Description

INFOID:0000000003646514

The automatic back door control unit receives the pulse signals from encoders A and B that occurred due to
synchronization with the back door operation. The automatic back door control unit calculates the back door
position, operation direction, and operation speed according to the received pulse signals.

Component Function Check

INFOID:0000000003443886

1.

CHECK FUNCTION

Check encoder (“ENCODER A”, “ENCODER B”) in Data Monitor mode.

Is the inspection result normal?

YES

>> Encoder is OK.

NO

>> Refer to 

DLK-163, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000003443887

1.

CHECK ENCODER POWER SUPPLY

1.

Turn ignition switch OFF.

2.

Disconnect automatic back door unit connector.

3.

Check voltage between automatic back door unit harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

CHECK ENCODER POWER SUPPLY CIRCUIT

1.

Disconnect automatic back door control unit connector.

2.

Check continuity between automatic back door control unit harness connector and automatic back door
unit harness connector.

3.

Check continuity between automatic back door control unit harness connector and ground.

Is the inspection result normal?

YES

>> Replace automatic back door control unit. Refer to 

DLK-379, "Removal and Installation"

.

NO

>> Repair or replace harness.
