BRAKE
INSPECTION
1. INSPECT BRAKE LINE PIPES AND HOSES
HINT:
Check in a well lighted area. Check the entire circumference
and length of the brake hoses using a mirror as required. Turn
the front wheels fully right or left before checking the front brake.
(a) Check all brake lines and hoses.

Check for damage.

Check for wear.

Check for deformation.

Check for cracks.

Check for corrosion.

Check for leaks.

Check for bends.

Check for twists.
(b) Check all clamps for tightness and connections for leak-
age.
(c) Check that the hoses and lines are clear of sharp edges,
moving parts and the exhaust system.
(d) Check that the lines installed in grommets pass through
the center of the grommets.
2. INSPECT FRONT BRAKE PADS AND DISCS (See page
BR-26)
HINT:
If a squealing or scraping noise comes from the brake during
driving, check the pad wear indicator to see if it is contacting the
disc. If so, the disc pad should be replaced.
3. INSPECT REAR BRAKE LININGS AND DRUMS (See
page BR-32)

PRE-CHECK
1. DIAGNOSIS SYSTEM
(a) Check the indicator.
When the ignition switch is turned ON, check that the ABS
warning light goes on for 3 seconds.
HINT:
If the indicator check result is not normal, proceed to trouble-
shooting for the ABS warning light circuit (See page DI-138).
(b) Check the DTC.
(1) Turn the ignition switch ON.
(2) Disconnect the short pin from the DLC1.
(3) Using SST, connect terminals Tc and E
1 of the
DLC1.
SST 09843-18020
(4) Read the DTC from the ABS warning light on the
combination meter.
HINT:

If no code appears, inspect the diagnostic circuit or ABS
warning light circuit (See page DI-141 or DI-138).

As an example, the blinking patterns for normal code and
codes 11 and 21 are shown in the illustration.
(5) Code are explained in the code table on page
DI-1 15.
(6) After completing the check, disconnect terminals Tc
and E
1, and turn off the display.
If 2 or more malfunctions are indicated at the same time, the
lowest numbered DTC will be displayed 1st.

(c) Clear the DTC.
(1) Using SST, connect terminals Tc and E
1 of the
DLC1 and remove the short pin from the DLC1.
SST 09843-18020
(2) IG switch ON.
(3) Clear the DTC stored in ECU by depressing the
brake pedal 8 or more times within 3 seconds.
(4) Check that the warning light shows the normal
code.
(5) Remove the SST from the terminals of the DLC1.
SST 09843-18020
(6) Connect the short pin to the DLC1.
HINT:
Cancellation can also be done by removing the DOME fuse , but
in this case, other memory systems will also be cancelled out.
(d) Using TOYOTA break-out-box and TOYOTA hand-held
tester, measure the ECU terminal values.
(1) Hook up the TOYOTA hand-held tester and TOYO-
TA break-out-box to the vehicle.
(2) Read the ECU input/output values by following the
prompts on the tester screen.
HINT:
TOYOTA hand-held tester has a ºSnapshot º function. This re-
cords the measured values and is effective in the diagnosis of
intermittent problems.
Please refer to the TOYOTA hand-held tester/TOYOTA break
out-box operators manual for further details.

2. SPEED SENSOR SIGNAL CHECK
(a) Check the speed sensor signal.
(1) Turn the ignition switch OFF.
(2) Using SST, connect terminals Ts and E
1 of the
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-138).
(5) Drive the vehicle faster than 45 km/h (28 mph) for
several seconds.
(6) Stop the vehicle.
(7) Using SST, connect terminals Tc and E
1 of the
DLC1.
SST 09843-18020
(8) Read the number of blinks of the ABS warning light.
HINT:
See the list of DTCs 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 malfunctions are indicated at the same time,
the lowest numbered code will be displayed 1st.
(9) After doing the check, disconnect terminals Ts and
E
1, and Tc and E1 of the DLC1, and turn ignition
switch OFF.
