OUTSIDE KEY ANTENNA
OUTSIDE KEY ANTENNA
DescriptionINFOID:0000000001507417
Detects whether the Intelligent Key is in the operating range of the outside antennas.
Front outside antennas are integrated in front outside door handles (driver side, passenger side) to allow lock-
ing and unlocking of door locks including back door (hatchback) and trunk lid (sedan) when the Intelligent Key
is present.
Rear bumper antenna is mounted on the rear bumper and is used to allow the locking and unlocking of door
locks including back door (hatchback) and trunk lid (sedan) when the Intelligent Key is present.
Component Function CheckINFOID:0000000001507418
1.CHECK DOOR REQUEST SWITCH
Check that door request switches operate normally.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Inspect door request switches. Refer to XX-XX, "*****"
.
2.CHECK FRONT ANTENNAS FUNCTION
Be sure that Intelligent Key is in each outside key antenna detection range.
Does door lock/unlock when each request switch is pressed?
YES >> Outside key antenna is OK.
NO >> Refer to DLK-132, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000001507419
1.CHECK OUTSIDE KEY ANTENNA INPUT SIGNAL
1. Turn ignition switch OFF.
2. Check signal between Intelligent Key unit connector M52 termi-
nals 17, 19, 37 and ground with an oscilloscope.
