5. DRIVE CYCLE D
• DRIFT DIAGNOSIS
1) Make sure that the engine coolant temperature at engine starting is less than 30°C (86°F).
2) Make sure that fuel remains 9.6 2 or more (2.5 US gal, 2.1 Imp gal) and the battery voltage is 10.9 V or
more.
3) Make sure that the engine coolant temperature rises for more than 10°C (50°F) from the level of engine
starting and is also above 75°C (167°F).
4) Idle the engine for more than 120 seconds in the condition of step 3.
• STUCK DIAGNOSIS
1) Make sure that the battery voltage is more than 10.9 V.
2) Perform the Clear Memory Mode. <Ref. to EN(H4SO)(diag)-43, Clear Memory Mode.>
3) Drive the vehicle for the distance equal to the fuel of 50 2 (13.2 US gal, 11 Imp gal).
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.)
