2. INSPECT PTC OPERATION
Driver 's Door
(a) Disconnect the connector from the master switch.
(b) Connect the positive (+) lead from the battery to terminal 9
and the negative (±) lead to terminal 10 on the wire harness
side connector and raise the window to the fully closed
position.
(c) Continue to apply voltage, check that there is a PTC
operation noise within approximately 4 to 90 seconds.
(d) Reverse the polarity, check that the window begins to
descend within approximately 60 seconds.
If operation is not as specified, replace the motor.
Passenger 's Door
(a) Disconnect the connector from the power window switch.
(b) Connect the positive (+) lead from the battery to terminal 2
and the negative (±) lead to terminal 5 on the wire harness
side connector, and raise the window to the fully closed
position.
(c) Continue to apply voltage, check that there is a PTC
operation noise within approximately 4 to 90 seconds.
(d) Reverse the polarity, check that the window begins to
descend within approximately 60 seconds.
If operation is not as specified, replace the motor. BE±72

SLIDE MOTOR INSPECTION
1. INSPECT MOTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal 2
and the negative (±) lead to terminal 1, check that the motor
turns counterclockwise.
(b) Reverse the polarity, check that the motor turns clockwise.
If operation is not as specified, replace the motor.
2. INSPECT PTC THERMISTOR OPERATION
(a) Separate power seat adjuster from front seat.
(b) Connect the positive (+) lead from the battery to terminal 2,
the positive (+) lead from the ammeter to terminal 1, and the
negative (±) lead to battery negative (±) terminal, and move
the seat front end position.
(c) Continue to apply voltage, check the current changes to less
than 1 ampere within 4 to 90 seconds.
(d) Disconnect the lead from terminals.
(e) Approximately 60 seconds later, connect the positive (+) lead
from battery to terminal 1 and the negative (±) lead to terminal
2, check that the seat begins to move backwards.
If operation is not as specified, replace the motor. BE±76

RECLINING MOTOR INSPECTION
1. INSPECT MOTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal 2
and negative (±) lead to terminal 1 and check that the motor
turns counterclockwise.
(b) Reverse the polarity, check that the motor turns clockwise.
If operation is not as specified, replace the motor.
2. INSPECT PTC THERMISTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal 2.
(b) Connect the positive (+) lead from the ammeter to terminal 1
and the negative (±) lead to battery negative (±) terminal.
(c) Check that the seat back is reclined to the most forward
position.
(d) Continue to apply voltage, check the current change to less
