DIAGNOSIS AND REPAIR WORKFLOW

BASIC INSPECTION

DIAGNOSIS AND REPAIR WORKFLOW

Work Flow

INFOID:0000000005255990

DETAILED FLOW

1.

OBTAIN INFORMATION ABOUT SYMPTOM

Interview the customer to obtain the malfunction information (conditions and environment when the malfunc-

tion occurred) as much as possible when the customer brings the vehicle in.

>> GO TO 2

2.

REPRODUCE THE MALFUNCTION INFORMATION

Check the malfunction on the vehicle that the customer describes.

Inspect the relation of the symptoms and the condition when the symptoms occur.

>> GO TO 3

3.

IDENTIFY THE MALFUNCTIONING SYSTEM WITH “SYMPTOM DIAGNOSIS”

Use “Symptom diagnosis” from the symptom inspection result in step 2 and then identify where to start per-

forming the diagnosis based on possible causes and symptoms.

>> GO TO 4

4.

IDENTIFY THE MALFUNCTIONING PARTS WITH “COMPONENT DIAGNOSIS”

Perform the diagnosis with “Component diagnosis” of the applicable system.

>> GO TO 5

5.

REPAIR OR REPLACE THE MALFUNCTIONING PARTS

Repair or replace the specified malfunctioning parts.

>> GO TO 6

6.

FINAL CHECK

Check that malfunctions are not reproduced when obtaining the malfunction information from the customer,

referring to the symptom inspection result in step 2.
Are the malfunctions corrected?

YES

>> Inspection End.

NO

>> GO TO 3

< FUNCTION DIAGNOSIS >

POWER WINDOW SYSTEM

POWER WINDOW OPERATION

• Power window system is operable during the retained power operation timer after turning ignition switch ON

and OFF.

• Main power window and door lock/unlock switch can open/close all windows.

• Power window and door lock unlock switch RH & rear power window switches LH and RH can open/close

the corresponding windows.

POWER WINDOW AUTO-OPERATION (FRONT LH & RH)

• AUTO UP/DOWN operation can be performed when main power window and door lock/unlock switch &

power window and door lock/unlock switch RH turns to AUTO.

• Encoder continues detecting the movement of power window motor and transmits to power window switch

as the encoder pulse signal while power window motor is operating.

• Power window switch reads the changes of encoder signal and stops AUTO operation when door glass is at

fully opened/closed position.

• Power window motor is operable in case encoder is malfunctioning.

RETAINED POWER OPERATION

• Retained power operation is an additional power supply function that enables power window system to oper-

ate during the 45 seconds even when ignition switch is turned OFF

Retained power function cancel conditions

• Front door CLOSE (door switch OFF)

→

OPEN (door switch ON).

• When ignition switch is ON.

• When timer time passes. (45 seconds)

POWER WINDOW LOCK

Ground circuit inside main power window and door lock/unlock switch shuts off when power window lock

switch is ON. This inhibits power window switch operation except with the main power window and door lock/

unlock switch.

ANTI-PINCH OPERATION (FRONT LH & RH)

• Pinch foreign material in the door glass during AUTO-UP operation, and it is the anti-pinch function that low-

ers the door glass 150 mm (5.91 in) or 2 seconds when detected.

• Encoder continues detecting the movement of power window motor and transmits to power window switch

as the encoder pulse signal while power window motor is operating.

• Resistance is applied to the power window motor rotation that changes the frequency of encoder pulse sig-

nal if foreign material is trapped in the door glass.

• Power window switch controls to lower the window glass for 150 mm (5.91 in) or 2 seconds after it detects

encoder pulse signal frequency change.

OPERATION CONDITION

• When all door glass AUTO-UP operation is performed (anti-pinch function does not operate just before the

door glass closes and is fully closed)

NOTE:

Depending on environment and driving conditions, if a similar impact or load is applied to the door glass, it

may lower.

KEY CYLINDER SWITCH OPERATION

Hold the driver’s door key cylinder to the LOCK or UNLOCK direction for more than 1 second to OPEN or

CLOSE front power windows when ignition switch is OFF. In addition, it stops when key position is moved to

NEUTRAL when operating.

OPERATION CONDITION

• Ignition switch OFF

• Hold driver’s door key cylinder to LOCK position for more than 1 second to perform CLOSE operation of the

door glass.

• Hold driver’s door key cylinder to UNLOCK position for more than 1 second to perform OPEN operation of

the door glass.

KEYLESS POWER WINDOW DOWN OPERATION (FRONT LH & RH)

Front power windows open when the unlock button on Intelligent Key or keyfob is activated and kept pressed
for more than 3

(NOTE)

seconds with the ignition switch OFF. The windows keep opening if the unlock button is

continuously pressed.

The power window opening stops when the following operations are performed:

• When the unlock button is kept pressed more than 15 seconds.

• When the ignition switch is turned ON while the power window opening is operated.

• When the unlock button is released.

While retained power operation is activated, keyless power window down function cannot be operated.

NOTE:

Keyless power window down operation mode can be changed by “PW DOWN SET” mode in “WORK SUP-

PORT”. Refer to

BCS-25, "INTELLIGENT KEY : CONSULT-III Function (BCM - INTELLIGENT KEY)"

with

Intelligent Key or

BCS-20, "MULTIREMOTE ENT : CONSULT-III Function (BCM - MULTIREMOTE ENT)"

with

remote keyless entry system.

NOTE:

Use CONSULT-III to change settings.
