Diagnosis Procedure

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

1. PINCH STRIP SIGNAL INSPECTION 
   1. Turn ignition switch OFF.
   2. While operating the pinch strip, check voltage between back door control unit connector B55 terminals 19, 20 and ground.

      Terminals		Measuring condition	Voltage (V) (Approx.)
      (+)	(-)
      19	Ground	Pinch strip RH operation	0
      		Other	5
      20	Ground	Pinch strip LH operation	0
      		Other	5

      Is the inspection result normal? 

      YES: Switch is OK.

      NO: GO TO 2

2. PINCH STRIP CIRCUIT INSPECTION 
   1. Disconnect pinch strip and back door control unit connector.
   2. Check continuity between back door control unit connector (A) B55 terminals 5, 19 (RH) or 5, 20 (LH) and pinch strip connector (B) D715 (RH), D517 (LH) terminals 1, 2.

      RH: 1 - 19: Continuity should exist. 

      LH: 1 - 20: Continuity should exist. 

      RH and LH 2 - 5: Continuity should exist. 

   3. Check continuity between pinch strip connector (B) D715 (RH), D517 (LH) terminals 1, 2 and ground.

      1 - Ground: Continuity should not exist. 

      2 - Ground: Continuity should not exist.

      Is the inspection result normal? 

      YES: Replace the pinch strip.

      NO: Repair the harness between the pinch strip and the back door control unit.
