(2) Connect the OBD II scan tool or TOYOTA hand±
held tester to DLC3 under the instrument panel low-
er pad.
(3) Turn the ignition switch ON and turn the OBD II scan
tool or TOYOTA hand±held tester switch ON.
(4) Use the OBD II scan tool or TOYOTA hand±held
tester to check the DTCs and freezed frame data
and note them down. (For operating instructions,
see the OBD II scan tool's instruction book.)
(5) See page DI±3 to confirm the details of the DTCs.
NOTICE:

When simulating symptoms with an OBD II scan tool
(excluding TOYOTA hand±held tester) to check the
DTCs, use normal mode. For code on the DTC chart
subject to º2 trip detection logicº, perform the follow-
ing either action.

Turn the ignition switch OFF after the symptom is
simulated the first time. Then repeat the simulation
process again. When the problem has been simulated
twice, the MIL lights up and the DTCs are recorded in
the ECM.

Check the 1st trip DTC using Mode 7 (Continuous Test
Results) for SAE J1979.
(c) Clear the DTC.
The DTCs and freezed frame data will be erased by either
action.
(1) Operating the OBD II scan tool (complying with SAE
J1978) or TOYOTA hand±held tester to erase the
codes. (See the OBD II scan tool's instruction book
for operating instructions.)
(2) Disconnecting the battery terminals or EFI fuse.
NOTICE:
If the TOYOTA hand±held tester switches the ECM from
normal mode to check mode or vice±versa, or if the ignition
switch is turned from ON to ACC or OFF during check
mode, the DTCs and freezed frame data will be erased.

ment panel.
(3) Turn the ignition switch ON and push the OBD II
scan tool or TOYOTA hand±held tester switch ON.
(4) Use the OBD II scan tool or TOYOTA hand±held
tester to check the DTC and freezed frame data and
note them down (For operating instructions, see the
OBD II scan tool's instruction book.).
(5) See page DI±197 to confirm the details of the DTC.
NOTICE:

When simulating symptoms with an OBD II scan tool

lowing either action.

ter to erase the codes. (See the OBD II scan
tool's instruction book for operating instruc-
tions.)

Disconnecting the battery terminals or EFI
fuse.
NOTICE:
If the TOYOTA hand±held tester switches the ECM from
normal mode to check mode or vice±versa, or if the ignition
switch is turned from ON to ACC or OFF during check
mode, the DTCs and freezed frame data will be erased.
3. INSPECT DIAGNOSIS (Check Mode)
HINT:
TOYOTA hand±held tester only:
Compared to the normal mode, the check mode has an in-
creased sensitivity to detect malfunctions.
Furthermore, the same diagnostic items which are detected in
the normal mode can also be detected in the check mode.

ABS Warning Light Circuit
CIRCUIT DESCRIPTION
If the ECU detects any trouble, it lights the ABS warning light while at the same time prohibiting ABS control.
At this time, the ECU records a DTC in memory.
Connect terminals Tc and E
1 of the DLC1 or DLC2 to make the ABS warning light blink and output the DTC.
WIRING DIAGRAM
INSPECTION PROCEDURE
Troubleshoot in accordance with the chart below for each trouble symptom
ABS warning light does not light upGo to step 1
ABS warning light remains onGo to step 2
1 Check ABS warning light.
See combination meter troubleshooting on page BE±2.
NG Repair bulb or combination meter assembly.
OK
Check for open circuit in harness and connector between GAUGE fuse, DLC2 and ABS ECU
(See page IN±31).

The ºCurrent Flow Chartº section, describes which parts each power source (fuses, fusible links, and circuit breakers)
transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system
are explained. Since all System Circuit diagrams start from the power source, the power source system must be fully
understood.
