Diagnosis Procedure

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM - WITHOUT INTELLIGENT KEY SYSTEM ".

1. CHECK GLASS HATCH AJAR SWITCH INPUT SIGNAL 

   With CONSULT

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

   • When glass hatch is open:

     TRNK OPN MNTR: ON 

   • When glass hatch is closed:

     TRNK OPN MNTR: OFF 

   Without CONSULT

   Check voltage between BCM connector M19 terminal 42 and ground.

   Connector	Item	Terminals		Condition	Voltage (V) (Approx.)
   		(+)	(-)
   M19	BCM	42	Ground	Open → Closed	0 → Battery voltage

   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.

      42 - 1: Continuity should exist. 

   4. Check continuity between back door control unit connector B55 (B) terminal 17 and glass hatch ajar switch connector (C) D707 terminal 1.

      17 - 1: Continuity should exist. 

   5. Check continuity between glass hatch ajar switch connector (C) D707 terminal 1 and ground.

      1 - Ground: Continuity should not exist.

      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.
   2. Check continuity between glass hatch ajar switch connector terminal 1 and ground.

      	Terminals	Condition	Continuity
      Glass hatch ajar switch	1 - Ground	Open	Yes
      		Closed	No
