Check Outside Key Antenna

Push each door request switch, and use an oscilloscope to check voltage waveform of harness between Intelligent Key unit connector M34 terminals 17 (back door), 19 (driver and rear LH door), and 37 (passenger and rear RH door) and ground.

Terminal (Wire color)		Condition	Signal (Reference value)
(+)	(-)
Back door: 17 (L)	Ground	Push each door request switch
Driver, rear LH: 19 (SB)
Passenger, rear RH 37 (G)

OK or NG 

OK : GO TO 2.

NG : GO TO  3.

1. Disconnect each outside key antenna connector.
2. Check the following.
   • Check continuity between door mirror (outside key antenna) connector D2 (driver side), D32 (passenger side) terminals 14 and 15
   • Check continuity between outside key antenna D62 (rear door LH), D82 (rear door RH), D116 (back door) terminals 1 and 2

     Driver side, Passenger side 

     14 - 15 : Continuity should exist. 

     Back door, Rear door 

     1 - 2 : Continuity should exist. 

OK or NG 

OK : GO TO 3.

NG : Replace outside key antenna.
