GENERAL INFORMATION 1
G E N E R A L I N F O R M A T I O N
An overhead console featuring an electronic com­
pass and thermometer is an available option for Ram
truck models. Following are general descriptions of
major components used in the overhead console. Re­
fer to Group 8W - Wiring Diagrams for complete cir­
cuit descriptions and diagrams.
J948C-2
COMPASS
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
display is turned on or off using the COMP/TEMP
button to the left of the display.
The self-calibrating compass unit requires no ad­
justing in normal use. The only calibration that may
prove necessary is to drive the vehicle in 3 complete
circles, on level ground, in not less than 48 seconds.
This will reorient the unit to its vehicle.
The 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 fasten­
ers that hold the assembly to the roof header can also
affect compass operation.
If the vehicle roof should become magnetized, the
demagnetizing and calibration procedures may be re­
quired to restore proper operation.
THEilOiETER
The thermometer displays the outside ambient
temperature. The temperature displayed can be
changed from Fahrenheit to Celsius using the US/
METRIC button. The displayed temperature is not
an instant reading of conditions, but an average tem­
perature. It may take the unit several minutes to re­
act to a major temperature change such as driving
out of a heated garage into winter temperatures.
When the ignition switch is turned OFF, the last dis­
played temperature reading stays in memory. When the
ignition switch is turned ON again, the thermometer
will display the memory temperature for one minute;
then update the display to the current average temper­
ature reading within five minutes.
READING AND COURTESY LAMPS
All reading and courtesy lamps in the overhead
console are activated by the door jamb switches.
When both doors are closed, the lamps can be indi­
vidually activated by depressing the corresponding
lens. When a door is open, depressing the lamp lens
switches will not turn the lamps off. Refer to Group
8L - Lamps, for diagnosis and service of these lamps.
