Diagnosis Procedure

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM - VEHICLE SECURITY SYSTEM ".

1. CHECK GLASS HATCH AJAR SWITCH INPUT SIGNAL

   With CONSULT-III

   Check glass hatch ajar switch "GLASS HATCH SW" in DATA MONITOR mode with CONSULT-III.

   • When glass hatch is open:

     GLASS HATCH SW :ON 

   • When glass hatch is closed:

     GLASS HATCH SW :OFF 

   Without CONSULT-III

   1. Turn ignition switch OFF.
   2. Check voltage between BCM connector M19 terminals 42 and ground.
      VOLTAGE SPECIFICATION
      
      

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

      Is the inspection result normal? 

      YES: Glass hatch ajar switch circuit is OK.

      NO: GO TO  2

2. CHECK GLASS HATCH AJAR SWITCH CIRCUIT
   1. Disconnect glass hatch ajar switch and BCM.
   2. Check continuity between BCM connector M19 (A) terminal 42 and glass hatch ajar switch connector D503 (B) terminal 1.

      42 - 1 :Continuity should exist 

   3. Check continuity between BCM connector M19 (A) terminal 42 and ground.

      42 - 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

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

   CONTINUITY SPECIFICATION
   
   

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

   Is the inspection result normal? 

   YES: Refer to "INTERMITTENT INCIDENT ".

   NO: Replace glass hatch ajar switch.
