Transmitter Function Code ErrorNES000KD
MALFUNCTION CODE NO. 41, 42, 43, 44
1. ID REGISTRATION (CORRECTION OF TRANSMITTER LOCATION)
1. Perform ID registration of all transmitters.
2. Drive at a speed of 40 km/h (25 MPH) or more for 3 minutes, and then drive the vehicle at any speed for
10 minutes.
>> GO TO 2.
2. REPLACE TIRE PRESSURE TRANSMITTER
1. Check low tire pressure warning lamp condition again, and replace malfunctioning tire pressure transmit-
ter.
2. Perform ID registration of all transmitter.
Can ID registration of all tire pressure transmitters be completed?
YES >> GO TO 3.
NO >> GO TO WT-29, "
Transmitter no Data" .
3. VEHICLE DRIVING
Drive at a speed of 40 km/h (25 MPH) or more for 3 minutes, and then drive the vehicle at any speed for 10
minutes. Then check all tire pressures with CONSULT-II “DATA MONITOR” within 5 minutes.
Does
“DATA MONITOR” display tire pressure as normal without any warning lamp?

FRONT WIPER AND WASHER SYSTEM
Revision: 2007 April2007 M35/M45
FRONT WIPER AND WASHER SYSTEMPFP:28810
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)
