WorkFlow

INFOID:0000000001694237

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

ADDITIONAL SERVICE WHEN REMOVING BATTERY NEGATIVE TERMINAL : Spe-
cial Repair Requirement

INFOID:0000000001693961

INITIALIZATION PROCEDURE

1.

Disconnect battery minus terminal or power window main switch connector. Reconnect it after a minute or
more. 

2.

Turn ignition switch ON.

3.

Operate power window switch to fully open the window. (This operation is unnecessary if the window is
already fully open)

4.

Continue pulling the power window switch UP (AUTO-UP operation). Even after glass stops at fully closed
position, keep pulling the switch for 3 seconds or more. 

5.

Inspect anti-pinch function.

CHECK ANTI-PINCH FUNCTION

1.

Fully open the door window.

2.

Place a piece of wood near fully closed position.

3.

Close door glass completely with AUTO-UP.

• Check that glass lowers for approximately 150 mm or 2 seconds without pinching piece of wood and stops.
• Check that glass does not rise when operating the power window main switch while lowering.

CAUTION:

• Do not check with hands and other part of body because they may be pinched. Do not get pinched.
• Check that AUTO-UP operates before inspection when system initialization is performed.
•  It may switch to fail-safe mode if open/close operation is performed continuously. Perform initial

setting in that situation. Refer to 

PWC-71, "Fail Safe"

• Perform initial setting when auto-up operation or anti-pinch function does not operate normally.
• Finish initial setting. Otherwise, next operation cannot be done.
