SQUEAK AND RATTLE TROUBLE DIAGNOSES
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area c an often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sun-visor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the pos ition the seat is in and the load placed on the seat when
the noise is present. These conditions should be dupl icated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of thes e incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted under-hood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the \
vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT
ough understanding of system operation. Then you will be able to use the appropriate equipment and follow
the correct test procedure.
You may have to simulate vehicle vibrations while test ing electrical components. Gently shake the wiring har-
ness or electrical component to do this.
NOTE:
Refer to “How to Check Terminal” to probe or check terminal.
Testing for “Opens” in the Circuit
Before you begin to diagnose and test the system, you should rough sketch a schematic of the system. This
will help you to logically walk through the diagnosis process. Drawing the sketch will also reinforce your work-
ing knowledge of the system.
CONTINUITY CHECK METHOD
The continuity check is used to find an open in the circ uit. The digital multimeter (DMM) set on the resistance
function will indicate an open circuit as over limit (no beep tone or no ohms symbo\
l). Make sure to always start
with the DMM at the highest resistance level.
To help in understanding the diagnosis of open circui ts, please refer to the previous schematic.
 Disconnect the battery negative cable.
 Start at one end of the circuit and work your way to the other end. (At the fuse block in this example)
 Connect one probe of the DMM to the fuse block terminal on the load side.
 Connect the other probe to the fuse block (power) side of SW1. Little or no resistance will indicate that por-
tion of the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an over
limit or infinite resistance condition. (point A)
 Connect the probes between SW1 and the relay. Little or no resistance will indicate that portion of the circuit
has good continuity. If there were an open in the circuit, t he DMM would indicate an over limit or infinite resis-
tance condition. (point B)
 Connect the probes between the relay and the solenoid. Little or no resistance will indicate that portion of the
circuit has good continuity. If there were an open in the ci rcuit, the DMM would indicate an over limit or infi-
nite resistance condition. (point C)
Any circuit can be diagnosed using the approach in the previous example.
VOLTAGE CHECK METHOD
To help in understanding the diagnosis of open circui ts please refer to the previous schematic.
In any powered circuit, an open can be found by methodica lly checking the system for the presence of voltage.
This is done by switching the DMM to the voltage function.
 Connect one probe of the DMM to a known good ground.
 Begin probing at one end of the circuit and work your way to the other end.
 With SW1 open, probe at SW1 to check for voltage.
voltage; open is further down the circuit than SW1.
no voltage; open is between fuse block and SW1 (point A).
 Close SW1 and probe at relay.
voltage; open is further down the circuit than the relay.
no voltage; open is between SW1 and relay (point B).
OPEN A circuit is open when there is no continuity through a section of the circuit.
SHORT There are two types of shorts.
 SHORT CIRCUIT
When a circuit contacts another circuit and causes the normal resistance to
change.
 SHORT TO GROUND When a circuit contacts a ground source and grounds the circuit.

When the ignition switch is turned to the OFF position from ON or START position.
Power is supplied for 45 seconds
 through BCM terminal 53
 to power window main switch terminal 10
 to rear power window switch (LH and RH) terminals 1.
When power and ground are supplied, the BCM conti nues to be energized, and the power window can be
operated.
The retained power operation is canceled when the driver or passenger side door is opened.
RAP signal period can be changed by CONSULT-III. Refer to GW-26, "
CONSULT-III Function".
ANTI-PINCH SYSTEM
Power window main switch and front power window switch (passenger side) monitors the power window motor
operation and the power window position (full closed or other) for driver side and passenger side power win-
dow by the signals from encoder and limit switch in front power window motor (driver side and passenger
side).
When power window main switch detects inte rruption during the following close operation,
 automatic close operation when igniti on switch is in the “ON” position
 automatic close operation during retained power operation
 manual close operation during retained power operation
power window main switch or front power window swit ch (passenger side) controls each power window motor
for open and the power window will be lowered about 150 mm (5.91 in).
POWER WINDOW CONTROL BY THE KEY CYLINDER SWITCH
When ignition key switch is OFF, front power window can be opened or closed by turning the key cylinder
switch UNLOCK / LOCK position more than 1.5 second over condition.
 Power window can be opened as the door key cylinder is kept fully turning to the UNLOCK position.
 Power window can be closed as the door key cylinder is kept fully turning to the LOCK position.
The power window DOWN stops when the following operations are carried out.
 While performing open / close the window, power window is stopped at the position as the door key cylinder is placed on NEUTRAL.
 When the ignition switch is turned ON while the power window DOWN is operated.
CAN Communication System DescriptionINFOID:0000000001327964
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication s peed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CA N communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
