< BASIC INSPECTION >

[MRA8DE]

HOW TO SET SRT CODE

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.

• "EGR/VVT SYSTEM" written in the figure is not applicable to the vehicle.

Work Procedure

INFOID:0000000009758414

EC-63, "On Board Diagnosis Function"

.

With GST

Select Service $01 with GST.

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” using 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-145, "Description"

.

3. Check DTC.
Is any DTC detected?

YES

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

EC-94, "DTC Index"

.

NO

>> GO TO 9.

4.

PERFORM ROAD TEST

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

EC-145, "Description"

.

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

EC-146, "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;

>> 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.

CHECK SRT STATUS

With CONSULT

Select “SRT STATUS” in “DTC & SRT CONFIRMATION” using CONSULT.

WITHOUT CONSULT

Perform “SRT status” mode with 

EC-63, "On Board Diagnosis Function"

.

HOW TO ERASE PERMANENT DTC

Description

INFOID:0000000009758415

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-94, "DTC Index"

.

PERMANENT DTC ITEM

For permanent DTC items, MIL turns ON. Refer to 

EC-94, "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.
