Without CONSULT-II

The most efficient driving pattern in which SRT codes can be properly set is explained in Fig 1 . 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 121 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 121 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 92 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:

• 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 (0 MPH) and let engine idle.
2. Repeat driving pattern shown at right at least 10 times.

• During acceleration, hold the accelerator pedal as steady as possible. 

*3: Checking the vehicle speed with GST is advised.

Suggested Transmission Gear Position 

Set the selector lever in the D position.
