Diagnosis Procedure

INFOID:0000000005146999

Regarding Wiring Diagram information, refer to 

DLK-157, "Wiring Diagram — POWER DOOR LOCK SYS-

TEM —"

.

NOTE:

Repair any front door lock actuator RH malfunction before proceeding with this diagnosis.

1.

CHECK GLASS HATCH SWITCH

1. Turn ignition switch OFF.

2. Insure front door lock actuator RH is in the unlock position.

3. Check continuity between glass hatch switch terminal 2 and ground.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> GO TO 3.

2.

CHECK HARNESS CONTINUITY

1. Disconnect glass hatch switch.

2. Disconnect BCM.

3. Check continuity between BCM connector M18 (A) terminal 30

and glass hatch switch connector D706 (B) terminal 2.

4. Check continuity between BCM connector M18 (A) terminal 30

and ground.

Is the inspection result normal?

YES

>> Glass hatch switch circuit is OK.

NO

>> Repair or replace harness.

3.

CHECK GLASS HATCH SWITCH

1. Disconnect glass hatch switch.

2. Check continuity between glass hatch switch harness connector

D706 terminal 1 and ground.

Is the inspection result normal?

YES

>> Replace glass hatch switch.

NO

>> GO TO 4.

Diagnosis Procedure

INFOID:0000000005147000

Regarding Wiring Diagram information, refer to 

DLK-199, "Wiring Diagram—AUTOMATIC BACK DOOR SYS-

TEM—"

.

1.

CHECK GLASS HATCH AJAR SWITCH INPUT SIGNAL

With CONSULT-III

Check glass hatch ajar switch ("TRNK OPN MNTR") in DATA MONITOR mode with CONSULT–III.

• When glass hatch is open:

• When glass hatch is closed:

Without CONSULT-III

Check voltage between BCM connector M19 terminal 42 and ground.

Is the inspection result normal?

YES

>> System is OK.

NO

>> GO TO 2

2.

CHECK GLASS HATCH AJAR SWITCH CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect glass hatch ajar switch, BCM and back door control unit.

3. Check continuity between BCM connector (A) M19 terminal 42 and glass hatch ajar switch connector (C)

D707 terminal 1.

4. Check continuity between back door control unit connector B55

(B) terminal 17 and glass hatch ajar switch connector (C) D707

terminal 1.

5. Check continuity between glass hatch ajar switch connector (C)

D707 terminal 1 and ground.

Is the inspection result normal?

YES

>> GO TO 3

NO

>> Repair or replace harness.

3.

CHECK GLASS HATCH AJAR SWITCH

1. Disconnect glass hatch ajar switch connector.
