Diagnosis Procedure

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM ".

1. CHECK FRONT DOOR REQUEST SWITCH 

   With CONSULT 

   Check front door request switch ("DR REQ SW" or "AS REQ SW") in "DATA MONITOR" mode.

   Monitor item	Condition
   DR REQ SW AS REQ SW	Front door request switch is pressed: ON
   	Front door request switch is released: OFF

   Without CONSULT 

   1. Turn ignition switch OFF.
   2. Check voltage between Intelligent Key unit harness connector M70 terminals 5, 25 and ground.

      Connector	Item	Terminals		Condition	Voltage (V) (Approx.)
      		(+)	(-)
      M70	Front door request switch LH	5	Ground	Door request switch is pressed ↓ Door request switch is released	0 ↓ Battery voltage
      	Front door request switch RH	25

      Is the inspection result normal? 

      YES: Front door request switch is OK.

      NO: GO TO 2

2. CHECK FRONT DOOR REQUEST SWITCH CIRCUIT 
   1. Turn ignition switch OFF.
   2. Disconnect Intelligent Key unit and front door request switch connectors.
   3. Check continuity between Intelligent Key unit harness connector (A) M70 terminals 5 (driver door), 25 (passenger door) and front door request switch harness connector (B) D16 (LH), D116 (RH) terminal 1.

      Driver side 5 - 1: Continuity should exist. 

      Passenger side 25 - 1: Continuity should exist. 

   4. Check continuity between Intelligent Key unit harness connector (A) M70 terminals 5 (driver door), 25 (passenger door) and ground.

      5 - Ground: Continuity should not exist. 

      25 - Ground: Continuity should not exist.
