ON−VEHICLE INSPECTION
1. CHECK PEDAL HEIGHT
Pedal height from dash panel:
167.5 − 177.5 mm (6.594 − 6.988 in.)
2. IF NECESSARY, ADJUST PEDAL HEIGHT
(a) Disconnect the connector from the stop light switch.
(b) Loosen the stop light switch lock nut and remove the stop
light switch.
(c) Loosen the push rod lock nut.
(d) Adjust the pedal height by turning the pedal push rod.
(e) Tighten the push rod lock nut. Torque: 25 N·m (260 kgf·cm, 19 ft·lbf)
(f) Install the stop light switch and turn it until it lightly con-
tacts the pedal stopper.
(g) Turn the stop light switch back one turn.
(h) Check the clearance (A) between the stop light switch and pedal.
Clearance: 0.5 − 2.4 mm (0.020 − 0.094 in.)
(i) Tighten the stop light switch lock nut.
(j) Connect the connector to the stop light switch.
(k) Check that the stop lights come on when the brake pedal
is depressed, and go off when the brake pedal is re-
leased.
(l) earance (A) between the stop light switch and the pedal
stopper has been adjusted correctly, the pedal freeplay
will meet the specifications.
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.

Pedal freeplay: 3 − 6 mm (0.12 − 0.24 in.)
HINT:
The freeplay to the 1st resistance is due to the play between the
clevis and pin. This is magnified up to 3 − 6 mm (0.12 − 0.24 in.)
at the pedal.

CHARGING CHARGING SYSTEM
1996 LAND CRUISER (RM451U)
If the light does not operate as specified, troubleshoot the dis-
charge warning light circuit.
6. INSPECT CHARGING CIRCUIT WITHOUT LOAD
HINT:
If a battery/generator tester is available, connect the tester to
the charging circuit as per the manufacturer’s instructions.
(a) If a tester is not available, connect a voltmeter and amme-
ter to the charging circuit as follows:
Disconnect the wire from terminal B of the generator
and connect it to the negative ( −) lead of the amme-
ter.
Connect the positive (+) lead of the ammeter to ter-
minal B of the generator.
Connect the positive (+) lead of the voltmeter to ter-
minal B of the generator.
Ground the negative ( −) lead of the voltmeter.
(b) Check the charging circuit as follows:
With the engine running from idle to 2,000 rpm, check the
reading on the ammeter and voltmeter.
Standard amperage 10 A or less
Standard voltage:
at 25° C ’(77°F)14.0 − 15.0 V
at 115°C ’(239° F)13.5 − 14.3 V
If the voltmeter reading is more than standard voltage, replace
the voltage regulator.
If the voltmeter reading is less than the 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.
7. 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
”HI”.
