lto front combination lamp RH terminal 1
lto side turn signal lamp RH terminal 1 and
lto rear combination lamp RH terminal 2.
Ground is supplied
lto front combination lamp RH and LH terminals 2
lto side turn signal lamp RH and LH terminals 2 and
lto rear combination lamp RH and LH terminals 3
lthrough ground E21, E41 and E61.
The BCM also supplies input to combination meter terminals 11 and 12 through the CAN communication. This
input is processed by unified meter control unit in combination meter, which in turn supplies ground to the left
and right turn signal indicator lamps.
With power and input supplied, BCM controls flashing of hazard warning lamps.
REMOTE KEYLESS ENTRY SYSTEM OPERATION

ELECTRICAL UNITS LOCATION
Fuse
EKS00LJB
lIf fuse is blown, be sure to eliminate cause of incident before
installing new fuse.
lUse fuse of specified rating. Never use fuse of more than speci-
fied rating.
lDo not partially install fuse; always insert it into fuse holder prop-
erly.
lRemove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is not
used for a long period of time.
Fusible LinkEKS00LJC
A melted fusible link can be detected either by visual inspection or by feeling with finger tip. If its condition is
questionable, use circuit tester or test lamp.
CAUTION:
lIf fusible link should melt, it is possible that critical circuit (power supply or large current carrying
circuit) is shorted. In such a case, carefully check and eliminate cause of incident.
lNever wrap outside of fusible link with vinyl tape.
lNever let fusible link touch any other wiring harness, vinyl or rubber parts.
Circuit Breaker (Built Into BCM)EKS00LJD
For example, when current is 30A, the circuit is broken within 8 to 20
seconds.
A circuit breaker is used for the following systems:
lPower seat
lPower windows
lPowerdoorlocks
lRemote keyless entry system
lPower sunroof
lRear window wiper
