HINT:
The seat belt pretensioner operates simultaneously as the LED
of the SST activation switch lights up.
(e) Dispose of the front seat outer belt (with seat belt preten-
sioner).
CAUTION:
The front seat outer belt is very hot when the seat belt
pretensioner is activated, so leave it alone for at least
30 minutes after activation.
Use gloves and safety glasses when handling a front
seat outer belt with the activated seat belt pretension-
er.
Always wash your hands with water after completing
the operation.
Do not apply water, etc. to a front seat outer belt with
the activated seat belt pretensioner.
(1) Remove the disc wheel and SST.
(2) Place the front seat outer belt in a vinyl bag, tie the
end tightly and dispose of it in the same way as oth-
er general parts.

ON-VEHICLE INSPECTION
1. CHECK PEDAL HEIGHT
Pedal height from asphalt sheet:
153.3 - 163.3 mm (6.035 - 6.429 in.)
If the pedal height is incorrect, adjust it.
2. IF NECESSARY, ADJUST PEDAL HEIGHT
(a) Remove the lower No. 1 instrument panel and lower LH
instrument panel insert (See page BO-87).
(b) Disconnect the connector from the stop light switch.
(c) Loosen the stop light switch lock nut and remove the stop
light switch.
(d) Loosen the push rod lock nut.
(e) Adjust the pedal height by turning the pedal push rod.
(f) Tighten the push rod lock nut.
Torque: 25 N´m (260 kgf´cm, 19 ft´lbf)
(g) Install the stop light switch.
(h) Connect the connector to the stop light switch.
(i) Push the brake pedal in 5 - 15 mm (0.20 - 0.59 in.), turn
the stop light switch to lock the nut in the position where
the stop light goes off.
(j) After installation, push the brake pedal in 5 - 15 mm (0.20
- 0.59 in.), check that stop light lights up.
(k) After adjusting the pedal height, check the pedal freeplay.
(l) Install the lower LH instrument panel insert and lower No.
1 instrument panel (See page BO-87).
3. CHECK PEDAL FREEPLAY
(a) Stop the engine and depress the brake pedal several
times until there is no more vacuum left in the booster.
(b) Push in the pedal by hand until the beginning of the resis-
tance is felt, then measure the distance.
Pedal freeplay: 1 - 6 mm (0.04 - 0.24 in.)
If incorrect, check the stop light switch clearance. If the clear-
ance is OK, then troubleshoot the brake system.
Stop light switch clearance:
0.5 - 2.4 mm (0.020 - 0.094 in.)
HINT:
The freeplay to the 1st resistance is due to the play between the
clevis and pin. This is magnified up to 1 - 6 mm (0.04 - 0.24 in.)
at the pedal.

If the voltmeter reading is more than standard voltage, replace
the voltage regulator.
If the voltmeter reading is less than standard voltage, check the
voltage regulator and generator as follows:
With terminal F grounded, start the engine and
check the voltmeter reading of terminal B.
If the voltmeter reading is more than standard volt-
age, replace the voltage regulator.
If the voltmeter reading is less than standard volt-
age, check the generator.
9. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn on the high
beam headlights and place the heater blower switch at
ºHIº.
(b) Check the reading on the ammeter.
Standard amperage: 30 A or more
If the ammeter reading is less than the standard amperage, re-
pair the generator.
HINT:
If the battery is fully charged, the indication will sometimes be
less than standard amperage.

ABS Warning Light Circuit
CIRCUIT DESCRIPTION
If the ECU detects trouble, the ABS warning light lights up and ABS control is prohibited at the same time.
At this time, the ECU records a DTC in memory.
Connecting terminals Tc and E
1 of the DLC1 makes the ABS warning light blink and output the DTC.

CIRCUIT DESCRIPTION
The BRAKE warning light lights up when the brake fluid is insufficient, when the parking brake is ap-
plied or when the EBD is defective.
If the translate ECU detects trouble, it makes VSC warning light lights up while prohibiting VSC & TRAC
control. At this time, the ECU records a DTC in memory. Connect terminals Tc and E
1 of the DLC1 or
DLC2 to make BRAKE warning light blink and output the DTC.
