CHECK MODE PROCEDURE
HINT:
Hand−held tester only:
Check mode has a higher sensitivity to detect malfunctions and
can detect malfunctions that normal mode cannot detect.
Check mode can also detect all the malfunctions that normal
mode can detect.
1. CHECK MODE PROCEDURE(Using the hand−held
tester)
(a) Turn the ignition switch to OFF.
(b) Connect the hand−held tester to the DLC3.
(c) Turn the ignition switch to ON and turn the hand−held tes-
ter ON.
(d) Select the item: DIAGNOSIS / OBD/MOBD / CHECK
MODE.
NOTICE:
All DTCs and freeze frame data recorded will be erased if:
1) the hand−held tester is used to change the ECM from
normal mode to check mode or vice versa; or 2) during
check mode, the ignition switch is turned from ON to ACC
or OFF.
(e) Start the engine. The CHK ENG should turn off after the
engine starts.
(f) Simulate condition of the malfunction described by the
customer or freeze frame data.
(g) After simulating the malfunction condition, use the hand−
held tester diagnosis selector to check the DTCs, freeze
frame data and other data.
(h) After checking the DTCs, inspect the applicable parts.
2. CLEAR DTCs (Using the hand−held tester)
(a) Connect the hand−held tester to the DLC3.
(b) Turn the ignition switch to ON and turn the hand−held tes-
ter ON. (Do not start the engine)
(c) Select the item: DIAGNOSIS / OBD/MOBD / DTC INFO
/ CLEAR CODES.
(d) Clear DTCs and freeze frame data.
HINT:
If you need help with the hand−held tester, refer to its instruction
book.
(e) Disconnect the battery terminal or remove the ECD fuse
from the engine room R/B for more than 60 seconds.

DIAGNOSIS SYSTEM
1. DESCRIPTION
S When troubleshooting Euro −OBD vehicles, the only dif-
ference from the usual troubleshooting procedure is that
you c onnect an O BD scan t ool com plying wit h I SO
1 503 1− 4 or a hand −held tester to the vehicle, and read
the various data output from the vehicle’s ECM.
S Eur o −O BD r egulat ions r equir e t hat t he v ehicle’s on −
board computer illuminates the check engine warning
light (CHK ENG) on the instrument panel when the com-
puter detects a malfunction in the emission control sys-
tem / components or in the power train control compo-
nents which affect vehicle emissions, or a malfunction in
t he c om put er. I n addit ion, t he applicable Diagnost ic
Trouble Codes (DTCs) prescribed by ISO 1503 1− 4 are
recorded in the ECM memory (see page 05 −299). If the
malfunction does not reoccur in 3 consecutive trips, the
CHK ENG goes off automatically but the DTCs remain re-
corded in the ECM memory.
S To check the DTCs, connect the OBD scan tool or hand −
held tester to Data Link Connector 3 (DLC3) on the ve-
hicle. The OBD scan tool or hand −held tester also en-
ables you to erase the DTCs and check the freeze frame
data and various forms of engine data. (For operating
instructions, see the OBD scan tool’s instruction book.)
S DTCs include ISO controlled codes and manufacturer
controlled codes. ISO controlled codes must be set as
pr escr ibed by t he I SO , while m anuf act ur er c ont r olled
codes can be set by the manufacturer within the pre-
scribed limits (see DTC chart on page 05 −299).
S The diagnosis system operates in normal mode during
normal vehicle use. It also has check (test) mode for tech-
nicians to simulate malfunction symptoms and trouble-
shoot. Most DTCs use 2 trip detection logic* to prevent er-
roneous detection, and to ensure a thorough malfunction
detection. By switching the ECM to check mode using
hand −held tester when troubleshooting, a technician can
cause the CHK ENG to illuminate for a malfunction that
is only detected once or momentarily. (Hand −held tester
only) (see page 05 −29 1)
S* 2 trip detection logic
When a malfunction is first detected, the pending fault
code is stored in the ECM memory ( 1st trip). If the same
malfunction is detected again during the second drive
test, this second detection causes the CHK ENG to illumi-
nate (2nd trip). (However, the ignition switch must be
turned OFF between the 1st trip and 2nd trip.)

REGISTRATION
NOTICE:
S The injector compensation code will be required to register with the ECM when replacing injec-
tors or the ECM.
S If an incorrect injector compensation code was registered with the ECM, it may rattle the engine
assembly or the engine idling may become rough. In addition, it may become a cause of engine
failure or shorten the life of the engine.
1 . If you replace the ECM with a new one, register all the injector compensation codes with the
new ECM as follows:
(a) Prior to replacing the ECM, read all the compensation codes stored in the existing ECM using the hand−held tester, and then write them down (see page 05 −273).
(b) After replacing the ECM, enter the written compensation codes into the ECM using the hand −held tes-
ter (see page 05 −277).
(c) Turn the ignition switch to OFF and turn the hand −held tester OFF, then wait for 30 seconds or more.
(d) Turn the ignition switch to ON and turn the hand −held tester ON, then clear DTC P 160 1using the
hand −held tester (see page 05 −290).
HINT:
SIn order to optimize the injector’s fuel injection characteristic, the ECM compensates the injection dura-
tion by each cylinder. The ECM stores and uses compensating data in the form of a 30 −digit −alphanu-
meric value that is imprinted on the head portion of each injector as the injector compensation code.
SIf you installed a new injector, its own injector compensation code is needed to register with the ECM.
Also, if you replaced the ECM, the compensation codes of all the injectors are needed to register be-
cause the new ECM dose not have the codes until they are registered.
SOnce the ECM is replaced, DTC P 160 1will be present when turning the ignition switch to ON. This
is to inform you that the injector compensation codes are required to register with the ECM. In order
to clear the DTC, register the compensation codes first, then turn the ignition switch to OFF and wait
for 30 seconds or more.

(n) Confirm the injection compensation code displayed on
the hand−held tester.
NOTICE:
Be careful not to register a wrong compensation code to
the ECM. If a wrong code is set to the ECM, rough idling or
engine rattling may result. In addition, it may become a
cause of engine failure or shorten the life of the engine.
HINT:
SThe code shown in the illustration is an example.
SIf a wrong compensation code was entered on the hand−
held tester, select the ”NO” button to correct the error
(Back to step [g]).
(o) Press the ”YES” button to set the code to the ECM.
(p) Wait until the next screen comes up.
