Concept of Auto Active Test
IPDM E/R actuates auto active test mode when it receives door switch signal from BCM via CAN commu-
nication line. Therefore, when auto active test mode is activated successfully, CAN communication
between IPDM E/R and BCM is normal.
If any of systems controlled by IPDM E/R cannot be operated, possible cause can be easily diagnosed
using auto active test.

System DescriptionBKS002CC
BCM (Body Control Module) controls headlamp washer operation.
IPDM E/R (Intelligent Power Distribution Module Engine Room) operates headlamp washer pump accord-
ing to CAN communication signal from BCM.
OUTLINE
Power is supplied at all times
to ignition relay (located in IPDM E/R), from battery direct,
through 15A fuse (No. 71, located in IPDM E/R)
to CPU (central processing unit) in IPDM E/R,
through 15A fuse (No. 78, located in IPDM E/R)
to CPU in IPDM E/R,
through 50A fusible link (letter M, located in fuse and fusible link block)
to BCM terminal 55,
through 30A fusible link (letter J, located in fuse and fusible link block)
to headlamp washer relay terminals 1 and 3.
With the ignition switch in the ON or START position, power is supplied
to ignition relay (located in IPDM E/R),
through 10A fuse [No. 1, located in fuse block (J/B)]
to BCM terminal 38.
With the 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 M71 and M72,
to IPDM E/R terminals 38 and 60
through grounds E1 and E31.

When the headlamp washer switch is ON, ground is supplied

through headlamp washer switch terminal 1
through headlamp washer switch terminal 2
through grounds M71 and M72.
HEADLAMP WASHER OPERATION
When the headlamp washer switch is in ON position with the ignition switch in ON position and the lighting
switch in 2ND position, BCM detects the headlamp washer switch ON signal. It also detects the HEAD LAMP1
and 2 (ON) by BCM combination switch reading function. BCM judges that the condition of headlamp washer
operation meets. And then, BCM sends headlamp washer request signal (ON) through CAN communication.
When receiving headlamp washer request signal (ON), IPDM E/R turns ON headlamp washer relay. And then,
headlamp washer pump operates.
Power is supplied
through headlamp washer relay terminal 2
to IPDM E/R terminal 58,
through headlamp washer relay terminal 5
to headlamp washer pump terminal 1.
Ground is supplied
to headlamp washer pump terminal 2
through grounds E1 and E31.
With power and ground supplied, headlamp washer operates.
INTERLOCKED OPERATION WITH FRONT WINDOW WASHER
When the front window washer switch is in ON position at the every first time of ignition switch ON, with the
ignition switch in ON position and the lighting switch in 2ND position, BCM detects the FR WASHER (ON) and
the HEAD LAMP 1 and 2 (ON) by BCM combination switch reading function. BCM judges that the condition of
headlamp washer operation meets. And then, BCM sends headlamp washer request signal (ON) through
CAN communication.
When receiving headlamp washer request signal (ON), IPDM E/R turns ON headlamp washer relay. And then,
headlamp washer pump operates.
