REMOVAL
1. Switch 4WD shift switch to 2WD and set transfer assembly to 2WD.
CAUTION:
When removal transfer control unit, transfer state must be at 2WD or AUTO.
2. Turn the ignition switch OFF and disconnect the battery cables.
3. Remove the lower instrument panel LH (LHD models) or lower instrument panel RH (RHD models). Refer
toIP-13, "
LOWER INSTRUMENT PANEL LH"(LHD models) orIP-13, "LOWER INSTRUMENT PANEL
LH"(RHD models).
4. Disconnect the two transfer control unit connectors.
5. Remove the transfer control unit bolts.
6. Remove the transfer control unit.
INSTALLATION
Installation is in the reverse order of removal.
lWhen installing the transfer control unit, tighten bolts to the specified torque.
CAUTION:
Do not connect harness connector to transfer control unit when 4WD shift switch is at 4LO.
lAfter the installation, check 4WD shift indicator pattern. If NG, adjust position between transfer assembly

Components Parts and Harness Connector LocationEKS00P4U
System DescriptionEKS00P4V
lAll front wiper relays (MAIN, LOW/HIGH) are located in IPDM E/R (intelligent power distribution module
engine room).
lWiper 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 the wiper switch is turned
ON.
lBCM controls front wiper LO, HI, and INT (intermittent) operation.
lIPDM E/R operates the wiper motor according to CAN communication signals from the BCM.
Power is supplied at all times
lto ignition relay (located in IPDM E/R), from battery directly,
lthrough 50A fusible link (letter G, located in fuse and fusible link box)
lto BCM terminal 57,
lthrough 30A fuse (No. 39, located in IPDM E/R)
lto front wiper main relay (located in IPDM E/R).

Front Wiper Does Not Return to Stop Position (After Front Wiper for 10 Sec-
onds, They Stop for 20 seconds, and After Repeating the Operations Five
Times, They Become Inoperative)
EKS00P57
CAUTION:
lWhen auto stop signal has not varied for 10 seconds or longer while IPDM E/R is operating front
wipers, IPDM E/R considers front wipers are locked, and stops wiper output. That causes this
symptom.
lThis status can be checked by “DATA MONITOR” of “IPDM E/R” on which “WIPER PROTECTION”
ITEMS SHOWS “BLOCK”.
1.CHECK FRONT WIPER STOP SIGNAL
With CONSULT-ll
1. Select “BCM” on CONSULT-II. Select “WIPER” on “SELECT
TEST ITEM” screen.
2. Select “DATA MONITOR” on “SELECT DIAG MODE” screen.
Make sure that “WIP AUTO STOP” turns “ACT P” - “STOP P”
linked with wiper operation.
Without CONSULT-ll
GO TO 2.
Does the front wiper operate normally?
YES >> Replace IPDM E/R. Refer toPG-26, "Removal and
Installation of IPDM E/R".
NO >> GO TO 2.
2.CHECK IPDM E/R
Check voltage between IPDM E/R harness connector and ground
while front wiper motor is stopped and while it is operating.
OK or NG
OK >> Replace IPDM E/R. Refer toPG-26, "Removal and
Installation of IPDM E/R".
NG >> GO TO 3.
