OK: Self-diagnosis is carried out and the result is OK.
NG: Self-diagnosis is carried out and the result is NG.
—: Self-diagnosis is not carried out.
When all SRT related self-diagnoses show OK results in a single cycle (Ignition OFF-ON-OFF), the SRT will
indicate “CMPLT”.
→
Case 1 above
When all SRT related self-diagnoses show OK results through several different cycles, the SRT will indicate
“CMPLT” at the time the respective self-diagnoses have at least one OK result.
→
Case 2 above
If one or more SRT related self-diagnoses show NG results in 2 consecutive cycles, the SRT will also indicate
“CMPLT”.
→
Case 3 above
The table above shows that the minimum number of cycles for setting SRT as “INCMP” is the number one (1)
for each self-diagnosis (Case 1 & 2) or the number two (2) for one of self-diagnoses (Case 3). However, in
preparation for the state emissions inspection, it is unnecessary for each self-diagnosis to be executed twice
(Case 3) for the following reasons:
• The SRT will indicate “CMPLT” at the time the respective self-diagnoses have one (1) OK result.
• The emissions inspection requires “CMPLT” of the SRT only with OK self-diagnosis results.
• During SRT driving pattern, the 1st trip DTC (NG) is detected prior to “CMPLT” of SRT and the self-diagnosis
memory must be erased from the ECM after repair.
• If the 1st trip DTC is erased, all the SRT will indicate “INCMP”.
NOTE:
SRT can be set as “CMPLT” together with the DTC(s). Therefore, DTC check must always be carried out
prior to the state emission inspection even though the SRT indicates “CMPLT”.
DIAGNOSIS DESCRIPTION : Malfunction Indicator (MI)
INFOID:0000000006635106
• When detecting a DTC that affects exhaust gas, the exhaust emis-
sion-related control module transmits a malfunction indicator signal
to ECM via CAN communication line.
ECM prioritizes (MI: ON/blink) the signal received from the exhaust
emission-related control module and the ECM-stored DTC that
affects exhaust gas and transmits a malfunction indicator lamp sig-
nal to the combination meter via CAN communication line.
The combination meter turns ON or blinks the MI, according to the
signal transmitted from ECM, and alerts the driver of malfunction
detection.
• Control modules that a DTC of MI ON/Blink is stored (Control mod-
ule varies among DTCs.):
- ECM
- TCM
1.
The MI illuminates when ignition switch is turned ON (engine is not running).
NOTE:
Check the MI circuit if MI does not illuminate. Refer to
EC-789, "Component Function Check"
2.
When the engine is started, the MI should go off.
NOTE:
If MI remains ON or continues blinking, a DTC(s) that affects exhaust gas is detected. In this case, Selfdi-
agnosis is required for performing inspection and repair.

DIAGNOSIS SYSTEM (ECM)
The on board diagnostic system has the following functions.
BULB CHECK MODE
Description
This function allows damage inspection in the MI bulb (blown, open circuit, etc.).
Operation Procedure
1.
Turn ignition switch ON.
2.
The MI on the instrument panel should stay ON.
If it remains OFF, check MI circuit. Refer to
EC-789, "Component Function Check"
SRT STATUS MODE
Description
This function allows to read if ECM has completed the self-diagnoses of major emission control systems and
components. For SRT, refer to
EC-496, "DIAGNOSIS DESCRIPTION : System Readiness Test (SRT) Code"
.
Operation Procedure
1.
Turn ignition switch ON and wait 20 seconds.
2.
SRT status is indicated as shown blow.
• ECM continues to illuminate MI if all SRT codes are set.
• ECM blinks MI for about 10 seconds if all SRT codes are not set.
MALFUNCTION WARNING MODE
Description
In this function ECM turns on or blinks MI when it detects a malfunction in the emission control system compo-
nents and/or the powertrain control components (which affect vehicle emissions) to inform the driver that a
malfunction has been detected.
Operation Procedure
Diagnostic test mode
Function
Bulb check
MI can be checked.
SRT status
ECM can read if SRT codes are set.
Malfunction warning
If ECM detects a malfunction, it illuminates or blinks MI to inform the driver that a mal-
function has been detected.
Self-diagnostic results
DTCs or 1st trip DTCs stored in ECM can be read.
Accelerator pedal released position learning
ECM can learn the accelerator pedal released position. Refer to
Throttle valve closed position learning
ECM can learn the throttle valve closed position. Refer to
.
Idle air volume learning
ECM can learn the idle air volume. Refer to
.

1.
Turn ignition switch ON.
2.
Check that MI illuminates.
If it remains OFF, check MI circuit. Refer to
EC-789, "Component Function Check"
3.
Start engine and let it idle.
• For two trip detection logic diagnoses, ECM turns on MI when it detects the same malfunction twice in
the two consecutive driving cycles.
• For 1st trip detection logic diagnoses, ECM turns on MI when it detects a malfunction in one driving
cycle.
• ECM blinks MI when it detects a malfunction that may damage the three way catalyst (misfire).
SELF-DIAGNOSTIC RESULTS MODE
Description
This function allows to indicate DTCs or 1st trip DTCs stored in ECM according to the number of times MI is
blinking.
How to Set Self-diagnostic Results Mode
NOTE:
• It is better to count the time accurately with a clock.
• It is impossible to switch the diagnostic mode when an accelerator pedal position sensor circuit has a mal-
function.
• After ignition switch is turned off, ECM is always released from the “self-diagnostic results” mode.
1.
Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.
2.
Repeat the following procedure quickly five times within 5 seconds.
• Fully depress the accelerator pedal.
• Fully release the accelerator pedal.
3.
Wait 7 seconds, fully depress the accelerator pedal and keep it depressed for approx. 10 seconds until the
MI starts blinking.
NOTE:
Do not release the accelerator pedal for 10 seconds if MI starts blinking during this period. This blinking is
displaying SRT status and is continued for another 10 seconds.
4.
Fully release the accelerator pedal.
ECM has entered to “Self-diagnostic results” mode.
NOTE:
Wait until the same DTC (or 1st trip DTC) appears to completely confirm all DTCs.
How to Read Self-diagnostic Results
The DTC and 1st trip DTC are indicated by the number of blinks of the MI as shown below.
The DTC and 1st trip DTC are displayed at the same time. If the MI does not illuminate in diagnostic test mode
I (Malfunction warning), all displayed items are 1st trip DTCs. If only one code is displayed when the MI illumi-
nates in “malfunction warning” mode, it is a DTC; if two or more codes are displayed, they may be either DTCs

DIAGNOSIS SYSTEM (ECM)
or 1st trip DTCs. DTC No. is same as that of 1st trip DTC. These unidentified codes can be identified by using
the CONSULT-III or GST. A DTC will be used as an example for how to read a code.
A particular trouble code can be identified by the number of four-digit numeral flashes per the following.
The length of time the 1,000th-digit numeral flashes on and off is 1.2 seconds consisting of an ON (0.6-sec-
onds) - OFF (0.6-seconds) cycle.
The 100th-digit numeral and lower digit numerals consist of a 0.3-seconds ON and 0.3-seconds OFF cycle.
A change from one digit numeral to another occurs at an interval of 1.0-second OFF. In other words, the later
numeral appears on the display 1.3 seconds after the former numeral has disappeared.
A change from one trouble code to another occurs at an interval of 1.8-seconds OFF.
In this way, all the detected malfunctions are classified by their DTC numbers. The DTC 0000 refers to no mal-
function. Refer to
How to Erase Self-diagnostic Results
By performing this procedure, ECM memory is erased and the following diagnostic information is erased as
well.
• Diagnostic trouble codes
• 1st trip diagnostic trouble codes
• Freeze frame data
• 1st trip freeze frame data
• System readiness test (SRT) codes
• Test values
NOTE:
Also, if a battery terminal is disconnected, ECM memory is erased and the diagnostic information as listed
above is erased. (The amount of time required for erasing may vary from a few seconds to several hours.)
1.
Turn ignition switch OFF and wait at least 10 seconds.
2.
Turn ignition switch ON.
3.
Turn ignition switch OFF and wait at least 10 seconds.

VALUES ON THE DIAGNOSIS TOOL
Remarks:
• Specification data are reference values.
• Specification data are output/input values which are detected or supplied by the ECM at the connector.
*Specification data may not be directly related to their components signals/values/operations.
i.e. Adjust ignition timing with a timing light before monitoring IGN TIMING, because the monitor may show the
specification data in spite of the ignition timing not being adjusted to the specification data. This IGN TIMING
monitors the data calculated by the ECM according to the signals input from the camshaft position sensor and
other ignition timing related sensors.
