NOTE:
• Drive the vehicle according to only driving patterns indicating “INCMP” in driving patterns B and D on the

“PERMANENT DTC STATUS” screen.

• When experiencing both driving pattern B and D during the same trip, the experience of driving pattern D is

counted by priority.

1.

Turn ignition switch OFF and wait at least 10 seconds.

2.

Turn ignition switch ON.

3.

Turn ignition switch OFF and wait at least 10 seconds.

Start engine and warm it up to normal operating temperature.

7.

Drive the vehicle according to driving pattern D.

CAUTION:

• Always drive at a safe speed.
• Never erase self-diagnosis results.
• If self-diagnosis results are erased during the trip of driving pattern B or D, the counter of driving

pattern B or D is reset.

• If self-diagnosis results are erased during the trip of driving pattern B or D, an experience of driv-

ing pattern B and D during the same trip is not counted up.

8.

Turn ignition switch OFF and wait at least 10 seconds.

and D, permanent DTC is erased.

*3:

Indication does not change unless 
the ignition switch is turned from ON

DRIVING PATTERN

Driving Pattern B

Driving pattern B means a trip satisfying the following conditions.
• Engine speed reaches 400 rpm or more.
• Water temperature reaches 70

°

C (158

°

F) or more.

• Vehicle speed of 70 – 120 km/h (44 – 75 MPH) is maintained for 60 seconds or more under the control of

closed loop.

• Vehicle speed of 30 – 60 km/h (19 – 37 MPH) is maintained for 10 seconds or more under the control of

closed loop.

• Under the closed loop control condition, the following state reaches 12 seconds or more in total: Vehicle

speed of 4 km/h (2 MPH) or less with idling condition.

• The state of driving at 10 km/h (7 MPH) or more reaches 10 minutes or more in total.
• A lapse of 22 minutes or more after engine start.

CAUTION:

Always drive at a safe speed.
NOTE:
• Drive the vehicle at a constant velocity.
• When the same malfunction is detected regardless of driving conditions, reset the counter of driving pattern

B.

• When the above conditions are satisfied without detecting the same malfunction, reset the counter of driving

pattern B.

Driving Pattern D

Driving pattern D means operating vehicle as per the following.
• The state of driving at 40 km/h (25 MPH) reaches 300 seconds or more in total.
• Idle speed lasts 30 seconds or more.
• A lapse of 600 seconds or more after engine start.

CAUTION:

Always drive at a safe speed.
NOTE:
• When the same malfunction is detected regardless of driving conditions, reset the counter of driving pattern

D.

• When the above conditions are satisfied without detecting the same malfunction, reset the counter of driving

pattern D.

Test Value and Test Limit

INFOID:0000000005589003

The following is the information specified in Service $06 of SAE J1979/ISO 15031-5.
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.
These data (test value and test limit) are specified by On Board Monitor ID (OBDMID), Test ID (TID), Unit and
Scaling ID and can be displayed on the GST screen.
