HOW TO SET SRT CODE

Description

INFOID:0000000009481232

OUTLINE

In order to set all SRTs, the self-diagnoses as in the “SRT ITEM” table must have been performed at least

once. Each diagnosis may require actual driving for a long period of time under various conditions.

SRT ITEM

The table below shows required self-diagnostic items to set the SRT to “CMPLT”.

• *1: Though displayed on the CONSULT screen, “HO2S HTR” is not SRT item.

• *2: If completion of several SRTs is required, perform driving patterns (DTC confirmation procedure), one by

one based on the priority for models with CONSULT.

SRT SERVICE PROCEDURE

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.

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”.

HOW TO SET SRT CODE

*: Normal conditions

- Sea level

- Flat road

- Ambient air temperature: 20 – 30

°C (68 – 86°F)

NOTE:

Diagnosis is performed as quickly as possible under normal conditions. However, under other conditions,

diagnosis may also be performed. [For example: ambient air temperature other than 20 – 30

°C (68 – 86°F)]

Work Procedure

INFOID:0000000009481234

1.

CHECK DTC

Check DTC.
Is any DTC detected?

YES

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

EC-543, "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-515, "On Board Diagnosis Function"

.

With GST

Select Service $01 with GST.
Is SRT code(s) set?

YES

>> GO TO 11.

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-595, "Description"

.

3. Check DTC.
Is any DTC detected?

YES

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

EC-543, "DTC Index"

.

NO

>> GO TO 10.

4.

PERFORM ROAD TEST

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

EC-595, "Description"

.

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

EC-596, "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

Refer to
