Dodge Neon / Neon SRT-4. Manual - part 101
working, refer to the self-diagnostic test below. If the
mirror doesn’t light up or function, proceed with the
following preliminary tests:
(1) Disconnect
the
compass/temperature
mirror
electrical connector. Using a voltmeter, check for 12v
on the fused B+ circuit cavity. Voltage should be
present. If OK go to Step 2, If NOT OK, repair the
short or open circuit as required.
(2) Using a voltmeter, check for 12v on the fused
ignition run circuit cavity with the ignition switch in
the RUN position. Voltage should be present. If OK
go to Step 3, If NOT OK, repair the short or open cir-
cuit as required.
(3) Key Off. Using a ohmmeter, check for continu-
ity to a good ground on the ground circuit cavities of
the compass/temperature mirror electrical connector.
Continuity should be present. If OK, replace the mir-
ror assembly, If NOT OK, repair the short or open
circuits as required.
COMPASS/TEMPERATURE MIRROR SELF-
DIAGNOSTIC TEST
NOTE: If the ignition switch is turned off during any
period of the self diagnostic procedure, the mirror
will exit the self diagnostic mode.
NOTE: Pressing and releasing the zone/calibration
button will exit the self diagnostic mode and return
to the standard compass/temperature mode
To perform the compass/temperature mirror self
diagnostic routine:
(4) Turn the ignition to the ON position.
(5) Press and hold the zone/calibration (left read-
ing lamp button) button for 20 to 25 seconds.
(6) During testing, if any of the test fail, a “F” will
appear. If more than one test fail, “F0” will appear. If
“F” or F0” appear, replace the compass/temperature
mirror. (Refer to 23 - BODY/INTERIOR/REAR VIEW
MIRROR - REMOVAL).
(7) If a “P” is displayed, that indicates that the
compass/temperature mirror has passed the self diag-
nostic procedure.
NOTE: If, after performing the self diagnostic proce-
dure the compass still has an incorrect reading,
perform the compass calibration or compass varia-
tion adjustment. (Refer to 8 - ELECTRICAL/POWER
MIRRORS/POWER MIRROR - STANDARD PROCE-
DURE - COMPASS CALIBRATION) or (Refer to 8 -
ELECTRICAL/POWER MIRRORS/POWER MIRROR -
STANDARD PROCEDURE - COMPASS VARIATION
ADJUSTMENT).
STANDARD PROCEDURE
STANDARD PROCEDURE - COMPASS
CALIBRATION
The electronic compass unit features a self-cali-
brating design, which simplifies the calibration pro-
cedure.
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 read-
ings appear to be erratic or out of calibration, per-
form the following calibration procedure. Also, new
service replacement compass/temperature mirrors
must have their compass calibrated using this proce-
dure. Do not attempt to calibrate the compass near
large metal objects such as other vehicles, large
buildings, or bridges; or, near overhead or under-
ground power lines.
FIRST TIME COMPASS CALIBRATION
The mirror is shipped in the first time calibration
mode with the CAL symbol illuminated. After com-
pleting three 360° turns in an area free from large
metal objects, the CAL symbol should turn off and
the compass will function normally.
MANUAL COMPASS CALIBRATION
(1) Press and hold the Zone/Calibration (left read-
ing lamp button) button for 10 to 15 seconds. This
will toggle the CAL mode on/off, causing the CAL
symbol to illuminate/darken respectively.
(2) Release the button once the CAL symbol illu-
minates/darkens. Manual compass calibration has
been initiated at this point.
(3) Drive the vehicle in circles in an area free from
large metal objects until the CAL symbol is no longer
displayed.
When the CAL symbol is no longer displayed, the
compass is calibrated and should display correct
headings. Verify proper calibration by checking North
(N), South (S), East (E), and West (W). If the com-
pass does not appear accurate, repeat the calibration
procedure in another area.
NOTE: If the “CAL” message remains in the display,
either there is excessive magnetism near the com-
pass, or the unit is faulty. Repeat the calibration
procedure at least one more time.
NOTE: If the wrong direction is still indicated in the
compass display, the area selected for calibration
may be too close to a strong magnetic field. Repeat
the calibration procedure in another location.
