INSPECT ELECTRICAL RETRACT MOTOR CONTINU-
ITY

(a)

Connect the positive (+) lead from the battery to terminal
2 and negative (–) lead to terminal 1, check that the no
continuity exists in folding position.

(b)

Reverse the polarity, check that no continuity exists in
driving position.

If operation is not as specified, replace the mirror assembly.

13.

INSPECT ELECTRICAL RETRACT MOTOR CONTINU-
ITY
At drive position:

(a)

Connect the positive (+) lead from the battery to terminal
2 and negative (–) lead to terminal 1, check that continuity
exists in folding position.

(b)

Reverse the polarity, check that no continuity exists in
driving position.

If operation is not as specified, replace the mirror assembly.

14.

INSPECT ELECTRICAL RETRACT MOTOR CONTINU-
ITY
Between drive position and retract position:

(a)

Connect the positive (+) lead from the battery to terminal
2 and negative (–) lead to terminal 1, check that continuity
exists in folding position.

(b)

Reverse the polarity, check that no continuity exists in
driving position.

If operation is not as specified, replace the mirror assembly.

15.

INSPECT MIRROR MOTOR OPERATION

(a)

Connect the positive (+) lead from the battery to terminal
2 and negative (–) lead to terminal 1.

(b)

Check that the motor turns (moves to folding position).

NOTICE:
These tests must be performed quickly (within 5 – 10 se-
conds) to prevent the coil from burning out.

(c)

Connect the positive (+) lead from the battery to terminal
1 and negative (–) lead to terminal 2.

(d)

Check that the motor turns (moves to driving position).

NOTICE:
These tests must be performed quickly (within 5 – 10 se-
conds) to prevent the coil from burning out.
If operation is not as specified, replace the mirror assembly.

INSPECTION

1.

INSPECT DRIVER’S HEIGHT ADJUSTABLE ANCHOR
MOTOR AND SENSOR OPERATION

(a)

Connect the positive (+) lead from the battery to terminal
4 and the negative (–) lead to terminal 1, and check that
the slider moves upward.

(b)

Reverse the polarity and check that the slider moves
downward.

If operation is not as specified, replace the height adjustable an-
chor motor.

2.

Inspection using an ammeter:
INSPECT DRIVER’S HEIGHT ADJUSTABLE ANCHOR
MOTOR AND SENSOR PTC THERMISTOR OPERA-
TION

(a)

Connect the positive (+) lead from the battery to terminal
1, the positive (+) lead from the ammeter to terminal 4,
and the negative (–) lead to battery negative (–) terminal,
then move the slider to end position.

(b)

Continue to apply voltage and check the current changes
to less than 0.1 A within 6 to 46 seconds.

(c)

Disconnect the leads from terminals.

(d)

Approximately 60 seconds later, connect the positive (+)
lead from battery to terminal 4 and the negative (–) lead
to terminal 1, and check that the slider moves to the oppo-
site side.

If operation is not as specified, replace the height adjustable an-
chor motor.

Inspection using an ammeter with a current–measur-
ing probe:
INSPECT DRIVER’S HEIGHT ADJUSTABLE ANCHOR
MOTOR AND SENSOR PTC THERMISTOR OPERA-
TION

(a)

Connect the positive (+) lead from the battery to terminal
1 and the negative (–) lead to terminal 4.

(b)

seconds.

(d)

Disconnect the leads from terminals.

(e)

Approximately 60 seconds later, reverse the polarity, and
check that the slider moves to the opposite side.

If operation is not as specified, replace the height adjustable an-
chor motor.
