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)]

1.

CHECK DTC

Check DTC.
Is any DTC detected?

YES

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

EC-542, "DTC Index"

.

NO

>> GO TO 2.

2.

CHECK SRT STATUS

With CONSULT

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

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-25, "Description"

.

3. Check DTC.
Is any DTC detected?

YES

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

EC-542, "DTC Index"

.

NO

>> GO TO 10.

4.

PERFORM ROAD TEST

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

EC-25, "Description"

.

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

EC-26, "SRT Set Driving

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 

EC-522, "Reference Value"

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.

HOW TO ERASE PERMANENT DTC

Description

INFOID:0000000010094794

OUTLINE

When a DTC is stored in ECM

When a DTC is stored in ECM and MIL is ON, a permanent DTC is erased with MIL shutoff if the same mal-

function is not detected after performing the driving pattern for MIL shutoff three times in a raw.

When a DTC is not stored in ECM

The erasing method depends on a permanent DTC stored in ECM. Refer to the following table.

NOTE:

If the applicable permanent DTC includes multiple groups, perform the procedure of Group B first. If the per-

manent DTC is not erased, perform the procedure of Group A.

×: Applicable —: Not applicable

*: For group, refer to 

EC-542, "DTC Index"

.

PERMANENT DTC ITEM

For permanent DTC items, MIL turns ON. Refer to 

EC-542, "DTC Index"

.

*1: When the same malfunction is de-

tected in two consecutive trips, MIL 
will illuminate.

*2: MIL will turn off after vehicle is driven 

3 times (driving pattern B) without 
any malfunctions.
