Mode 6 Data

DRIVING PATTERN
- The time required for each diagnosis varies with road surface conditions, weather, attitude, 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 - 4.3 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 43 is lower than 1 .4 V).
- 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 KPH (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 KPH (56 MPH) again.
*2: Operate the vehicle in the following driving pattern.

1. Decelerate vehicle to 0 KPH 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 1.2 V)




3. Repeat steps 1 and 2 until the EGR system SRT is set.

*3: 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.

TEST VALUE AND TEST LIMIT (GST ONLY - NOT APPLICABLE TO CONSULT)
The following is the information specified in Mode 6 of SAE J1979.
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.
Items for which these data (test value and test limit) are displayed are the same as SRT code items (30 test items).
These data (test value and test limit) are specified by Test ID (TID) and Component ID (CID) and can be displayed on the GST screen.

EMISSION-RELATED DIAGNOSTIC INFORMATION ITEMS
*1: In Diagnostic Test Mode II (Self-diagnostic results). These numbers are controlled by NISSAN.
*2: These numbers are prescribed by SAE J2012.
*3: These are not displayed with GST.
*4: 1st trip DTC No. is the same as DTC No.

NOTE: Regarding R50 models, "-B1" and "BK1" indicate right bank and "-B2" and "Bk2" indicate left bank.
