2. Magazine
3. Changer1. Con®rm the magazine is pushed completely.
2. Inspect magazine.
(Refer to testing magazines and discs.)
3. Remove the changer for repair.
Testing magazines and discs
1. Con®rm discs are installed correctly into the magazine (not upside down).
2. Visually inspect/compare the customer's discs with each other and other discs.
Identify any of the following conditions:
+Discs with a large outside diameter. [Normal size is 120 mm (4.72 in).]
+Discs with rough or lipped edges.
+Discs with excessive thickness [Normal size is 1.2 mm (0.047 in).]
+Discs with scratches, abrasions, or pits on the surface.
+Discs with grease/oil, ®ngerprints, foreign material.
+Discs are warped due to excessive heat exposure.
3. Slide/place the discs in and out of the various magazine positions.
Identify any discs and/or positions that require additional force for placement/ejection. If interference
(sticking, excessive tensions) is found, replace the magazine or the discs.
Note:
+Discs which are marginally out of speci®cation (ex. dirty, scratched and so on) may play correctly
on a home stereo.
However, when used in the automotive environment skipping may occur due to the added vehicle
movement and/or vibration due to road conditions. Autochangers should not be replaced when
discs are at fault.
+Use a soft damp cloth to wipe the discs starting from the center outward in radial direction. Never
use chemical cleaning solutions to clean the discs.

MANUAL OPERATION
NOTE:
Numbers in parentheses are terminal numbers, when power window switch is pressed in the UP and DOWN
positions respectively.
Driver side
When the driver side switch in the power window main switch is pressed in the up position, power is supplied
+to driver side power window regulator terminal (j
2,j1)
+through power window main switch terminal (j
9,j8).
Ground is supplied
+to driver side power window regulator terminal (j
1,j2)
+through power window main switch terminal (j
8,j9).
Then, the motor raises or lowers the window until the switch is released.
Passenger side
MAIN SWITCH OPERATION
Power is supplied
+through power window main switch (j
5,j6)
+to front power window sub-switch (j
3,j4).
The subsequent operation is the same as the sub-switch operation.
SUB-SWITCH OPERATION
Power is supplied
+through front power window sub-switch (j
1,j2)
+to passenger side power window regulator (j
2,j1).
Ground is supplied
+to passenger side power window regulator (j
1,j2)
+through front power window sub-switch (j
2,j1)
+to front power window sub-switch (j
4,j3)
+through power window main switch (j
6,j5).
Then, the motor raises or lowers the window until the switch is released.
Rear door
Rear door windows will raise and lower in the same manner as passenger side door window.
AUTO OPERATION
The power window AUTO feature enables the driver to open or close the driver's window without holding the
window switch in the respective position.
When the AUTO switch in the main switch is pressed and released, the driver's window will travel to the fully
open or closed position.
POWER WINDOW LOCK
The power window lock is designed to lock operation of all windows except for driver's door window.
When the lock switch is pressed to lock position, ground of the sub-switches in the power window main switch
is disconnected. This prevents the power window motors from operating.

How to Read Harness Layout
Example:
G2E1B/6: ASCD ACTUATOR
Connector color / Cavity
Connector number
Grid reference
The following Harness Layouts use a map style grid to help locate connectors on the drawings:
+Main Harness
+Engine Room Harness (Engine Compartment)
To use the grid reference
1) Find the desired connector number on the connector list.
2) Find the grid reference.
3) On the drawing, ®nd the crossing of the grid reference letter column and number row.
4) Find the connector number in the crossing zone.
5) Follow the line (if used) to the connector.
CONNECTOR SYMBOL
Main symbols of connector (in Harness Layout) are indicated in the below.
Connector typeWater proof type Standard type
Male Female Male Female
+Cavity: Less than 4
+Relay connector
+Cavity: From 5 to 8
+Cavity: More than 9
