3. INSPECT SPEEDOMETER VOLTAGE
(a) While driving the vehicle at the speed of 10 km/h, check
the voltage between the terminals 16 and 1 of the com-
bination meter assy.
STANDARD: Fluctuation between 10 to 14 V or less is
repeated 7 times within 1 sec.
4. INSPECT VEHICLE SPEED SENSOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
1 and negative (-) lead to terminal 2.
(b) Connect the positive (+) lead from the tester to terminal
3 and the negative (-) lead to terminal 2.
(c) Rotate the shaft.
(d) Check that there is voltage change from approx. 0V to 11
V or more between terminals 2 and 3.
HINT:
The voltage change should be performed 4 times for every rev-
olution is not as specified, replace the sensor.
5. INSPECT TACHOMETER / ON-VEHICLE
(a) Connect a tune-up test tachometer, and start the engine.
(b) Compare the tester and tachometer indications.
DC 13.5 V 25 °C at (77°F):

TION SENSOR CONTINUITY
Check that continuity exists between the terminals 1 and 2
when pressing the sensing part of the lower seat cushion.
If operation is not as specified, replace the sensor.
18. INSPECT LIGHT CONTROL RHEOSTAT
(a) Turn the rheostat knob OFF, and check that there is no
continuity between terminal 5 and 4 (Rheostat knob
turned to fully counterclockwise).
(b) Gradually, turn the rheostat knob from the dark side to
bright side, and check that there is continuity between ter-
minal 5 and 4 (Rheostat knob turned to clockwise).
If operation is not as specified, replace the rheostat.

19. INSPECT INCLINATION SENSOR
(a) The inclination sensor is installed in the combination me-
ter. Inspect the inclination sensor by connecting a battery
positive (+) lead to terminal 11 (IGN+) of the meter con-
nector, and a battery negative (-) lead to terminal 1 (E/G
EARTH).
(b) Check if the voltage between terminal Vcc and GND of the
inclination sensor connector is 5 V.
(c) Check the voltage between terminal OUT and GND when
the bottom surface of the inclination sensor is in a level
position. Also check the voltage when it is inclined back-
ward or forward.
Standard Value:
Bottom surface of sensor is set in a level position:
about 4.5 V
Bottom surface of sensor is inclined:
about 0.5 V

4. INSPECT ENGINE ROOM R/B RELAY CIRCUIT (See
Pase BE-15)
HINT:
The (Headlight, DIM, Tail relay) is built in engine room junction
block. Also the relay is constructed with a relay block that is in
the junction block as a unit. To disconnect the wire harness con-
necting with relay block is impossible. If the relay has a malfunc-
tion, replace it with junction block assembly wire harness to-
gether.
5. Connector disconnected:
INSPECT AUTOMATIC LIGHT CONTROL SENSOR
CIRCUIT
Disconnect the connector from the sensor and inspect the con-
nector on the wire harness side, as shown in the chart.
HINT:

Ignition switch is ON.

Light control switch is in AUTO.

Vehicle's surroundings are bright.

(d) Continue to apply voltage and check that the current
changes to less than 1 A within 4 to 90 seconds.
(e) Disconnect the leads from the terminals.
(f) Approximately 60 seconds later, connect the positive (+)
lead from the battery to terminal 1 and the negative (-)
lead to terminal 4, and check that the window begins to
descend.
If operation is not as specified, replace the motor.
6. INSPECT JAM PROTECTION LIMIT SWITCH OPERA-
TION
(a) Connect the positive (+) lead from the ohmmeter to termi-
nal 2 and the negative (-) lead to terminal 5.
(b) Connect the positive (+) lead from the battery to terminal
1 and the negative (-) lead to terminal 4.
(c) Check that the continuity exists when the window goes
up.
(d) Check that the no continuity exists when the window is in
the fully closed position.
If operation is not as specified, replace the motor.
NOTICE:
If connecting the wire harness wrongly, the sensor might
be damaged so caution is necessary.
7. INSPECT JAM PROTECTION PULSE SWITCH OP-
ERATION
(a) Connect the positive (+) lead from the TOYOTA electrical
tester to terminal 3 and the negative (-) lead to terminal
5.
(b) Connect the positive (+) lead from the battery to terminal
1 and the negative (-) lead to terminal 4.
(c) Check that pulse is generated during the motor running.
(d) Reverse the polarity and check that pulse is generated.
