If incorrect, check the stop light switch clearance. If the clear-
ance is OK, then troubleshoot the brake system.
Stop light switch clearance: 1.9 mm (0.075 in.)
HINT:
The freeplay to the 1st point of resistance is due to the play be-
tween the clevis, pedal link and pin. It is 1.0 - 6.0 mm (0.039 -
0.236 in.) on the pedal.
4. CHECK PEDAL RESERVE DISTANCE
(a) Remove the floor carpet.
(b) Release the parking brake.
With the engine running, depress the pedal and measure
the pedal reserve distance, as shown.
Pedal reserve distance at 490 N (50 kgf, 110.1 lbf):
More than 116 mm (4.57 in.)
If the reserve distance is incorrect, troubleshoot the brake sys-
tem.

(5) When the solenoids are OFF, check that the brake
pedal can be depressed.
If the pedal cannot be depressed, replace the hydraulic brake
booster.
(6) Once, release the brake pedal. After depressing
and holding the brake pedal with stable force, turn
the SFLH and SFLR solenoids ON simultaneously.
HINT:
To protect the solenoids, TOYOTA hand-held tester turns OFF
automatically for 2 sec. after every solenoid has been turned
ON.
(7) Once release the brake pedal when the solenoids
are OFF, check that the brake pedal can be de-
pressed.
If the pedal cannot be depressed, replace the hydraulic brake
booster.
(g) Jack up and support the vehicle.
(h) Release the parking brake lever.
(i) Inspect the rear ABS solenoid.
(1) Select the ºSRHº on the TOYOTA hand-held tester.
(2) Turn the ºSRHº ON with the TOYOTA hand-held
tester and depress the brake pedal with stable
force, and rotate the right rear wheel by hand and
check it.
HINT:

To protect the solenoids, TOYOTA hand-held tester turns
OFF automatically for 2 sec. after every solenoid has
been turned ON.

When rotating the wheel fast, the fail-safe function is acti-
vated and judgement cannot be made properly. So rotate
the wheel as slowly as possible.

When solenoid is OFF, the wheel might stop temporarily.
However if the wheel rotates again, the function works
normally.
If the rear wheels stop, replace the hydraulic brake booster.
(3) Once, release the brake pedal and turn the ºSRHº
OFF, after depressing the brake pedal with stable
force and stop the rear right wheel by hand and
check it.
If the rear wheel rotate, replace the hydraulic brake booster.
(4) Depress the pedal with stable force, then turn the
ºSRHº and ºSRRº ON simultaneously.
(5) When the solenoids are ON, rotate the rear wheel
by hand and check it.
HINT:

To protect the solenoids, TOYOTA hand-held tester turns
OFF automatically for 2 sec. after every solenoid has
been turned ON.

(k) Inspect the rear TRAC & VSC solenoid operation.
(1) Select the ºSA3º and ºSTRº on the TOYOTA hand-
held tester.
(2) Turn the ºSA3º and ºSTRº ON simultaneously with
the TOYOTA hand-held tester, and check that the
rear wheel does not rotate by hand.

NOTICE:
When operating it continuously, set the interval of more
than 20 sec.
If the rear wheels stop, replace the hydraulic brake booster.
(l) Inspect the right rear ABS solenoid.
(1) Select the ºSA3º, ºSTRº and ºSRRHº, on the TOYO-
TA hand-held tester.
(2) Turn the ºSA3º, ºSTRº and ºSRRHº ON simulta-
neously with the TOYOTA hand-held tester, and
check that the right rear wheel by rotating it by hand.
