1.

Turn ignition switch ON and wait 20 seconds.

2.

SRT status is indicated as shown below.
• When all SRT codes are set, MIL lights up continuously.
• When any SRT codes are not set, MIL will flash periodically for 10 seconds.

How to Set SRT Code

To set all SRT codes, self-diagnosis for the items indicated above must be performed one or more times. 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 on the next page. The
driving pattern should be performed one or more times to set all SRT codes.

ON BOARD DIAGNOSTIC (OBD) SYSTEM

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 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.

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 73 and ground is 3.0 - 4.3V).

• 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 73 and ground is lower than 1.4V).

• The engine is started at the fuel tank temperature of warmer than 0

°

C (32

°

F) (where the voltage

between the ECM terminal 107 and ground is less than 4.1V). 

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 all

over 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 A/T Models
Set the selector lever in the D position with the overdrive switch turned ON.
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.

Suggested Maximum Speed in Each Gear
Downshift to a lower gear if the engine is not running smoothly, or if you need to accelerate.
Do not exceed the maximum suggested speed (shown below) in any gear. For level road driving, use the high-
est gear suggested for that speed. Always observe posted speed limits and drive according to the road condi-
tions to ensure safe operation. Do not over-rev the engine when shifting to a lower gear as it may cause
engine damage or loss of vehicle control.

TEST VALUE AND TEST LIMIT (GST ONLY — NOT APPLICABLE TO CONSULT-III)

The following is the information specified in Service $06 of SAE J1979/ISO 15031-5.
The test value is a parameter used to determine whether a system/circuit diagnostic test is OK or NG while
being monitored by the ECM during self-diagnosis. The test limit is a reference value which is specified as the
maximum or minimum value and is compared with the test value being monitored.
These data (test value and test limit) are specified by On Board Monitor ID (OBDMID), Test ID (TID), Unit and
Scaling ID and can be displayed on the GST screen.
The items of the test value and test limit will be displayed with GST screen which items are provided by the
ECM. (eg., if bank 2 is not applied on this vehicle, only the items of bank 1 are displayed)
