DTC CHECK / CLEAR
USING SST (CHECK WIRE):
1.
CHECK DTC
(a)
Using SST, connect terminals Tc and CG of the DLC3.
SST
09843–18040
(b)
Turn the ignition switch to the ON position.
(c)
Read the DTC from the ABS and VSC TRAC warning
lights on the combination meter.
HINT:
If no code appears, inspect the diagnostic circuit, ABS
warning light circuit or VSC TRAC warning light circuit.
Trouble Area
See page
Tc terminal circuit
ABS warning light circuit
VSC TRAC warning light circuit
As examples, the blinking patterns for normal system
code and codes 11 and 21 are shown on the left.
(1)
Codes are explained in the code table on page
(2)
After completing the check, disconnect terminals Tc
and CG of the DLC3, and turn off the display.
If 2 or more trouble codes are identified at the same time, the
DTCs will be displayed in ascending order.
2.
CHECK TRANSLATE DTC
HINT:
Once the ignition switch is turned off, all DTCs in the translate
ECU are cleared.
(a)
Release the parking brake pedal.
(b)
Check the brake fluid level.
(c)
Using SST, connect terminals Tc and CG of the DLC3.
SST
09843–18040
(d)
Read the DTC of the BRAKE warning light.
NOTICE:
When reading DTCs, be sure to be seated in the driver’s
seat and depressing the brake pedal.

HINT:
If no code appears, inspect the diagnostic circuit, and
BRAKE warning light circuit.
Trouble Area
See page
Tc terminal circuit
BRAKE warning light circuit
When the parking brake is applied or the level of the brake
fluid is low, the BRAKE warning light comes on.
If all sensors are normal, a normal system code is output.
(A cycle of 0.25 sec. ON and 0.25 sec. OFF is repeated.)
If 2 or more trouble codes are identified at the same time,
the codes will be displayed in ascending order.
USING HAND–HELD TESTER:
3.
CHECK DTC
(a)
Connect the hand–held tester to the DLC3.
(b)
Turn the ignition switch to the ON position.
(c)
Read the DTC by following the prompts on the tester
screen.
HINT:
Refer to the hand–held tester operator’s manual for further de-
tails.

(b)
Turn the ignition switch to the ON position.
(c)
Clear the DTC stored in the ECU by depressing the brake
pedal 8 times or more within 5 seconds.
(d)
Check that the warning light indicates the normal code.
(e)
Remove the SST from the terminals of the DLC3.

HINT:
Cancellation cannot be done by removing the battery cable or
ECU–IG fuse.
USING HAND–HELD TESTER:
5.
CLEAR DTC
(a)
Hook up the hand–held tester to the DLC3.
(b)
Turn the ignition switch to the ON position.
(c)
Operate the hand–held tester to erase the codes.
HINT:
(d)

FREEZE FRAME DATA
1.
FREEZE FRAME DATA
HINT:
Whenever a DTC is detected or the ABS operates, the skid control ECU stores the current vehicle (sen-
sor) state as freeze frame data.
The skid control ECU stores the number of times (maximum: 31) the ignition switch has been turned
from off to the ON position since the last time the ABS was activated. However, if the vehicle was
stopped or at low speed (4.3 mph (7 km/h) or less), or if a DTC is detected, the skid control ECU will
not count the number since then.
Freeze frame data at the time the ABS operates:
The skid control ECU stores and updates data whenever the ABS system operates.
When the ECU stores data at the time a DTC is detected, the data stored when the ABS operated is
erased.
Freeze frame data at the time a DTC is detected:
When the skid control ECU stores data at the time a DTC is detected, no updates will be performed
until the data is cleared.
(a)
Connect the hand–held tester to the DLC3.
(b)
Turn the ignition switch to the ON position.
(c)
From the display on the tester, select the ”FREEZE FRAME DATA”.
