If a vehicle has failed the state emissions inspection due to one or more SRT items indicating “INCMP”, review
the flowchart diagnostic sequence, referring to the following flowchart.

HOW TO SET SRT CODE

Always drive the vehicle in safe manner according to traffic conditions and obey all traffic laws.

*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.
• The time required for each diagnosis varies with road surface conditions, weather, altitude, individual driving

habits, etc.

• “Zone A” is the fastest time where required for the diagnosis under normal conditions*. If the diagnosis is not

completed within “Zone A”, the diagnosis can still be performed within “Zone B”.

Work Procedure

INFOID:0000000010986286

1.

CHECK DTC

Check DTC.
Is any DTC detected?

YES

>> Repair malfunction(s) and erase DTC. Refer to 

EC-517, "DTC Index"

.

NO

>> GO TO 2.

2.

CHECK SRT STATUS

With CONSULT

Select “SRT STATUS” in “DTC & SRT CONFIRMATION” mode with CONSULT.

Without CONSULT

Perform “SRT status” mode with 

EC-488, "On Board Diagnosis Function"

.

With GST

Select Service $01 with GST.

Is SRT code(s) set?

YES

>> END

NO-1

>> With CONSULT: GO TO 3.

NO-2

>> Without CONSULT: GO TO 4.

3.

DTC CONFIRMATION PROCEDURE

1.

Select “SRT WORK SUPPORT” in “DTC & SRT CONFIRMATION” mode with CONSULT.

2.

For SRT(s) that is not set, perform the corresponding “DTC CONFIRMATION PROCEDURE” according to
the “Performance Priority” in the “SRT ITEM” table. Refer to 

EC-560, "Description"

.

3.

Check DTC.

Is any DTC detected?

YES

>> Repair malfunction(s) and erase DTC. Refer to 

EC-517, "DTC Index"

.

NO

>> GO TO 10.

4.

PERFORM ROAD TEST

• Check the “Performance Priority” in the “SRT ITEM” table. Refer to 

EC-560, "Description"

.

• Perform the most efficient SRT set driving pattern to set the SRT properly. Refer to 

EC-561, "SRT Set Driv-

ing Pattern"

.

In order to set all SRTs, the SRT set driving pattern must be performed at least once.

>> GO TO 5.

5.

PATTERN 1

1.

Check the vehicle condition;

-

Engine coolant temperature is 

−

10 to 35

°

C (14 to 95

°

F).

-

Fuel tank temperature is more than 0

°

C (32

°

F).

2.

Start the engine.

3.

Keep engine idling until the engine coolant temperature is greater than 70

°

C (158

°

F)

NOTE:
ECM terminal voltage is follows;
• Engine coolant temperature
-

−

10 to 35

°

C (14 to 95

°

F): 3.0 – 4.3 V

- 70

°

(158

°

F): Less than 4.1 V

• Fuel tank temperature: Less than 1.4 V

>> GO TO 6.

6.

PATTERN 2

1.

Drive the vehicle. And 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.

2.

Depress the accelerator pedal until vehicle speed is 90 km/h (56 MPH) again

NOTE:
• Checking the vehicle speed with GST is advised.
• 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.

>> GO TO 7.

7.

PATTERN 3

• Operate vehicle following the driving pattern shown in the figure.
- Release the accelerator pedal during deceleration of vehicle speed

from 90 km/h (56 MPH) to 0 km/h (0 MPH).

>> GO TO 8.

8.

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.

>> GO TO 9.

9.

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 again.

>> GO TO 10.

10.

CHECK SRT STATUS

With CONSULT

Select “SRT STATUS” in “DTC & SRT CONFIRMATION” mode with CONSULT.
