OBDII Drive Mode Procedure

NOTE
- Disconnecting the battery will reset memory. Do not disconnect the battery during and 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 SST (NGS).
- If the OBD-II system check is not completed while the drive mode procedure is carried out, the following cause is guessed.
1. The OBD-II system detects the malfunction.
2. The drive mode procedure is not completed correctly.




OBD II Drive Mode Procedure Flow Chart

*Verify that all of the following condition are satisfied:
- Engine coolant temperature is 0 - 35°C {32 - 95°F}.
- Intake air temperature is 10°C {50 - 140°F}.
- Barometric pressure is 72.0 kPa [540 mmHg, 21.3 inHg] or higher.
- Fuel gauge needle points within 15 - 85%.
If any of these conditions is not satisfied, you can perform Drive Mode 3. Therefore, you must go to the following steps first.

MODE I
1. Start the engine and warm it up completely.
2. Verify that all electrical loads (head light, 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. Is not as specified, adjust the ignition timing and idle speed.
5. Verify that terminals TEM and GND of the data link connector are not connected.




6. Carry out no-load racing at the specified speed. Race the engine for more than 15 seconds at each time.
7. Idle the engine for more than 20 seconds with the electric cooling fan stopped.

MODE 2 (For EGR system check)
1. Start the engine and warm it up completely.
2. Verify that all electrical loads (head light, 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 (V: Refer to table below) for one minute.

MODE 3 (For OXYGEN SENSOR HEATER, OXYGEN SENSOR and CATALYST check)
1. Start the engine and warm it up completely.
2. Verify that all electrical loads (head light, blower motor and rear window defroster) and A/C load are off.
3. Drive the vehicle at the constant speed (V1: Refer to table below) for one minutes after the above five minutes from engine start.




4. Drive the vehicle at the constant speed (V2: Refer to table below) for three minutes (T3).

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

MODE 4 (For Evaporative purge system [Leak monitor] check)
1. Verify that all following conditions are satisfied.
- Engine coolant temperature is 0 - 35°C {32 - 95°F}.
- Intake air temperature is 10 - 60°C {50 - 140°F}.
- Barometric pressure is 72.0 kPa {540 mmHg, 21.3 inHg} or higher.
- Fuel gauge needle points within 15 - 85%
2. Start the engine and race it at 3,500 rpm for 200 seconds to warm it up completely.
3. Within 240 seconds after engine start, start the vehicle and accelerate to 65 - 96 km/h {45 - 60 mph} in approximately 20 seconds.




4. Drive the vehicle at the constant speed of 65 - 96 km/h {40 - 60 mph} till 360 seconds after engine start.
