System DescriptionEKS00P93
When front map lamp and room lamp switch is in DOOR position, front map lamp and room lamp ON/OFF is
controlled by timer according to signals from switches including key switch, front door switch (driver side), rear
door switch (driver side)No.1*, rear door switch (driver side)No.2*, unlock signal from keyfob, ignition switch.
When front map lamp and room lamp turns ON, there is a gradual brightening over 1 second. When front map
lamp and room lamp turns OFF, there is a gradual dimming over 1 second.
Front map lamp and room lamp timer is controlled by the BCM (body control module).
Front map lamp and room lamp timer control settings can be changed with CONSULT-II.

1.FUSE INSPECTION
Check the following.
l50A fusible link (letterG, located in the fuse and fusible link box)
l10A fuse [No. 1, located in the fuse block (J/B)]
l10A fuse [No.21 located in the fuse block (J/B)]
NOTE:
Refer toRF-10, "
Component Parts and Harness Connector Location".
OK or NG
OK >> GO TO 2.
NG >> If fuse is blown, be sure to eliminate cause of malfunction before installing new fuse, refer toPG-
4, "POWER SUPPLY ROUTING CIRCUIT".
2.CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connector.
3. Check voltage between BCM and ground.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace BCM power supply circuit.

FRONT WIPER AND WASHER SYSTEM
FRONT WIPER AND WASHER SYSTEM
PFP:28810
Components Parts and Harness Connector LocationEKS00P4U
System DescriptionEKS00P4V
lAll front wiper relays (MAIN, LOW/HIGH) are located in IPDM E/R (intelligent power distribution module
engine room).
lWiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input termi-
nals. Terminal combination status is read by BCM (body control module) when the wiper switch is turned
ON.
lBCM controls front wiper LO, HI, and INT (intermittent) operation.
lIPDM E/R operates the wiper motor according to CAN communication signals from the BCM.
Power is supplied at all times
lto ignition relay (located in IPDM E/R), from battery directly,
lthrough 50A fusible link (letter G, located in fuse and fusible link box)
lto BCM terminal 57,
lthrough 30A fuse (No. 39, located in IPDM E/R)
lto front wiper main relay (located in IPDM E/R).
