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.

COMBINATION SWITCH READING FUNCTION
Description

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

BCM reads information of a maximum of 20 switches by combining five output terminals (OUTPUT 1-5)
and five 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.
BCM - Operation Table of Combination Switches

BCM reads operation status of combination switch using combinations shown in table below.

Wiper Dial Position Setting
Front wiper intermittent operation delay interval is determined from a combination of 3 switches (intermittent
operation dial position 1, 2, and 3) and vehicle speed signal.
After each intermittent operation delay interval, BCM sends front wiper request signal to IPDM E/R.
Example: For wiper dial position 1
Using combination switch reading function, BCM detects ON/OFF status of intermittent operation dial posi-
tions 1, 2, and 3.
When combination switch status is as listed below, BCM determines that it is wiper dial position 1.

Intermittent operation dial position 1: ON (Continuity exists between combination switch output 3 and input
1.)

Intermittent operation dial position 2: ON (Continuity exists between combination switch output 5 and input
1.)

Intermittent operation dial position 3: ON (Continuity exists between combination switch output 4 and input
2.)
BCM determines front wiper intermittent operation delay interval from wiper dial position and vehicle speed,
and sends wiper request signal (INT) to IPDM E/R.
CAN Communication System DescriptionNKS003WD
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-board multi-
plex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

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.
