Self-DiagnosisEES002F1
DESCRIPTION
During driving, the low tire pressure warning system receives the signal transmitted from the transmitter
installed in each wheel, and turns on the low tire pressure warning lamp when the tire pressure becomes low.
The control unit (BCM) for this system has pressure judgement and self-diagnosis functions.
FUNCTION
When the low tire pressure warning system detects low inflation pressure or an internal malfunction, the low
tire pressure warning lamp in the combination meter comes on. The malfunction location is indicated by the
low tire pressure warning lamp flashing and the buzzer sounding.

FRONT WIPER AND WASHER SYSTEM

FRONT WIPER AND WASHER SYSTEMPFP:28810
Components Parts and Harness Connector LocationEKS00I1G
System DescriptionEKS00I1H

Front wiper relays (front wiper relay, front wiper high relay) are located in the IPDM E/R (intelligent power
distribution module engine room).

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.
OUTLINE
Power is supplied at all times

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

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

to BCM terminal 70,

through 30A fuse (No. 39, located in IPDM E/R)

to front wiper relay located in IPDM E/R

through 15A fuse (No. 52, located in IPDM E/R), and

through 20A fuse (No. 53, located in IPDM E/R)

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

through ignition relay (located in IPDM E/R)

6. CHECK IPDM E/R
With CONSULT-ll
1. Connect IPDM E/R connector E45.
2. Turn ignition switch ON.
3. Select “IPDM E/R” by CONSULT-II, and select “ACTIVE TEST” on “SELECT DIAG MODE” screen.
4. Select “FRONT WIPER” on “SELECT TEST ITEM” screen.
5. Touch “LO” or “HI” screen.
6. Check voltage between IPDM E/R connector E45 terminals 32
and 33 and ground while front wiper (HI, LO) is operating.
Without CONSULT-ll
1. Connect IPDM E/R connector E45.
2. Turn ignition switch ON.
3. Start auto active test. Refer to PG-21, "
Auto Active Test" .
4. Check voltage between IPDM E/R connector E45 terminals 32 and 33 and ground while front wiper (HI,
LO) is operating.
OK or NG
OK >> Replace front wiper motor. Refer to WW-25, "Removal and Installation of Front Wiper Drive
Assembly" .
NG >> Replace IPDM E/R. Refer to PG-29, "
Removal and Installation of IPDM E/R" .
Front Wiper Does Not Return to Stop Position (After Front Wiper Operate for 10
Seconds, They Stop for 20 Seconds, and After Repeating the Operations Five
Times, They Become Inoperative)
EKS00I1U
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 PROT” item
shows “BLOCK”.
