(b) Clear DTCs.
(1) Using SST, connect terminals Tc and CG of the
DLC3.
SST 09843-18040
(2) Turn the ignition switch to the ON position.
(3) Clear the DTCs stored in the ECU by depressing the
brake pedal 8 or more times within 5 sec.
(4) Check that the ABS warning light and VSC warning
light shows normal blinking patterns.
(5) Remove the SST from the DLC3.
SST 09843-18040
HINT:
Cancellation cannot be preformed by removing the battery
cable or the ECU-IG fuse.
3. DTC CHECK/CLEAR (USING HAND-HELD TESTER)
(a) Check DTCs.
(1) Connect the hand-held tester to the DLC3.
(2) Turn the ignition switch to the ON position.
(3) Read the DTCs following the prompts on the tester
screen.
HINT:
Refer to the hand-held tester operator's manual for further de-
tails.
(b) Clear the DTCs.
(1) Connect the hand-held tester to the DLC3.
(2) Turn the ignition switch to the ON position.
(3) Operate the hand-held tester to erase the codes.
HINT:
Refer to the hand-held tester operator's manual for further de-
tails.
4. DATA LIST
HINT:
According to the DATA LIST displayed on the Hand-held tester, you can read the value and status of the
switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as a first step of trouble-
shooting is one of the methods to shorten the labor time.
(a) Connect the Hand-held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) From the display on the tester, read the ºDATA LISTº.

5. ACTIVE TEST
HINT:
Performing the ACTIVE TEST using the hand-held tester allows the relay and actuator, etc. to operate with-
out removing any parts. Performing the ACTIVE TEST as the first step of troubleshooting is one of the meth-
ods to shorten labor time.
It is possible to display the DATA LIST during the ACTIVE TEST.
(a) Connect the hand-held tester to the DLC3.
(b) Turn the ignition switch to the ON position.
(c) According to the display on the tester, perform the ºACTIVE TESTº.
HINT:
Ignition switch must be turned to the ON position to proceed to the ACTIVE TEST using the hand-held tester.

6. ACTUATOR CHECK
(a) Turn the ignition switch to the ON position while pressing
the A/C control AUTO switch and R/F (Recirculation /
Fresh) switch simultaneously.
(b) As each damper, motor and relay automatically operate
the actuator check at 1 second intervals from step No.1
to No.10 continuously, check the temperature and air flow
visually and by hand.
If a slower display is desired, press the temperature up switch
and change the display in the step operation. Each time the
temperature up switch is pressed, the display changes by 1
step.
HINT:

Codes are displayed from the smaller to the larger num-
bers in order.

To cancel the check mode, press the ºOFFº switch.
