PWBD BRANCH LINE CIRCUIT

Diagnosis Procedure

INFOID:0000000009175174

1.

CHECK CONNECTOR

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Check the following terminals and connectors for damage, bend and loose connection (unit side and con-

nector side).

-

Automatic back door control module

-

CAN gateway (Models with around view monitor)

Is the inspection result normal?

YES-1 >> Models with around view monitor: GO TO 2.

YES-2 >> Models without around view monitor: GO TO 3.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1. Disconnect the connector of CAN gateway.

2. Check the continuity between the CAN gateway harness connector terminals.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Check the harness and repair the root cause (CAN communication circuit 2 side).

3.

CHECK HARNESS FOR OPEN CIRCUIT

1. Connect the connector of CAN gateway. (Models with around view monitor)

2. Disconnect the connector of automatic back door control module.

3. Check the resistance between the automatic back door control module harness connector terminals.

Is the measurement value within the specification?

YES

>> GO TO 4.

NO

>> Replace the body harness.

4.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the automatic back door control module. Refer to

DLK-162,

"AUTOMATIC BACK DOOR CONTROL UNIT : Diagnosis Procedure"

.

Is the inspection result normal?

YES (Present error)>>Replace the automatic back door control module. Refer to

DLK-321, "Removal and

Installation"

.

YES (Past error)>>Error was detected in the automatic back door control module branch line.

NO

>> Repair the power supply and the ground circuit.
