After Front Wiper Operate for 10 Seconds, They Stop for 20 Seconds, and After
Repeating the Operations Five Times, They Become Inoperative
NKS0052J
CAUTION:

When auto-stop signal has not varied for 10 seconds or longer while IPDM E/R is operating front
wipers, IPDM E/R considers that front wipers are locked, and stops wiper output. That causes this
symptom.

This status can be checked by “DATA MONITOR” of “IPDM E/R” on which “WIPER PROTECTION”
item shows “BLOCK”.
1. CHECK WIPER MOTOR SIGNAL
CONSULT-III DATA MONITOR
1. Select "WIP AUTO STOP" of BCM data monitor item.
2. make sure that “WIP AUTO STOP” turns “ACT P” - “STOP P” linked with wiper operation.

Components Parts and Harness Connector LocationNKS0052X
System DescriptionNKS0052Y

Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input termi-
nals. Terminal combination status is read by BCM when switch is turned ON.

BCM (body control module) controls rear wiper ON and INT (intermittent) operation.
OUT LINE
Power is supplied at all times

through 40 A fusible link (letter F, located in fuse, fusible link and relay box)

to BCM terminal 55,

through 10 A fuse [No. 18, located in fuse block (J/B)]

to BCM terminal 42.
When ignition switch is in ON or START position, power is supplied

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

to BCM terminal 38,

through 10 A fuse (No. 84, located in IPDM E/R)

through IPDM E/R terminal 44

to rear washer pump terminal 2.
Ground is supplied

to BCM terminal 52

through grounds M30 and M66,

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 dial position to 4 except when checking waveform or voltage of wiper dial position.
Wiper dial position can be confirmed on CONSULT-III. Refer to WW-43, "
