OUTLINE
Electric sunroof system consists of

Front door switches

Sunroof switch

Sunroof motor assembly

BCM (body control module)
BCM supplies power to the sunroof motor. Sunroof operation depends on sunroof switch condition.
OPERATION
Power is supplied at all times

through 50A fusible link (letter f , located in the fuse and fusible link box)

to BCM terminal 70, and

through BCM terminal 69

tor E46 terminal 5 (R), transfer shift low relay harness connector
E47 terminal 5 (R) and ground.
4. Turn ignition switch “ON”. (Do not start engine.)
5. Check voltage between transfer shift high relay harness connec-
tor E46 terminal 5 (R), transfer shift low relay harness connector
E47 terminal 5 (R) and ground.
OK or NG
OK >> GO TO 4.
NG >> Check the following. If any items are damaged, repair or
replace damaged parts.

20A fuse No. 57 located in the fuse and relay box. Refer to PG-4, "POWER SUPPLY ROUTING
CIRCUIT" .

Harness for short or open between battery, transfer shift high relay harness connector E46 ter-
minal 5 (R) and transfer shift low relay harness connector E47 terminal 5 (R). Continuity should exist.

FRONT WIPER AND WASHER SYSTEM
Revision: October 20052005 QX56
FRONT WIPER AND WASHER SYSTEMPFP:28810
Components Parts and Harness Connector LocationEKS00BDS
System DescriptionEKS00BDT

Both front wiper relays are located in the IPDM E/R (intelligent power distribution module engine room).

The wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input ter-
minals. Terminal combination status is read by the BCM when the wiper switch is turned ON.

BCM controls front wiper LO, HI, and INT (intermittent) operation.

IPDM E/R (intelligent power distribution module engine room) operates the wiper motor according to CAN
communication signals from the BCM.
Power is supplied at all times

through 50A fusible link (letter f , located in the fuse and fusible link box)

to BCM terminal 70, and

through 30A fuse (No. 39, located in the IPDM E/R)

to front wiper relay (located in the IPDM E/R).
With the ignition switch in ON or START position, power is supplied

through 10A fuse (No. 9, located in the fuse block J/B)
