DRIVE CYCLE G

1. Refuel the vehicle.
2. Leave the vehicle to stand for at least 5 hours with an ambient temperature of greater than 2°C.
3. Drive the vehicle for at least 20 minutes.
4. Switch the engine off.
5. Check that the fuel level is between 15% and 85 % full.
6. Connect a generic scan tool and check for fault codes.

CATALYST MONITOR

1. Start engine and bring to normal operating temperature > 75 °C (167 °F).
2. With the gear selector in Park or Neutral, hold the engine speed at 2500 rpm for 5 minutes.
3. Drive vehicle ensuring that vehicle speed exceeds 15 km/h (10 mph) and the engine speed exceeds 1500 rpm.
4. Stop the vehicle and check for any temporary DTCs.

MISFIRE MONITOR

1. Record flagged DTC(s) and accompanying DTC Monitor freeze frame(s) data.
