FRONT WIPER AND WASHER SYSTEM

FRONT WIPER AND WASHER SYSTEMPFP:28810
Components Parts and Harness Connector LocationBKS001TF
System DescriptionBKS001TG

BCM (Body Control Module) controls front wiper low, high and intermittent operation.

IPDM E/R (Intelligent Power Distribution Module Engine Room) operates front wiper motor according to
CAN communication signals from BCM.
Power is supplied at all times

to ignition relay (located in IPDM E/R), from battery direct,

through 50 A fusible link (letter M, located in fuse and fusible link block)

to BCM terminal 55,

through 15 A fuse [No. 17, located in fuse block (J/B)]

to BCM terminal 42,

through 20 A fuse (No. 73, located in IPDM E/R)

to front wiper relay (located in IPDM E/R),

through 15 A fuse (No. 78, located in IPDM E/R)

to CPU (central processing unit) located in IPDM E/R,

through 15 A fuse (No. 71, located in IPDM E/R)

to CPU located in IPDM E/R.
When the ignition switch ON or START position, power is supplied

to ignition relay (located in IPDM E/R),

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

to BCM terminal 38,

MIST OPERATION
When the front wiper switch is turned to the MIST position, front wiper low speed operation cycles once and
then stops.
For additional information about front wiper operation under this condition. Refer to WW-5, "
LOW SPEED
WIPER OPERATION" .
If the switch is held in the MIST position, low speed operation continues.
FAIL-SAFE FUNCTION
If an abnormality occurs in CAN communications, IPDM E/R holds the condition just before fail-safe status is
initiated until ignition switch is turned off. (If front wipers were operating in LO just before the initiation of fail-
safe status, they continue to operate in LO until ignition switch is turned OFF.)
COMBINATION SWITCH READING FUNCTION
Description

BCM reads combination switch (wiper switch) status, and controls front wipers according to the results.

BCM reads information of a maximum of 20 switches by combining 5 output terminals (OUTPUT 1-5) and
5 input terminals (INPUT 1-5).
Operation Description

BCM activates transistors of output terminals (OUTPUT 1-5) periodically and allows current to flow in turn.

If any (one or more) switches are turned ON, circuit of output terminals (OUTPUT 1-5) and input terminals
(INPUT 1-5) becomes active.

At this time, transistors of output terminals (OUTPUT 1-5) are activated to allow current to flow. When volt-
age of input terminals (INPUT 1-5) corresponding to that switch changes, interface in BCM detects volt-
age change, and BCM determines that the switch is ON.

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 position to 4 except when checking waveform or voltage of wiper inter-
mittent dial position. Wiper intermittent dial position can be confirmed on CONSULT-II. Refer to
