ON BOARD DIAGNOSTIC (OBD) SYSTEM
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.
4. Turn ignition switch ON.
5. Check permanent DTC. Refer to EC-542, "
Emission-related Diagnostic Information", “How to Display Per-
manent DTC Status”.
6. 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.
9. Turn ignition switch ON.
10. Turn ignition switch OFF and wait at least 10 seconds.
11. Turn ignition switch ON.
12. Use “PERMANENT DTC WORK SUPPORT” to drive the vehicle according to driving pattern B.
*1: When the same malfunction is de-
tected in two consecutive trips, MIL
will illuminate. *2: After experiencing Driving pattern B
and D, permanent DTC is erased. *3: Indication does not change unless
the ignition switch is turned from ON
to OFF twice even after experiencing
Driving pattern B or D.

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 driv ing 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.

< SERVICE INFORMATION >[MR18DE]
ON BOARD DIAGNOSTIC (OBD) SYSTEM
tified codes can be identified by using the CONSULT-II
I or GST. A DTC will be used as an example for how to
read a code.
A particular trouble code can be identified by the number of four-digit numeral flashes. The “zero” is indicated
by the number of ten flashes. The “A” is indicated by the number of eleven flash. The length of time the
1,000th-digit numeral flashes on and off is 1.2 seconds consisting of an ON (0.6-second) - OFF (0.6-second)
cycle. The 100th-digit numeral and lower digit numer als consist of a 0.3-second ON and 0.3-second OFF
cycle. A change from one digit numeral to another occurs at an interval of 1.0-second OFF. In other words, the
later numeral appears on the display 1.3 seconds after the former numeral has disappeared.
A change from one trouble code to another occu rs at an interval of 1.8-second OFF.
In this way, all the detected malfunctions are classi fied by their DTC numbers. The DTC 0000 refers to no mal-
function. (See EC-504
)
How to Erase Diagnostic Test Mode II (Self-diagnostic Results)
The DTC can be erased from the back-up memory in the ECM by depressing accelerator pedal.
Refer to "How to Erase Diagnostic Test Mode II (Self-diagnostic Results)".
• If the battery is disconnected, the DTC will be lost from the backup memory within 24 hours.
• Be careful not to erase the stored memo ry before starting trouble diagnoses.
OBD System Operation ChartINFOID:0000000006341721
RELATIONSHIP BETWEEN MIL, 1ST TRIP DTC, DTC, AND DETECTABLE ITEMS
• When a malfunction is detected for the first time, the 1st trip DTC and the 1st trip freeze frame data are
stored in the ECM memory.
• When the same malfunction is detected in two consec utive trips, the DTC and the freeze frame data are
stored in the ECM memory, and the MIL will come on. For details, refer to EC-541, "
Two Trip Detection
Logic".
• The MIL will go off after the vehicle is driven 3 time s (driving pattern B) with no malfunction. The drive is
counted only when the recorded driving pattern is met (as stored in the ECM). If another malfunction occurs
while counting, the counter will reset.
• The DTC and the freeze frame data will be stored until the vehicle is driven 40 times (driving pattern A) with-
out the same malfunction recurring (except for Misfire and Fuel Injection System). For Misfire and Fuel Injec-
tion System, the DTC and freeze frame data will be stored until the vehicle is driven 80 times (driving pattern
