4, "POWER SUPPLY ROUTING CIRCUIT" .
2. CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connector.
3. Check voltage between BCM harness connector and ground.
OK or NG
OK >> GO TO 3.
NG >> Repair harness or connector.
3. CHECK GROUND CIRCUIT
Check continuity between BCM harness connector and ground.
OK or NG
OK >> INSPECTION END

The BCM then supplies power
through BCM terminal 45
to front combination lamp LH terminal 2
to rear combination lamp LH terminal 2,
through BCM terminal 46
to front combination lamp RH terminal 2
to rear combination lamp RH terminal 2.
Ground is supplied
to front combination lamp LH terminal 8, and
to front combination lamp RH terminal 8
through grounds E17, E43 and B102 (with VDC system, navigation system or telephone)
through grounds E17, E43 and F152 (without VDC system, navigation system and telephone),
to rear combination lamp LH terminal 4, and
to rear combination lamp RH terminal 4
through grounds B5, B6, D105 and T14 (Coupe models)
through grounds B5, B6 and T14 (Roadster models).
The BCM also supplies input to unified meter and A/C amp. terminals 1 and 11 through the CAN communica-
tion lines. This input signal is processed by the unified meter control unit in the combination meter through the
unified meter and A/C amp., which in turn supplies ground to the left and right turn signal indicator lamps.
With the power and ground supplied, BCM controls the flashing of hazard warning lamps.
REMOTE KEYLESS ENTRY SYSTEM OPERATION

COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
CAN Communication System DescriptionNKS004Y5
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.
CAN Communication UnitNKS004Y6
Refer to LAN-48, "CAN System Specification Chart" .
