Idle Speed
MECHANICAL
3. Idle Speed
A: INSPECTION
1) Before checking the idle speed, check the fol-
lowing item:
(1) Check the air cleaner element is free from
clogging, ignition timing is correct, spark plugs
are in good condition, and hoses are connected
properly.
(2) Check the malfunction indicator light does
not illuminate.
2) Idle the engine.
3) Stop the engine, and turn the ignition switch to
OFF.
4) Insert the cartridge to Subaru Select Monitor.
5) Connect the Subaru Select Monitor to data link
connector.
6) Turn the ignition switch to ON and Subaru Select
Monitor switch to ON.
7) Select {Each System Check} in Main Menu.
8) Select {Engine} in Selection Menu.
9) Select {Current Data Display & Save} in Engine
Control System Diagnosis.
10) Select {Data Display} in Data Display Menu.
11) Start the engine, and read the engine idle
speed.
12) Check the idle speed when no-loaded. (Head-
light, heater fan, rear defroster, radiator fan, A/C
and etc. are OFF)
Idle speed [No load and gears in neutral]:
650±50 rpm
13) Check the idle speed when loaded. (Turn the A/
C switch to “ON” and operate the compressor for at
least one minute before measurement.)
Idle speed [A/C ON and gears in neutral]:
770±50 rpm
NOTE:
Idle speed cannot be adjusted manually, because
the idle speed is automatically adjusted. If the pre-
scribed idle speed cannot be maintained, refer to
General On-board Diagnosis Table under “Engine
Control System”. sic Diagnostic Procedure.>
