How to Set SRT Code

To set all SRT codes, self-diagnoses for the SRT items must be performed one or more times. Refer to "DIAGNOSIS DESCRIPTION ", "SYSTEM READINESS TEST (SRT) CODE", "SRT Item"  .

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 pattern 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 shortest.

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)], diagnosis 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 38 and ground is 3.0 - 4.3 V). 

• 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 38 and ground is lower than 1.4 V). 
• The engine is started at the fuel tank temperature of warmer than 0°C (32°F) (where the voltage between the ECM terminal 43 and ground is less than 4.1 V). 

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.
• Release the accelerator pedal during decelerating vehicle speed from 90 km/h (56 MPH) to 0 km/h (0 MPH).

  Pattern 4:

• The accelerator pedal must be held very steady during steady state driving.
• If the accelerator pedal is moved, the test must be conducted 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 for Models

Set the selector lever in the D position.

Suggested Upshift Speeds for M/T Models

Shown below are suggested vehicle speeds for shifting into a higher gear. These suggestions relate to fuel economy and vehicle performance. Actual upshift speeds will vary according to road conditions, the weather and individual driving habits.

	For normal acceleration in low altitude areas [less than 1, 219 m (4, 000 ft)]:		For quick acceleration in low altitude areas and high altitude areas [over 1, 219 m (4, 000 ft)]:
Gear change	ACCEL shift position [km/h (MPH)]	CRUISE shift point [km/h (MPH)]	km/h (MPH)
1st to 2nd	15 (9)	21 (13)	15 (9)
2nd to 3rd	25 (16)	38 (24)	30 (19)
3rd to 4th	40 (25)	55 (34)	45 (28)
4th to 5th	45 (28)	74 (46)	50 (31)
