• to rear combination lamp LH terminal 1
• through grounds B7 and B19.
The BCM also sends a request, via the CAN communication lines, to the combination meter to flash the left
turn signal indicator. The unified meter control unit in the combination meter supplies ground to the left turn
signal indicator lamp and activates the audible turn signal indicator.
With power, ground and input supplied, the BCM controls the flashing of the turn signal lamps.
RH Turn Signal Lamp When turn signal switch is moved to the right turn position, the BCM receives an input signal requesting right
turn signals to flash. The BCM then supplies power
• through BCM terminal 61
• to front combination lamp RH terminal 4 and
• to rear combination lamp RH terminal 6.
Ground is supplied
• to front combination lamp RH terminal 5
• through grounds E15 and E24,
• to rear combination lamp RH terminal 1
• through grounds B117, B132 (all models) and D402 (with hatchback).
The BCM also sends a request, via the CAN communicati on lines, to the combination meter to flash the right
turn signal indicator. The unified meter control unit in the combination meter supplies ground to the right turn
signal indicator lamp and activates the audible turn signal indicator.
With power, ground and input supplied, the BCM controls the flashing of the turn signal lamps.
HAZARD LAMP OPERATION Power is supplied at all times
• through 40A fusible link (letter g , located in fuse, fusible link and relay box)
• to BCM terminal 70,
• through 10A fuse [No. 8, located in fuse block (J/B)]
• to BCM terminal 57,
• through 10A fuse [No. 13, located in fuse block (J/B)]
• to combination meter terminal 27.
Ground is supplied
• to hazard switch terminal 1,
• to BCM terminal 67, and
• to combination meter terminals 21, 22 and 23
• through grounds M57 and M61.
When hazard switch is depressed, ground is supplied
• through hazard switch terminal 2
• to BCM terminal 29.
BCM then supplies power
• to front combination lamp LH terminal 4 and
• to rear combination lamp LH terminal 6
• through BCM terminal 60,
• to front combination lamp RH terminal 4 and
• to rear combination lamp RH terminal 6
• through BCM terminal 61.
Ground is supplied
• to front combination lamp LH and RH terminal 5
• through grounds E15 and E24,
• to rear combination lamp LH terminal 1
• through grounds B7 and B19,
• to rear combination lamp RH terminal 1
• through grounds B117, B132 and D402 (hatchback).
The BCM also supplies input to combination meter ac ross the CAN communication lines. This input is pro-
cessed by unified meter control unit in combination mete r, 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 Power is supplied at all times
• through 40A fusible link (letter g , located in fuse, fusible link and relay box)
• to BCM terminal 70,

A sensor-transmitter integrated with a valve is installed in each
wheel, and transmits a detected air pressure signal in the form of a
radio wave. The radio signal is received by the remote keyless entry
receiver.
REMOTE KEYLESS ENTRY RECEIVER The remote keyless entry receiver is shown with the glove box
removed. The remote keyless entry receiver receives the air pres-
sure signal transmitted by the transmitter in each wheel.
COMBINATION METER The combination meter receives tire pressure status from the BCM
using CAN communication. When a low tire pressure condition is
sensed by the BCM, the combination meter low tire pressure warn-
ing lamp is activated.
TIRE PRESSURE WARNING CHECK CONNECTOR The tire pressure warning check connector can be grounded in order to initiate self-diagnosis without a CON-
SULT-III. Refer to WT-17, " Self-Diagnosis (Without CONSULT-III) " . The tire pressure warning check connector
is located behind the lower portion of the instrument panel LH. Refer to PG-38, " Harness Layout " . WEIA0186E
