How to Display SRT Status
WITH CONSULT-III
Selecting “SRT STATUS” in “DTC CONFIRMATION” mode with CONSULT-III.
For items whose SRT codes are set, “CMPLT” is displayed on the CONSULT-III screen; for items whose SRT
codes are not set, “INCMP” is displayed.
NOTE:
• Though displayed on the CONSULT-III screen, “HO2S HTR” is not SRT item.
• “SRT STATUS” provides the presence or absence of permanent DTCs stored in ECM memory.

Selecting Service $01 with GST (Generic Scan Tool)
NO TOOLS
A SRT code itself cannot be displayed, however SRT status can.
1. Turn ignition switch ON and wait 20 seconds.
2. SRT status is indicated as shown below.
• When all SRT codes are set, MIL illuminates continuously.

• When any SRT codes are not set, MIL will blink periodically for 10 seconds.
How to Set SRT Code
To set all SRT codes, self-diagnosis for the items indicated above must be performed one or more times. Each
diagnosis may require a long period of actual driving under various conditions.
WITH CONSULT-III
Perform corresponding DTC Confirmation Procedure one by one based on Performance Priority in the table
on "SRT Item".
WITHOUT CONSULT-III
The most efficient driving pattern in which SRT codes can be properly set is explained below. The driving pat-
tern should be performed one or more times to set all SRT codes.

Driving Pattern
• The time required for each diagnosis varies with road surface conditions, weather, altitude, individual driving
habits, etc.
Zone A refers to the range where the time, required for the diagnosis under normal conditions*, is the short-
est.
Zone B refers to the range where the diagnosis can still be performed if the diagnosis is not completed within
zone A.
*: Normal conditions refer to the following:

• Sea level
• Flat road
• Ambient air temperature: 20 - 30
°
C (68 - 86
°
F)
• Diagnosis is performed as quickly as possible under normal conditions.
Under different conditions [For example: ambient air temperature other than 20 - 30
°
C (68 - 86
°
F)], diagno-
sis may also be performed.
Pattern 1:
•
The engine is started at the engine coolant temperature of
−
10 to 35
°
C (14 to 95
°
F)
(where the voltage between the ECM terminal 73 and ground is 3.0 - 4.3V).
•
The engine must be operated at idle speed until the engine coolant temperature is greater than 70
°
C
(158
°
F) (where the voltage between the ECM terminal 73 and ground is lower than 1.4V).
•
The engine is started at the fuel tank temperature of warmer than 0
°
C (32
°
F) (where the voltage
between the ECM terminal 107 and ground is less than 4.1V).
Pattern 2:
• When steady-state driving is performed again even after it is interrupted, each diagnosis can be conducted.
In this case, the time required for diagnosis may be extended.
Pattern 3:
• Operate vehicle following the driving pattern shown in the figure.
• Replace the accelerator pedal during decelerating vehicle speed
from 90km/h (56MPH) to 0km/h (0MPH).
Pattern 4:
• Operate vehicle, following the driving pattern shown in the figure.
- Drive the vehicle in a proper gear at 60 km/h (38 MPH) and main-
tain the speed.
- Release the accelerator pedal fully at least 5 seconds.
- Repeat the above two steps at least 5 times.
Pattern 5:
• The accelerator pedal must be held very steady during steady-state driving.
• If the accelerator pedal is moved, the test must be conducted all over again.
*1: Depress the accelerator pedal until vehicle speed is 90 km/h (56 MPH), then release the accelerator pedal
and keep it released for more than 10 seconds. Depress the accelerator pedal until vehicle speed is 90 km/h
(56 MPH) again.
*2: Checking the vehicle speed with GST is advised.
Suggested Transmission Gear Position
Set the selector lever in the D position with the overdrive switch turned ON.
PERMANENT DIAGNOSTIC TROUBLE CODE (PERMANENT DTC)
Permanent DTC is defined in SAE J1979/ISO 15031-5 Service $0A.
ECM stores a DTC issuing a command of turning on MIL as a permanent DTC and keeps storing the DTC as
a permanent DTC until ECM judges that there is no presence of malfunction.

ECM
Permanent DTCs cannot be erased by using the Erase function of CONSULT-III or Generic Scan Tool (GST)
and by disconnecting the battery to shut off power to ECM. This prevents a vehicle from passing the state
emission inspection without repairing a malfunctioning part.
When not passing the state emission inspection due to more than one permanent DTC, permanent DTCs
should be erased, referring to this manual.
NOTE:
• The important items in state emission inspection are that MIL is not ON, SRT test items are set, and perma-
nent DTCs are not included.
• Permanent DTCs do not apply for regions that permanent DTCs are not regulated by law.
Permanent DTC Item
For permanent DTC items, MIL turns ON. Refer to
EC-464, "Emission-related Diagnostic Information"
, “EMIS-
SION-RELATED DIAGNOSTIC INFORMATION ITEMS”.
Permanent DTC Set Timing
The setting timing of permanent DTC is stored in ECM with the lighting of MIL when a DTC is confirmed.
Permanent DTC Service Procedure
How to Display Permanent DTC Status
WITH CONSULT-III
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.
4. Turn ignition switch ON.
5. Select “PERMANENT DTC STATUS” in “DTC & SRT CONFIRMATION” mode with CONSULT-III.
NOTE:
Permanent DTCs stored in ECM memory are displayed on the CONSULT-III screen to show if a driving
pattern required for erasing permanent DTCs is complete (CMPLT) or incomplete (INCMP).

Since the “PERMANENT DTC STATUS” screen displays the previous trip information, repeat the
following twice to update the information: “Ignition switch OFF”, “Wait for more than 10 seconds”
and “Ignition switch ON”.
WITH GST
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.
4. Turn ignition switch ON.
5. Select Service $0A with GST (Generic Scan Tool).
TEST VALUE AND TEST LIMIT
The following is the information specified in Service $06 of SAE J1979/ISO 15031-5.
The test value is a parameter used to determine whether a system/circuit diagnostic test is OK or NG while
being monitored by the ECM during self-diagnosis. The test limit is a reference value which is specified as the
maximum or minimum value and is compared with the test value being monitored.
These data (test value and test limit) are specified by On Board Monitor ID(OBDMID), Test ID (TID), Unit and
Scaling ID and can be displayed on the GST screen.
The items of the test value and test limit will be displayed with GST screen which items are provided by the
ECM. (e.g., if bank 2 is not applied on this vehicle, only the items of bank 1 are displayed)
