Procedure

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. 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.





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 terminals 59 and 43 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 terminals 59 and 43 is lower than 1.4V).
- The engine is started at the tank fuel temperature of warmer than 0°C (32°F) (where the voltage between the ECM terminal 60 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:
- The driving pattern outlined in *2 must be repeated at least 3 times.
Pattern 4:
- Tests are performed after the engine has been operated for at least 17 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.
*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: Operate the vehicle in the following driving pattern.
1) Decelerate vehicle to 0 km/h and let engine idle.
2) Repeat driving pattern shown below at least 10 times.
- During acceleration, hold the accelerator pedal as steady as possible. (The THROTL POS SEN value of CONSULT should be between 0.8 to 1.2V.)
3) Repeat steps 1 and 2 until the EGR system SRT is set.





*3: Checking the vehicle speed with CONSULT or GST is advised.
*4: The driving pattern may be omitted when "PURG FLOW P1447" is performed using the "DTC WORK SUPPORT" mode with CONSULT.
*5: The driving pattern may be omitted when "EVAP SML LEAK P0440" is performed using the "DTC WORK SUPPORT" mode with CONSULT.
*6: The driving pattern may be omitted when all the followings are performed using the "DTC WORK SUPPORT" mode with CONSULT.
- "EGR SYSTEM P0400"
- "EGR SYSTEM P1402"
*7: The driving pattern may be omitted when "EGRC-BPT/VLV P0402" is performed using the "DTC WORK SUPPORT" mode with CONSULT.
Suggested Transmission Gear Position for A/T Models.
Set the selector lever in the "D" position with the overdrive switch turned ON.
