Drive Cycle
ENGINE (DIAGNOSTICS)
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. <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.
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.)

Clear Memory Mode
ENGINE (DIAGNOSTICS)
13.Clear Memory Mode
A: OPERATION
1. SUBARU SELECT MONITOR (NORMAL
MODE)
1) On the «Main Menu» display screen, select the
{Each System Check} and press the [YES] key.
2) On the «System Selection Menu» display
screen, select the {Engine} and press the [YES]
key.
3) Press the [YES] key after the information of en-
gine type has been displayed.
4) On the «Engine Diagnosis» display screen, se-
lect the {Memory Clear} and press the [YES] key.
5) When the “Done” and “Turn Ignition Switch OFF”
are shown on the display screen, turn the ignition
switch to OFF and then Subaru Select Monitor
switch to OFF.
NOTE:
•Initial diagnosis of electronic throttle control is
performed after memory clearance. For this rea-
son, start the engine after 10 seconds or more have
elapsed since the ignition switch was turned to ON.
•For detailed operation procedure, refer to the
“SUBARU SELECT MONITOR OPERATION
MANUAL”.
2. SUBARU SELECT MONITOR (OBD
MODE)

2) On the «System Selection Menu» display
screen, select the {Engine} and press the [YES]
key.
3) Press the [YES] key after the information of en-
gine type has been displayed.
4) On the «Engine Diagnosis» display screen, se-
lect the {OBD System} and press the [YES] key.
5) On the «OBD Menu» display screen, select
{DTC Clear} and press the [YES] key.
6) When the “Perform Diagnostic Code(s) Clear?”
is shown on the screen, press the [YES] key.
7) Turn the ignition switch to OFF and then turn the
Subaru Select Monitor switch to OFF.
NOTE:
•Initial diagnosis of electronic throttle control is
performed after memory clearance. For this rea-
son, start the engine after 10 seconds or more have
elapsed since the ignition switch was turned to ON.
•For detailed operation procedure, refer to the
“SUBARU SELECT MONITOR OPERATION
MANUAL”.
3. GENERAL SCAN TOOL
