IGNITION OFF DRAW (IOD)
GENERAL INFORMATION
A normal electrical system will draw from 5 to 30
milliamperes from the battery. This is with the ignition
in the OFF position, and all non-ignition controlled cir-
cuits in proper working order. The amount of IOD will
depend on body model and electrical components. A ve-
hicle that has not been operated for an extended period
of approximately 20 days may discharge the battery to
an inadequate level. In this case, the Main Fusible Link
Connector should be disconnected. The Main Fusible
Link connector is located rearward of the battery on the
engine wiring harness (Fig. 19).
If the IOD is over 30 milliamperes, the defect must
be found and corrected before condemning the bat-
tery. Usually, the battery can be charged and re-
turned to service (Fig. 16).
IGNITION OFF DRAW (IOD) TESTS
VEHICLES WITHOUT ELECTRONIC AUTOMATIC TRANSMISSION/LOAD LEVELINGSUSPENSION OR ALARM SYSTEMS
Testing for HIGHER AMPERAGE IOD must be
performed first to prevent damage to most milliamp
meters. A standard 12 volt test light and a milliamp meter
that is equipped with two leads will be used for the
following tests. The milliamp meter should be able to
handle up to two amps.
(1) Verify that all electrical accessories are OFF.
Turn off all lights, close trunk lid, close glove box door,
turn off sun visor vanity lights, close all doors and re- move ignition key. Allow the Illuminated Entry System
if equipped to time out in approximately 30 seconds.
(2) Verify the engine compartment lamp bulb is
working by opening/closing hood. Remove the lamp. (3) Disconnect negative battery cable (Fig. 15).
(4) Connect a typical 12 volt test light between the
negative cable clamp and the negative battery post (Fig.
19). The test light may be brightly lit for up to three
minutes or may not be lit at all. This depending on the
body model or electronic components on the vehicle. (a) The term brightly used throughout the follow-
ing tests. This implies the brightness of the test light
will be the same as if it were connected across the
battery posts. This would be with a fully charged bat-
tery.
(b) The test light or the milliamp meter MUST
be positively connected to the battery post and the
battery cable during all IOD testing. (c) Do not allow the test light or the milliamp
meter to become disconnected during any of the
IOD tests. If this happens, the electronic timer
functions will be started and all IOD tests must be
repeated from the beginning. Clamp the test light
at both ends to prevent accidental disconnection.
(d) After three minutes time has elapsed, the test
light should turn OFF or be dimly lit depending on
the electronic components on the vehicle. If the test
light remains BRIGHTLY lit, do not disconnect test
light. Disconnect each fuse or circuit breaker until
test light is either OFF or DIMLY lit. Refer to the
Front Wheel Drive Car Wiring Diagrams Service
Manual. This will eliminate higher amperage IOD. It
is now safe to install the milliamp meter without
damage to the meter to check for low amperage IOD.
(e) Possible sources of high IOD are usually ve-
hicle lamps trunk lamp, glove compartment, lug-
gage compartment, etc.. (f) If test light is still brightly lit after discon-
necting each fuse and circuit breaker, disconnect
the wiring harness from the generator. Refer to
Generator Testing. Do not disconnect test light.
CAUTION: This last test has higher amperage IOD and
must be performed before going on with low amper-
age IOD tests. The higher amperage IOD must be elim-
inated before hooking up milliamp meter to check for
low amperage IOD. If higher amperage IOD has not
been eliminated, milliamp meter may be damaged.
Most milliamp meters will not handle over one or two
amps. Do not hook up meter if test light is glowing
brightly. Refer to maximum amperage specifications
and instructions supplied with milliamp meter.
After higher amperage IOD has been corrected, low
amperage IOD may be checked. The MAXIMUM IOD=
30 MILLIAMPERES.

VARIANCE SETTING PROCEDURE
There are two methods for setting variance while
in variance set mode. If the CAL symbol is on proce-
dure 2 must be used.
PROCEDURE 1
(1) Turn ignition switch to the on position.
(2) Press and hold the Comp/Temp button till the
display is turned OFF. (3) While continuing to hold Comp/Temp button
depress and hold US/Metric button until the VAR
symbol lights in approximately 5 seconds. (4) Release buttons.
(5) To determine the zone number which, corre-
sponds with your geographic area refer to Fig. 4.
(6) Press the US/Metric button until the zone num-
ber matches the display. (7) Press the Comp/Temp button to finish setting
of variation. (8) Variation is complete.
PROCEDURE 2 (1) Move away from any large metal objects like
buildings, or bridges. With the engine running and
the doors closed point vehicle true north. (2) Press and hold Comp/Temp button. The display
will go blank. (3) While continuing to hold Comp/Temp button
depress and hold the US/Metric button until the
VAR symbol lights in approximately 5 seconds. (4) Release buttons.
(5) Press the Comp/Temp button to finish setting
of variation. (6) Variation is complete.
DEMAGNETIZING PROCEDURE
Do not attach magnetic devices, such as magnetic
CB antennas to the vehicle roof, as they can cause
the compass to give false readings. Every vehicle has its own magnetic field. This
magnetic field is created by the various processes a
steel roof goes through when the vehicle is built. A
magnetic field also can be created if the roof is sub-
jected to A magnet, example:
² Magnetic c.b. antenna
² Magnetic tipped screwdriver and etc.
If the roof becomes magnetized use a demagnetiz-
ing Tool 6029 to demagnetize the roof. In this demagnetizing procedure you will use the
demagnetizing tool to demagnetize the roof and
mounting screws in the overhead console. It is impor-
tant that you follow the instructions below exactly.
The mounting screws and the mounting brackets
around the compass area are steel, and therefore aid
in the degaussing of the roof panel. (1) Be sure the ignition switch is in the OFF posi-
tion before you begin the demagnetizing procedure. (2) Open the sun glass compartment to gain access
to the overhead console mounting screws. (3) Plug the demagnetizing tool into a standard
110/115 volt AC outlet, keeping the demagnetizing
tool at least 12 inches away from the compass area
when plugging it in. (4) Slowly approach the console mounting screw
with the plastic coated tip of the tool for at least 2
seconds. (5) With the demagnetizing tool still energized,
slowly back it away from the screw until the tip is at
least 12 inches from the screw head. (6) After you have pulled at least 12 inches from
the last screw, remove the demagnetizing tool from
inside of the vehicle and disconnect it from the elec-
trical outlet. (7) Place an 8 1/2 in. X 11 in. piece of paper
lengthwise on the roof of vehicle directly above com-
pass. The purpose of the paper is to protect the roof
panel from scratches and define the area to be de-
magnetized.

8C - 4 OVERHEAD CONSOLE Ä

(8) Plug in the demagnetizing tool, keeping it at
least 2 feet away from the compass unit. (9) Slowly approach the center of the roof panel at
the windshield with the demagnetizing tool plugged
in.
² Contact the roof panel with the tip of the tool.
² Using slow sweeping motions of 1/2 inch between
sweeps
² Move the tool approximately 4 inches either side of
the centerline, and at least 11 inches back from the
windshield. (10) With the demagnetizing tool still energized,
slowly back away from the roof panel until the tip is
at least two feet from the roof before unplugging the
tool. (11) Recalibrate compass.
COMPASS DIAGNOSTICS
To place the unit into the diagnostics mode, turn
the vehicle ignition off. Depress the Comp/Temp but-
ton while turning on the ignition/run switch. The
display will then show DO. There are three tests that
can be performed when in the diagnostics mode.
Press the U.S./Metric button to choose test desired
(Fig. 5).
Test 1 (d1) determines the magnetic field strength
at the compass. The compass displays compensation
numbers which, correspond to the current magnetic
field strength at the compass. The letter N is dis-
played in the compass portion of the display. While a
number which, corresponds to the magnetic field
strength in the North/South direction is displayed.
The temperature portion of the display or the letter
W is displayed in the compass portion of the display. A number which, corresponds to the magnetic field
strength in the East/West direction is displayed in
the temperature portion of the display. For proper
compass operation the numbers should be between 1
and 14. A number of 7 or 8 is ideal (no vehicle mag-
netism) while numbers approaching 1 or 14 show
that the vehicle is highly magnetic. If the numbers
show that the vehicle is highly magnetic, perform
the demagnetized procedure in this Group and retest
for magnetism at compass. Test 2 (d2) checks the electronic circuits of the
compass, temperature. If the test passes d2 will be
displayed, and if the test fails F2 will be displayed.
Refer to Body Diagnostic Procedure Manual for fur-
ther testing procedures. Test 3 (d3) performs a walking segment test which,
sequentially puts different directions and numbers on
the display. If any segment fails, replace the compass
module.
SELF-DIAGNOSTIC TEST
(1) With the ignition switch in the OFF position si-
multaneously press the Comp/Temp button and the
US/Metric button. (2) Turn ignition switch ON.
(3) Continue to hold both buttons until the display
performs a walking segment test. This checks for
open or shorted segments. To repeat the test press
the Comp/Temp button. (4) Press the US/Metric button, all segments will
light for about 2 seconds. To repeat the test press the
Comp/Temp button. (5) Press the US/Metric button to return to normal
operation.
