5. DRIVE CYCLE D
Drift Diagnosis
1) Check that the engine coolant temperature at engine start is 30°C (86°F) or less.
2) Check that the battery voltage is more than 10.9 V and that more than 9.6 2 (2.5 US gal, 2.1 Imp gal) of
fuel remains.
3) Start the engine, and check that the engine coolant temperature increases over 10°C (50°F), and reaches
75°C (167°F) or more, when the engine is warmed up.
4) After the engine has reached the state of procedure 3), idle the engine for more than 120 seconds.
Stuck Diagnosis
1) Check that the battery voltage is over 10.9 V.
2) Perform the clear memory mode.
3) Drive for approximately 50 2 (13.2 US gal, 11 Imp gal) of fuel.
NOTE:
•It is acceptable to drive the vehicle intermittently.
•Do not disconnect the battery terminals while diagnosing. (Data will be cleared by disconnecting the bat-
tery terminals.)
6. DRIVE CYCLE E
1) Check that the battery voltage is over 10.9 V.
2) Perform the clear memory mode.
3) Drive for approximately 30 2 (7.9 US gal, 6.6 Imp gal) of fuel.
NOTE:
•It is acceptable to drive the vehicle intermittently.
•Do not disconnect the battery terminals while diagnosing. (Data will be cleared by disconnecting the bat-
tery terminals.)
7. DRIVE CYCLE F
1) Check that the engine coolant temperature at engine start is 30°C (86°F) or less.
2) Start the engine, and warm it up until engine coolant temperature increases over 95°C (203°F).
3) After the engine has reached the state of procedure 2), idle the engine for more than 10 minutes.
NOTE:
Do not disconnect the battery terminals while diagnosing. (Data will be cleared by disconnecting the battery
terminals.)
