(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)

CHECK ENGINE WARNING LIGHT CIRCUIT
CIRCUIT DESCRIPTION
The CHK ENG is used to indicate the ECM’s detection of a vehicle malfunction.
The instrument panel IGN fuse provides the circuit power and the ECM provides the circuit ground that illumi-
nates the CHK ENG.
CHK ENG operations should be checked visually:
The CHK ENG should be illuminated when the ignition is first turned to ON. If the CHK ENG is always ON
or OFF, use the hand−held tester and follow the procedures below to determine the cause of the problem.

INSPECTION PROCEDURE
HINT:
S After completing repairs, confirm that P0380 is not present again.
S Read freeze frame data using the hand −held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the
vehicle was running or stopped, if the engine was warmed up or not, if the air −fuel ratio was lean or
rich, and other data from the time the malfunction occurred.
1 CHECK OTHER DTC OUTPUT(IN ADDITION TO DTC P0380)
(a) Connect the hand −held tester to the DLC3.
(b) Turn the ignition switch to ON and turn the hand −held tester ON.
(c) Select the item ”DIAGNOSIS / OBD/MOBD / DTC INFO / CURRENT CODES”.
(d) Read DTCs.
Result:
Display (DTC output)Proceed to
P0380A
P0380 and P0622B
HINT:
If any other codes besides P0380 and P0622 are output, perform troubleshooting for those DTCs first.
