PRE-CHECK
1. DIAGNOSIS SYSTEM
(a) Check the warning lights.
(1) Release the parking brake pedal.
(2) When the ignition switch is turned ON, check that
the ABS warning light, VSC warning light, VSC OFF
indicator light, BRAKE warning light and SLIP indi-
cator light goes on for approx. 3 seconds.
HINT:
When the parking brake is applied or the level of the brake
fluid is low, the BRAKE warning light is lit.
If the indicator check result is not normal, proceed to trou-
bleshooting for the ABS warning light circuit, VSC warn-
ing light circuit, VSC OFF indicator light circuit, BRAKE
warning light circuit or SLIP indicator light circuit.

BRAKE warning light circuitDI-330
SLIP indicator light circuitDI-333
(b) In case of not using TOYOTA hand-held tester:
Check the DTC of ABS & BA & TRAC & VSC ECU.
(1) Using SST, connect terminals Tc and E
1 of DLC1.
SST 09843-18020
(2) Turn the ignition switch ON.
(3) Read the DTC from the ABS warning light and VSC
warning light on the combination meter.
HINT:
If no code appears, inspect the diagnostic circuit, ABS
warning light circuit or VSC waning light circuit.

If 2 or more malfunction codes are identified at the same time,
the lowest numbered DTC will be displayed 1st.
(c) In case of not using TOYOTA hand-held tester:
Check the DTC of translate ECU.
(1) Release the parking brake pedal.
(2) Check the brake fluid level.
(3) Using SST, connect terminals Tc and E
1 of DLC1.
SST 09843-18020
(4) Turn the ignition switch ON.
(5) Read the DTC from the BRAKE warning light.
HINT:
If no code appears, inspect the diagnostic circuit, and
BRAKE warning light circuit.
Trouble AreaSee page
Tc terminal circuitDI-342
BRAKE warning light circuitDI-330
When the parking brake is applied or the level of the brake
fluid is low, the BRAKE warning light is lit.
If every sensor is normal, a normal code is output. (A cycle
of 0.25 sec. ON and 0.25 sec. OFF is repeated.)
If 2 or more malfunction codes are identified at the same
time, the lowest numbered code will be displayed 1st.

(2) Using SST, connect terminals Ts and E
1 of DLC1.
SST 09843-18020
(3) Start the engine.
(4) Check that the ABS warning light blinks.
HINT:
If the ABS warning light does not blink, inspect the ABS warning
light circuit (See page DI-325).
(5) Drive vehicle straight forward.
Drive vehicle at a speed faster than 45 km/h (28
mph) for several seconds.
HINT:
The sensor check may not be completed if the front wheels are
spun or the steering wheel is steered during this check.
(6) Stop the vehicle.
(7) Using SST, connect terminals Tc and E
1 of DLC1.

(8) Read the number of blinks of the ABS warning light.
HINT:
See the list of DTC shown on the next page.
If every sensor is normal, a normal code is output (A cycle
of 0.25 sec. ON and 0.25 sec. OFF is repeated).
If 2 or more malfunction codes are identified at the same
time, the lowest numbered code will be displayed 1st.
(9) After doing the check, disconnect the SST from ter-
minals Ts and E
1, Tc and E1 of DLC1, and turn the
