12.Drive Cycle
A: PROCEDURE
For the troubleshooting, there are five driving pat-
terns of drive cycles A to E. Driving in the specified
pattern allows to diagnose malfunctioning items
listed below. After the repair of the following trouble
items, be sure to drive the vehicle with the specified
drive patterns to check whether the function is re-
sumed correctly.
1. PREPARATION FOR DRIVE CYCLE
1) Check battery voltage is more than 12 V and fuel
remains half [20 to 40 2 (5.3 to 10.6 US gal, 4.4 to
8.8 Imp gal)].
2) After performing the diagnostics and clearing the
memory, check for any remaining unresolved trou-
ble data. <Ref. to EN(H6DO)(diag)-45, Clear Mem-
ory Mode.>
3) Disconnect the test mode connectors.
NOTE:
•Perform the diagnosis after warming up the en-
gine except when the engine coolant temperature
at starting is specified.
•Perform the diagnosis twice if the DTC marked
with *. After completing the first diagnosis, stop the
engine and perform second diagnosis in same con-
dition.

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. <Ref. to EN(H6DO)(diag)-45, 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. <Ref. to EN(H6DO)(diag)-45, 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.

B: ACTIVATION OF MALFUNCTION
INDICATOR LIGHT
1) When the ignition switch is turned to ON (engine
OFF), the malfunction indicator light (A) in the com-
bination meter illuminates.
NOTE:
If the engine malfunction indicator light does not il-
luminate, perform diagnostics of malfunction indi-
cator light circuit or the combination meter circuit.
<Ref. to EN(H6DO)(diag)-50, MALFUNCTION IN-
DICATOR LIGHT DOES NOT COME ON, Malfunc-
tion Indicator Light.>
2) After starting the engine, the malfunction indica-
tor light goes out. If it does not go off, either the en-
gine or emission control system has malfunction.
3) Turn the ignition switch to OFF and connect the
test mode connector.
(1) When the ignition switch is turned to ON (en-
gine OFF), the malfunction indicator light illumi-
nates.
(2) After the engine starts, malfunction indicator
light blinks in a cycle of 0.5 Hz.(During diagno-
sis)
(3) Malfunction indicator light blinks at a cycle of
3 Hz after diagnosis if there is no trouble. Mal-
function indicator light illuminates if faulty.
