2 CHECK OPERATION OF OCV
(a) Start the engine.
(b) Check the engine speed with conditions (1) and then (2).
(1) Disconnect the camshaft timing oil control valve
connector.
(2) Apply battery positive voltage between the termi-
nals of the camshaft timing oil control valve.

3 READ OUTPUT DTC(CHECK IF DTC OUTPUT RECURS)
(a) Clear the DTC.
(1) Disconnecting the battery terminal or removing the EFI and ECTS fuses for more than 60 sec.
(b) Start and warm up the engine.
(c) Drive the vehicle around for 10 minutes or more.
(d) Read output DTC.
Standard: No DTC output.
HINT:
*: DTCs P0011/59 or P0012/59 is output when a foreign object in engine oil is caught in some part of the
system. These codes will stay registered even if the system returns to normal after a short time. These for-
eign objects are then captured by the oil filter, thus eliminating the source of the problem.

(b)If you have no hand±held tester, perform the following
steps (1) to (6).
(1)Turn the ignition switch ON.
(2)Using SST, connect between terminals 13 (TC) and4 (CG) of the DLC3.
SST09843±18040
(3)Read DTC by observing the CHK ENG lamp. If any DTC is not detected, the CHK ENG lamp blinks as
shown in the illustration.
(4)Example If DTC 12 and DTC 31 are detected, the CHK ENG
flashes 1 time (for 0.5 sec) and flashes 2 times after
the 1.5 sec interval, then flashes 3 times after a 2.5
sec interval from the previous DTC and flashes 1
time.
If the interval between the previous DTC and the
next DTC is 4.5 sec, it means the previous DTC is
the last one of the multiple string DTCs. The CHK
ENG lamp repeats the indication of DTCs from the
initial cycle. (Refer to the illustration on the left)
(5)Check the details of the malfunction using the DTC chart on page 05±16.
(6) After completing the check, disconnect terminals 13
(TC) and 4 (CG) and turn off the display.
HINT:
In the event that 2 or more DTCs are detected, the CHK ENG
lamp will indicate the smaller number DTC first.
(c) Clearing the DTCs using the hand±held tester: (1) Connect the hand±held tester to the DLC3.
(2) Turn the ignition switch ON.
(3) When operating hand±held tester to erase thecodes, the DTCs and freeze frame data will be
erased. (See the hand±held tester's instruction
book for operating instructions.)
(d) Clearing the DTCs not using the hand±held tester: (1) Disconnect the battery terminal or remove the EFI
fuse for more than 60 seconds.

5.CHECK FOR INTERMITTENT PROBLEMS
Hand±held tester only:
By putting the vehicle's engine ECM in check (test) mode, 1 trip detection logic is possible instead of 2 trip
detection logic, and sensitivity to detect faults is increased. This makes it eas\
ier to detect intermittent prob-
lems.
(a)Clear the DTC. (See step 3.)
(b)Set the check (test) mode. (See step 3.)
(c)Perform a simulation test. (See page 01±22)
(d)Check the connector and terminal. (See page 01±32)
(e)Wiggle the harness and the connector. (See page 01±32)
