The unified meter and A/C amp. which received the turn indicator signal makes a left and right turn signal indi-
cator turn on in combination meter.
With power and input supplied, the BCM controls the flashing of the hazard warning lamps.
REMOTE CONTROL ENTRY SYSTEM OPERATION
Power is supplied at all times
●
through 50A fusible link [letter F, located in fuse and fusible link block]
●
to BCM (body control module) terminal 55
●
through 10A fuse [No. 18, located in fuse block (J/B)]
●
to BCM (body control module) terminal 42
●
through 10A fuse [No. 19, located in fuse block (J/B)]
●
to unified meter and A/C amp. terminal 21
●
through 10A fuse [No. 21, located in fuse block (J/B)]
●
to combination meter terminal 21.
Ground is supplied
●
to BCM (body control module) terminals 49 and 52
●
through grounds M14 and M78
●
to unified meter and A/C amp. terminals 29 and 30
●
through grounds M14 and M78
●
to combination meter terminals 22, 23 and 24
●
through grounds M14 and M78.
When the remote control entry system is triggered by input from the key fob, the BCM supplies power
●
through BCM terminal 45
●
to front combination lamp LH terminal 2
●
to rear combination lamp LH terminal 3
●
through BCM terminal 46
●
to front combination lamp RH terminal 2
●
to rear combination lamp RH terminal 3.
Ground is supplied
●
to the front combination lamp LH terminal 8 through grounds E13, E26 and E28
●
to the front combination lamp RH terminal 8 through grounds E13, E26 and E28
●
to the rear combination lamp LH terminal 4 through grounds B7 and B20
●
to the rear combination lamp RH terminal 4 through grounds B7 and B20.
The BCM also supplies input to unified meter and A/C amp. terminals 1 and 11 across the CAN communica-
tion lines.
The unified meter and A/C amp. which received the turn indicator signal makes a left and right turn signal indi-
cator turn on in combination meter.
With power and input supplied, the BCM controls the flashing of the hazard warning lamps when key fob is
used to activate the remote control entry system.

CAN Communication System Description
AKS004KC
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
