to BCM terminal 42.
With ignition switch in ON or START position, power is supplied

to CPU located in IPDM E/R,

through 10A fuse [No.1, located in fuse block (J/B)]

to BCM terminal 38.
With ignition switch in ACC or ON position, power is supplied

through 10A fuse [No. 6, located in fuse block (J/B)]

to BCM terminal 11.
Ground is supplied

to BCM terminal 52

through grounds M30 and M66,

to IPDM E/R terminals 38 and 60

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).
OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position, the BCM receives input signal requesting the parking,
license plate, side marker and tail lamps to illuminate. This input is communicated to the IPDM E/R through
the CAN communication lines. The CPU located in the IPDM E/R controls the tail lamp relay coil and daytime
light relay
* coil. These relay, when energized, directs power to parking, license plate, side marker and tail
lamps, which when energized, directs power

through IPDM E/R terminal 22 (USA models)

through daytime light relay terminal 5 (Canada models)

to front combination lamp LH terminals 6

to front combination lamp RH terminals 6

to rear combination lamp LH terminals 2

to rear combination lamp RH terminals 2

to license plate lamp LH terminal 2, and

to license plate lamp RH terminal 2.
Ground is supplied at all times

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 terminals 3

to rear combination lamp RH terminals 3

to license plate lamp LH terminal 1, and

to license plate lamp RH terminal 1

through grounds B5, B6, D105 and T14 (Coupe models)

through grounds B5, B6 and T14 (Roadster models).
With power and ground supplied, parking, license plate side marker and tail lamps illuminate.
NOTE:
Daytime light relay*: Canada models
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON), and the ignition switch is turned
from ON or ACC to OFF, the battery saver control function is activated.
Under this condition, the parking, license, side marker and tail lamps remain illuminated for 5 minutes, then the
headlamps are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-III.

CAUTION:

Check combination switch system terminal waveform under the loaded condition with lighting
switch, turn signal switch and wiper switch OFF not to be fluctuated by overloaded.

Turn wiper dial position to 4 except when checking waveform or voltage of wiper dial position.
Wiper dial position can be confirmed on CONSULT-III. Refer to LT- 9 1 , "
