1. INSPECT SHIFT LOCK CONTROL ECU
Using a voltmeter, measure the voltage at each terminal.
HINT:
Do not disconnect the ECU connector.

2. INSPECT SHIFT LOCK SOLENOID
(a) Disconnect the solenoid connector.
(b) Using an ohmmeter, measure the resistance between ter-
minal 1 and 2.
Standard resistance: 21 - 27 W
If the resistance value is not as specified, replace the solenoid.
(c) Apply the battery positive voltage between terminals.
Check that the operation noise can be heard from the so-
lenoid.
If the solenoid does not operate, replace the solenoid.
3. INSPECT SHIFT LOCK CONTROL SWITCH
Inspect that continuity exists between each terminal.

INSPECTION
CAUTION:
Replace the seat belt assembly (outer belt, inner belt, bolts,
nuts or sill-bar) if it has been used in a severe impact. The
entire assembly should be replaced even if damage is not
obvious.
1. Except manual type:
RUNNING TEST (IN SAFE AREA)
(a) Fasten the front seat belts.
(b) Drive the car at 10 mph (16 km/h) and slam on the brakes.
Check that the belt locks and cannot be extended at this
time.
HINT:
Conduct this test in a safe area. If the belt does not lock, remove
the belt mechanism assembly and conduct the following static
check. Also, whenever installing a new belt assembly.
2. Driver 's seat belt (ELR):
STATIC TEST
(a) Make sure that the belt locks when pulled out quickly.
(b) Remove the locking retractor assembly.
HINT:
Before removing the pretensioner connector, be sure to read
the precautionary notice in the RS section.
(c) Tilt the retractor slowly.
(d) Make sure that the belt can be pulled out at a tilt of 15 de-
grees or less, and cannot be pulled out over 45 degrees
of tilt.
If a problem is found, replace the assembly.
3. Except driver's seat belt (ELR/ALR):
STATIC TEST
(a) Make sure that the belt locks when pulled out quickly.
(b) Remove the locking retractor assembly.
HINT:
Before removing the pretensioner connector, be sure to read
the precautionary notice in the RS section.
(c) Pull out the whole belt and measure the length of the
whole belt.
Then retract the belt slightly and pull it out again
(d) Make sure that the belt cannot be extended further.
If a problem is found, replace the assembly.

BRAKE FLUID
BLEEDING
HINT:

If any work is done on the brake system or if air in the
brake lines is suspected, bleed the air from the system.

When bleeding, keep the amount of the fluid within the
line of reservoir between Min. and Max.
NOTICE:

Do not let brake fluid remain on painted surfaces.
Wash it off immediately.

With the reservoir cap removed, when depressing the
brake pedal, the fluid will spray.
1. FILL RESERVOIR WITH BRAKE FLUID
Fluid: SAE J1703 or FMVSS NO. 116 DOT3
2. In case of using TOYOTA hand-held tester:
BLEED HYDRAULIC BRAKE BOOSTER
HINT:
If the hydraulic brake booster has been disassembled, discon-
nect the brake line from the hydraulic brake booster or if the res-
ervoir becomes empty, bleed the hydraulic brake booster.
(a) Turn the ignition switch OFF, depress the brake pedal
more than 40 times.
HINT:
When a pressure in power supply system is released, reaction
force becomes light and stroke becomes longer.
(b) Turn the ignition switch ON, check that the pump stops af-
ter approx. 30 to 40 sec.
NOTICE:
When the pump does not stop, repeat step (a) and (b) again.
(c) With the ignition switch remained ON, depress the brake
pedal more than 20 times.
(d) Observe the procedure in step 4 and bleed the right and
left front brake caliper.
(e) Holding the brake pedal depressed, bleed the right and
left rear brake caliper.
HINT:
It is not necessary to depress the pedal continuously, as brake
fluid flows out by first depressing.
(f) Connect TOYOTA hand-held tester.
(1) Turn the ignition switch OFF, connect the TOYOTA
hand-held tester to DLC3.
(2) Turn the ignition switch ON and select ºAIR BLEED-
INGº on the TOYOTA hand-held tester.
HINT:
Please refer to the TOYOTA hand-held tester operator's manu-
al for further details.

(g) Bleed right front brake line.
(1) Select ºFR LINEº on the TOYOTA hand-held tester.
(2) With ºFR LINEº turned ON with the TOYOTA hand-
held tester, depress the brake pedal and hold it to
bleed the right front brake caliper.
(3) Repeat step (2) until there are no more air bubbles
in the fluid.
(h) Bleed left front brake line.
(1) Select ºFL LINEº on the TOYOTA hand-held tester.
(2) With ºFL LINEº turned ON with the TOYOTA hand-
held tester, depress the brake pedal and hold it to
bleed the left front brake caliper.
(3) Repeat step (2) until there are no more air bubbles
in the fluid.
(i) w/ ABS & TRAC & VSC only:
Bleed rear brake line.
(1) Select ºRR LINEº on the TOYOTA hand-held tester.
(2) With ºRR LINEº turned ON with the TOYOTA hand-
held tester, bleed the left and right rear brake cali-
per.
(j) Disconnect the TOYOTA hand-held tester from DLC3.
(k) Clear the DTC (See page DI-505).
3. In case of using ABS actuator checker (SST):
BLEED HYDRAULIC BRAKE BOOSTER
HINT:
If the hydraulic brake booster has been disassembled, discon-
nect the brake line from the hydraulic brake booster or if the res-
ervoir becomes empty, bleed the hydraulic brake booster.
(a) Disconnect the 2 connectors from the hydraulic brake
booster.
