tool screen to retrieve the DTC’s 3. Locate the Diagnostic Link Connector (DLC),
which is usually under the left-hand side of the in-
strument panel.
4. Start the engine and drive the vehicle until the
transaxle goes into the failsafe mode.
5. Park the vehicle, but do not turn the ignition
OFF. Allow it to idle.
6. Attach a voltmeter (analog or digital) to the test
terminals on the Diagnostic Link Connector (DLC).
The negative lead should be attached to terminal 4
and the positive lead to terminal 1.
7. Observe the voltmeter and count the flashes
(or arm sweeps if using an analog voltmeter); note
the applicable codes.
- 8. After all of the DTC(s) have been retrieved, fix
the applicable problems, clear the codes, drive the
vehicle, and perform the retrieval procedure again to
ensure that all of the codes are gone.

Control module reset procedures are a very im-
portant part of OBD II System diaqnostics.
This step should be done at the end of any fault
code repair and at the end of any driveability repair.

The Federal government decided that it was time
to create a standard for vehicle diagnostic systems
codes for ease of servicing and to insure that certain
of the vehicle’s systems were being monitored for
emissions purposes. Since OBD II codes are stan-
dardized (they all contain one letter and four num-
bers), they are easy to decipher.
The OBD II system in the Mitsubishi models is de-
signed so that it will flash the DTC’s out on a volt-
meter (even though a scan tool is better). However,
the first two characters of the code are not used. This
is because the transaxle is a part of the powertrain, so
all transaxle related codes will begin with a P. Also, *The MIL will may also be de-activated for
some codes if the vehicle completes three
consecutive trips without a fault detected
with vehicle conditions similar to those pre-
sent during the fault.
WITHOUTASCAN TOOL
If there are still codes p
resent, either the codes
were not properly cleared f
:Are the codes identical to
those flashed out previous

problem is still there (Are I
only some of the codes the
same as oreviouslv?).
since there are no overlapping numbers between SAE
and Mitsubishi codes, the second digit is also not
necessary.
The system flashes the codes o

Vehicle speed es446e35 Fig. 92 For OBO ii code retrieval without us-
ing a scan tool on Mitsubishi models, con-
nect the DVOM and jumper wire as shown
In 1996, all Mitsubishi switched from an arbitrary
code listing and format, to the federally regulated On
Board Diagnostics 2nd Generation (OBD II) code sys-
tern. Normally, OBD II equipped vehicles do not have
the option of allowing the person servicing the vehi-
cle to flash the codes out with a voltmeter; usually a
scan tool is necessary to retrieve OBD II codes. Mit-
subishi, however, does provide this option, earlier in this section. This is very important, since a
loose or disconnected wire, or corroded connector
terminals can cause a whole slew of unrelated DTC’s
to be stored by the computer; you will waste a lot of
time performing a diagnostic “goose chase.”
2. Grab some paper and a pencil or pen to write
down the DTC’s when they are flashed out. tent

Following are vacuum magrams for most of the
engine and emissions package combinations covered
by this manual Because vacuum circuits will vary
based on various engine and vehicle options, always
refer first to the vehicle emission control Information
label, if present. Should the label be missing, or
should vehicle be equipped with a different engine
from the vehicle’s original equipment, refer to the di-
agrams below for the same or similar configuration.
If you wish to obtain a replacement emissions la-
bel, most manufacturers make the labels available for
lurchase. The labels can usually be ordered from a
ocal dealer.
A vacuum diagram is typically affixed to a
label in the engine compartment
