Fail-safe

INFOID:0000000007563123

FAIL-SAFE CONTROL

Switches to fail-safe control when malfunction is detected in encoder signal that detects up/down speed and
direction of door glass. Switches to fail-safe control when error beyond regulation value is detected between
the fully closed position and the actual position of the glass.

It changes to condition before initialization and the following functions do not operate when switched to fail-
safe control.
• Auto-up operation
• Anti-pinch function
• Retained power function

Perform initial operation to recover when switched to fail-safe mode. However, it switches back to fail-safe
control when malfunction is found in power window switch or front power window motor.

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.

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.

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.

IDENTIFY THE MALFUNCTIONING PARTS WITH “DTC/CIRCUIT DIAGNOSIS”

Perform the diagnosis with “DTC/CIRCUIT DIAGNOSIS” of the applicable system.

>> GO TO 5.

REPAIR OR REPLACE THE MALFUNCTIONING PARTS

Repair or replace the specified malfunctioning parts.

>> GO TO 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
