Compass: Description and Operation
SYSTEM OPERATION
The compass will display the direction in which the vehicle is pointed using the eight major compass headings (Examples: north is N, northeast is
NE). It does not display the headings in actual degrees.
The self-calibrating compass unit requires no adjusting in normal use. The only calibration that may prove necessary is to drive the vehicle in three
complete circles, on level ground, in not less than 48 seconds. This will reorient the compass unit to its vehicle.
The compass unit also will compensate for magnetism the body of the vehicle may acquire during normal use. However, avoid placing anything
magnetic directly on the roof of the vehicle. Magnetic mounts for an antenna, a repair order hat, or a funeral procession flag can exceed the
compensating ability of the compass unit if placed on the roof panel.
Magnetic bit drivers used on the fasteners that hold the overhead console assembly to the roof header can also affect compass operation. If the
vehicle roof should become magnetized, the demagnetizing and calibration procedures found may be required to restore proper compass operation.
The compass, trip computer, and thermometer display module cannot be repaired, and are only available for service as a unit. If faulty or damaged,
the complete module must be replaced.
