3. INSPECT IDLE AIR CONTROL VALVE
NOTICE:

It is impossible to check the resister value and the op-
eration of ISCV by itself, because the ISCV has an IC
circuit inside it, which transforms the duty signal
from the ECM to the derive signal.

After checking, erase the DTC.

Clear the DTC after inspection.
HINT:
When the ISCV system has malfunctions except for its adher-
ence, DTC P0511 is detected.
(a) Operation inspection.
(1) Connect the ISC valve connector to the ISC valve.
(2) Check the ISC valve movement when the ignition
switch is turned ON.
Movement:
Half open fully close  fully open half open
HINT:
ISC valve moves within 0.5 second.

INSPECTION
1.INSPECT COOLANT (See page 16±13)
2.INSPECT ENGINE OIL (See page 17±6)
3. INSPECT BATTERY
Standard specific gravity: 1.25 to 1.29 at 20 C (68 F)
4. INSPECT AIR CLEANER FILTER ELEMENT SUB±ASSY
5.INSPECT SPARK PLUG (See page 18±9)
6. INSPECT V±RIBBED BELT
7. INSPECT IGNITION TIMING
(a) Warm up engine.
(b) When using hand±held tester:(1) Connect the hand±held tester to the DLC3.
(2) Enter DATA LIST MODE on the hand±held tester.
Ignition timing: 8 to 12  BTDC
HINT:
Please refer to the hand±held tester operator's manual if you
need help to select DATA LIST.
(c) When not using hand±held tester:
(1) Using SST, connect terminals 13 (TC) and 4 (CG)of DLC3.
SST 09843±18040
NOTICE:

Make sure of the terminal numbers before connecting
them. Connection with a wrong terminal can damage
the engine.

Turn OFF all electrical systems before connecting the
terminals.

Operate the inspection after the cooling fan motor is
turned OFF.
(2) Remove the cylinder head cover No.2.
(3) Pull out the wire harness as shown in the illustration.
Connect the clip of the timing light to the engine.
NOTICE:

Use a timing light which detects the first signal.

After checking, be sure to wrap the wire harness with
tape.
(4) Inspect ignition timing at idle.
Ignition timing: 8 to 12  BTDC
NOTICE:
When checking the ignition timing, shift the transmission
to the neutral position.
HINT:
Run the engine at 1,000 to 1,300 rpm for 5 seconds, check that
the engine rpm returns to the idle speed.
