, refer to the
demagnetizing procedure
demagnetizing, to calibrate the compass refer to Cal-
ibration Procedure and to set the variance refer to
Variance Procedure, both within this section. If the
compass portion of the display is still blank, replace
the Compass Mini-Trip Computer.
