How to Display System Readiness Codes
CONSULT1. Selecting "SRT" in "SRT-OBT TEST VALUE" mode with CONSULT
For items whose SRT codes are set, a "CMPLT" is displayed on the CONSULT screen; for items whose SRT codes are not set, "INCMP" is displayed.

2. Selecting Mode I with GST (Generic Scan Tool)
HOW TO SET SRT CODE
To set all SRT codes, all diagnoses indicated on the previous page must be performed at least two times. Each diagnosis may require a long period of actual driving under various conditions. The most efficient driving pattern in which SRT codes can be properly set is explained on the next page. This type of driving pattern should be performed two times or more to set all SRT codes.
Self-diagnoses of "EVAP PURGE FLOW/MON", "EVAP (SMALL LEAK)" and "EGRC-BPT VALVE" are not provided for Y32 models. Using driving patterns I through 3 are adequate.
DRIVING PATTERN
*1: Depress the accelerator pedal until vehicle speed is 80 km/h (50 MPH). then release the accelerator pedal. Depress the accelerator pedal until vehicle speed is 80 km/h (50 MPH) again.
*2: Operate the vehicle in the driving pattern shown in the image.
*3: The driving pattern may be omitted when EVAP (SMALL LEAK) checks are performed using the FUNCTION TEST mode of CONSULT.
- 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 it the diagnosis is not completed within zone A.
*: Normal conditions refer to the following:
- Sea level
- Flat road
- Ambient temperature: 20 - 30°C (68 - 86°F)
- Diagnosis is performed as quickly as possible under normal conditions.
Under different conditions (For example: ambient temperature is 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 terminals (59) and (25) 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 terminals (59) and (25) is lower than 1.4 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:
- The driving pattern outlined in *2 must be repeated at least 3 times.
On M/T models, shift gears following "Suggested upshift speeds" schedule at right.
Pattern 4:
- Tests are performed alter the engine has been operated for at least 12 minutes.
- 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.
- The driving pattern must be started from pattern 1 and performed in the numerical order of the pattern.
- Any driving condition without stopping engine is permitted between the patterns, for example, between the pattern 1 and pattern 2.
SUGGESTED TRANSMISSION GEAR POSITION FOR A/T MODELS
Set the selector lever in the "D" position with the overdrive on-off 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.
For normal acceleration in low altitude areas less than 1,219 m (4,000 ft):
Gear change Accel km/h(MPH) / Cruise km/h(MPH)
1st to 2nd 24(15) / 24(15)
2nd to 3rd 40(25) / 29(18)
3rd to 4th 58(36) / 48(30)
4th to 5th 64(40) / 63(39)
For quick acceleration in low altitude areas and high altitude areas over 1,219 m (4,000 ft):
Gear change km/h / (MPH)
1st to 2nd 24 / (15)
2nd to 3rd 40 / (25)
3rd to 4th 64 / (40)
4th to 5th 72 / (45)
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 highest gear suggested for that speed. Always observe posted speed limits, and drive according to the road conditions, which will 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.
Gear km/h / (MPH)
1st 50 / (30)
2nd 95 / (60)
3rd 145 / (90)
4th - / -
5th - / -
