Components Parts and Harness Connector LocationNKS003WB
System DescriptionNKS003WC

Front wiper relays (HIGH, LOW) are included in IPDM E/R (intelligent power distribution module engine
room).

Front wiper reverse relay is included in relay box-1. Refer to PG-98, "ELECTRICAL UNITS LOCATION" .

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 (body control module) when switch is turned ON.

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

IPDM E/R operates wiper motor according to CAN communication signals from BCM.

Front wiper motor switches LOW speed to/from HIGH speed by BCM function to change polarity.
OUTLINE
Power is supplied at all times

to ignition relay, located in IPDM E/R, from battery directly,

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

to BCM terminal 55,

through 10 A fuse [No. 21, located in fuse block (J/B)]

to BCM terminal 42,

through 30 A fuse (No. 73, located in IPDM E/R)

to front wiper low relay, located in IPDM E/R

to front wiper reverse relay terminal 5,

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

CONSULT-II Functions (IPDM E/R)NKS003WM
CONSULT-II can display each diagnostic item using the diagnostic test mode shown following.
CONSULT-II BASIC OPERATION
Refer to GI-38, "CONSULT-II Start Procedure" .
DATA MONITOR
Operation Procedure
1. Touch “DATA MONITOR” on “SELECT DIAG MODE ” screen.
2. Touch “ALL SIGNALS”, “MAIN SIGNALS” or “SELECTION FROM MENU” on the “SELECT MONITOR
ITEM” screen.
3. When “SELECTION FROM MENU” is selected, touch individual items to be monitored. In “ALL SIG-
NALS”, all items are monitored. In “MAIN SIGNALS”, predetermined items are monitored.
4. Touch “START”.
5. Touch “RECORD” while monitoring to record the status of the item being monitored. To stop recording,
touch “STOP”.
All Signals, Main Signals, Selection From Menu
NOTE:
Perform monitoring of IPDM E/R data with the ignition switch ON. When the ignition switch is at ACC, the dis-
play may not be correct.
ACTIVE TEST
Operation Procedure
1. Touch “ACTIVE TEST” on “SELECT DIAG MODE” screen.
2. Touch “FRONT WIPER” on “SELECT TEST ITEM” screen.
3. Touch item to be tested, and check operation.
4. Touch “OFF” while testing to stop the operation.
Diagnosis Mode Description
SELF−DIAG RESULTS Refer to PG-20, "
SELF-DIAG RESULTS" .
DATA MONITOR The input/output data of IPDM E/R is displayed in real time.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication can be read.
ACTIVE TEST IPDM E/R sends a drive signal to electronic components to check their operation.
ALL SIGNALS Monitors all items.
MAIN SIGNALS Monitor the predetermined item.
SELECTION FROM MENU Selects items and monitors them.
