OBD II Drive Cycle Procedure

NOTE:
- Disconnecting the battery will reset the memory. Do not disconnect the battery during and/or after this procedure.
- Vehicle speed and engine speed detected by the PCM may differ from that indicated by the speedometer and the tachometer. Check the vehicle speed and engine speed during driving mode by using the New Generation Star (NGS) tester.
- It the OBD II system check is not completed while the drive cycle procedure is carried out, the following cause is guessed.
1. The OBD II system detects the malfunction.
2. The drive cycle procedure is not completed correctly.





MODE 1
1. Start the engine and warm it up completely.
2. Verify that all electrical loads (headlight, blower motor and rear window defroster) and A/C loads are off.
3. Verify that the initial ignition timing and the initial idle speed are within the specification.
4. If not as specified, adjust the ignition timing and idle speed.
5. Verify that terminals TEN and GND of the data link connector are not connected.
6. Carry out no-load racing at the specified speed for each model. Race the engine for more than 15 seconds at each time. Refer to the following engine speed table for engine speed.




7. Idle the engine for more than 20 seconds with the electric cooling fan stopped.




MODE 2
1. Start the engine and warm it up completely.
2. Verify that all electrical loads (headlight, blower motor and rear window defroster) and A/C load are off.

NOTE: Driving mode before the constant speed driving is not specified.

3. Drive the vehicle at the constant speed of 81-96 km/h (50-60 mph) for 60 seconds. (MT: 5th gear, AT: D range)




MODE3
1. Start the engine and warm it up completely.
2. Verify that all electrical loads (headlight, blower motor and rear window defroster) and A/C load are off.
3. Drive the vehicle at the constant speed of above 65 km/h (40 mph) for 60 seconds after the above 300 seconds from engine start. (MT: 4th or 5th gear, AT: D range)
4. Drive the vehicle at the constant speed 48-81 km/h (3-50 mph) for 180 seconds. (MT: 4th gear, AT: D range)

NOTE: Driving mode before the constant speed driving is not specified.
