HOW TO SET SRT CODE

-

−10 to 35°C (14 to 95°F): 3.0 - 4.3 V

- 70

°(158°F): Less than 1.4 V

• Fuel tank temperature: Less than 4.1 V

Refer to 

EC-61, "ECM Terminal and Reference Value"

.

>> 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-

tainthe 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.

10.

CHECK SRT STATUS

WITH CONSULT-III

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

WITHOUT CONSULT-III

Perform “SRT status” mode with 

EC-44, "DIAGNOSIS DESCRIPTION : System Readiness Test (SRT) Code"

.

WITH GST

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

TROUBLE DIAGNOSIS - SPECIFICATION VALUE

DTC/CIRCUIT DIAGNOSIS

TROUBLE DIAGNOSIS - SPECIFICATION VALUE

Description

INFOID:0000000006158543

The specification (SP) value indicates the tolerance of the value that is displayed in “SPEC” of “DATA MONI-

TOR” mode with CONSULT-III during normal operation of the Engine Control System. When the value in

“SPEC” of “DATA MONITOR” mode is within the SP value, the Engine Control System is confirmed OK. When

the value in “SPEC” of “DATA MONITOR” mode is NOT within the SP value, the Engine Control System may

have one or more malfunctions.

The SP value is used to detect malfunctions that may affect the Engine Control System, but will not light the

MIL.

The SP value will be displayed for the following three items:

• B/FUEL SCHDL (The fuel injection pulse width programmed into ECM prior to any learned on board correc-

tion)

• A/F ALPHA-B1/B2 (The mean value of air-fuel ratio feedback correction factor per cycle)

• MAS A/F SE-B1 (The signal voltage of the mass air flow sensor)

Testing Condition

INFOID:0000000006158544

• Vehicle driven distance: More than 5,000 km (3,107 miles)
• Barometric pressure: 98.3 - 104.3 kPa (1.003 - 1.064 kg/cm

2

, 14.25 - 15.12 psi)

• Atmospheric temperature: 20 - 30

°C (68 - 86°F)

• Engine coolant temperature: 75 - 95

°C (167 - 203°F)

• Engine speed: Idle

• Transmission: Warmed-up

- After the engine is warmed up to normal operating temperature, drive vehicle until “ATF TEMP SE 1” (A/T

fluid temperature sensor signal) indicates more than 60

°C (140°F).

• Electrical load: Not applied

- Rear window defogger switch, air conditioner switch, lighting switch are OFF. Steering wheel is straight

ahead.

Inspection Procedure

INFOID:0000000006158545

NOTE:

Perform “SPEC” in “DATA MONITOR” mode in maximum scale display.
1. Perform 

EC-110, "Basic Inspection"

.

2. Confirm that the testing conditions indicated above are met.
3. Select “B/FUEL SCHDL”, “A/F ALPHA-B1”, “A/F ALPHA-B2” and “MAS A/F SE-B1” in “SPEC” of “DATA

MONITOR” mode with CONSULT-III.

4. Make sure that monitor items are within the SP value.
5. If NG, go to 

EC-129, "Diagnosis Procedure"

.
