INSPECT MIRROR POSITION SENSORS OPERATION
HINT:
Strip off the vinyl tape of the connector and remove terminals
2, 3, 6, 7 and 9 from the connector housing.
(a) Connect a series of three 1.5 V dry cell batteries.
(b) Connect the positive (+) lead from the dry cell batteries to
terminal 7 and the negative (-) lead to terminal 6.
(c) Connect the positive (+) lead from the voltmeter to termi-
nal 9 and the negative (-) lead to terminal 6.
(d) Apply Battery voltage to terminals 2 and 3, then check
that the voltage gradually changes according to the table
below while the mirror moves between the uppermost
position and lowermost position.

(e) Disconnect the 4 leads of the battery and voltmeter.
(f) Connect the positive (+) lead from the voltmeter to termi-
nal 8 and negative (-) lead to terminal 6.
(g) Apply Battery voltage to terminals 2 and 1, then inspect
that the voltage gradually changes according to the table
below while the mirror moves between the left-most posi-
tion and right-most position.

INSPECT JAM PROTECTION LIMIT SWITCH OPERA-
TION
(a) Connect the negative (-) lead from the ohmmeter to ter-
minal 5 and the positive (+) lead to terminal 4.
(b) Connect the positive (+) lead from the battery to terminal
1 and the negative (-) lead to terminal 2.
(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.
15. Driver 's Door (Window Down):
INSPECT JAM PROTECTION LIMIT SWITCH OPERA-
TION
(a) Connect the negative (-) lead from the ohmmeter to ter-
minal 5 and the positive (+) lead to terminal 4.
(b) Connect the positive (+) lead from the battery to terminal
2 and the negative (-) lead to terminal 1.
(c) Check that the continuity exists when the window goes
down.
(d) Check that the no continuity exists when the window is in
the fully opened 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.
16. Driver 's Door:
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 2.
(c) Check that pulse is generated during the motor running.

be damaged so caution is necessary.
17. INSPECT JAM PROTECTION FUNCTION
NOTICE:
Never, ever be caught any part of your body when check-
ing.
HINT:
In case of performing resetting of the limit switch, do checking

(b) Checking of the operation of the jam protection function:
(1) Move up the window with AUTO up operation and
check that the window will go down when it touches
the handle of the hammer stetted.
(2) Confirm that the window will then stop going down
about 200 mm.
