< SERVICE INFORMATION >
HEADLAMP - XENON TYPE -
 to combination meter terminal 7.
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 terminals 49 and 52
 through grounds M35, M45 and M85,
 to IPDM E/R terminals 38 and 60
 through grounds E21, E50 and E51,
 to combination meter terminals 5, 6 and 15
 through grounds M35, M45 and M85.
HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in the 2ND position, the BCM receives input signal requesting the headlamps to illumi-
nate. This input signal is communicated to the IP DM E/R through the CAN communication lines. The CPU
located in the IPDM E/R controls the headlamp lo w relay coil, which when energized, directs power
 through 15A fuse (No. 76, located in IPDM E/R)
 through IPDM E/R terminal 20
 to front combination lamp RH terminal 6,
 through 15A fuse (No. 86, located in IPDM E/R)
 through IPDM E/R terminal 30
 to front combination lamp LH terminal 6.
Ground is supplied
 to front combination lamp RH and LH terminals 7
 through grounds E21, E50 and E51,
With power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch in the 2ND position and placed in the HIGH or PASS position, the BCM receives input
signal requesting the headlamp high beams to illuminate. Th is input signal is communicated to the IPDM E/R
through the CAN communication lines. The CPU located in the IPDM E/R controls the headlamp high relay
coil and low relay coil, which when energized, directs power
 through 15A fuse (No. 76, located in IPDM E/R)
 through IPDM E/R terminal 20
 to front combination lamp RH terminal 6,
 through 15A fuse (No. 86, located in IPDM E/R)
 through IPDM E/R terminal 30
 to front combination lamp LH terminal 6,
 through 10A fuse (No. 72, located in IPDM E/R)
 through IPDM E/R terminal 27
 to front combination lamp RH terminal 5,
 through 10A fuse (No. 74, located in IPDM E/R)
 through IPDM E/R terminal 28
 to front combination lamp LH terminal 5.
Ground is supplied
 to front combination lamp RH and LH terminals 7
 through grounds E21, E50 and E51,
With power and ground supplied, the high beam headlamps illuminate.
If voltage is applied to a high beam solenoid, the bulb shade will move, even a xenon head lamp bulb comes
out, and a high beam and a low beam are changed.
The unified meter and A/C amp. that received the hi gh beam request signal by BCM through the CAN commu-
nication makes a high beam indicator lamp turn on in combination meter.
COMBINATION SWITCH READING FUNCTION
Refer to BCS-4, "System Description".
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 headlamps remain illumi nated for 5 minutes, then the headlamps are turned OFF.

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 intermittent dial posi tion to 4 except when checking wavef orm or voltage of wiper inter-
mittent dial position. Wiper intermittent dial position can be confirmed on CONSULT-III. Refer to LT-
103, "CONSULT-III Functions (BCM)".
