(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.
