ON BOARD DIAGNOSIS LOGIC

DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE

CAUTION: Always drive vehicle at a safe speed.

NOTE: If "DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE" has been previously conducted, always turn ignition switch "OFF" and wait at least 5 seconds before conducting the next test.

TESTING CONDITION: Always drive vehicle on a level road to improve accuracy of test.

After the repair, perform the following procedure to confirm the malfunction is eliminated.








With CONSULT
1. Turn ignition switch "ON" and select "DATA MONITOR" mode for "ENGINE" with CONSULT.
2. Start engine.
3. Accelerate vehicle to a speed of more than 10 KPH (6 MPH) with "D" position (OD "ON").
4. Release accelerator pedal completely with "D" position (OD "OFF").

With GST
1. Start engine.
2. Drive vehicle under the following conditions:
Selector lever in "D", overdrive control switch in "ON" or "OFF" position and vehicle speed higher than 10 KPH (6 MPH).
3. Select "MODE 7" with GST.

Without Scan Tools
1. Start engine.
2. Drive vehicle under the following conditions:
Selector lever in "D" overdrive control switch in "ON" or "OFF" position and vehicle speed higher than 10 KPH (6 MPH).
