STEP 2. Check the input signal by using "FUNCTION
DIAG." menu of the SWS monitor.
Check the input signals from the following switches:

• Ignition switch: ACC

• Rear wiper switch: INT

Operate scan tool MB991502 according to the procedure below
to display "REAR WIPER."

1. Select "SWS."
2. Select "SYSTEM SELECT."
3. Select "SWS MONITOR."
4. Select "FUNCTION DIAG."
5. Select "REAR WIPER."

Check that normal conditions are displayed on the items
described in the table below.

Q: Are normal conditions displayed for "REAR WIPER SW"

and "IG SW (ACC)"?
YES : Go to Step 3.
NO :

• Normal condition is not displayed on the "REAR

WIPER SW": Refer to Inspection Procedure O-7
"ETACS-ECU does not receive a signal from the
rear wiper switch

."

• Normal condition is not displayed on the "IG SW

(ACC)": Refer to Inspection Procedure O-1
"ETACS-ECU does not receive a signal from the

STEP 3. Check the battery power supply circuit to the rear
wiper motor. Test at rear wiper motor connector I-07.
(1) Disconnect rear wiper motor connector I-07 and measure

the voltage available at the harness side of the connector.

(2) Turn the rear wiper switch to the "ON" position.

(3) Measure the voltage between terminal 2 and ground.

• The voltage should be approximately 12 volts (battery

positive voltage).

Q: Is the measured voltage approximately 12 volts (battery

positive voltage)?
YES : Go to Step 7.
NO : Go to Step 4.

STEP 4. Check the rear wiper motor connector I-07 and
ETACS-ECU connector D-222 for loose, corroded or
damaged terminals, or terminals pushed back in the
connector.
Q: Are rear wiper motor connector I-07 and ETACS-ECU

connector D-222 in good condition?
YES : Go to Step 5.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. Verify that the rear wiper works normally.

NOTE: Also check intermediate connectors G-10, D-111 and
junction block connector D-217. If intermediate connectors G-
10, D-111 or junction block connector D-217 are damaged,
repair or replace damaged component(s) as described in
GROUP 00E, Harness Connector Inspection

P.00E-2

.

Q: Are the harness wires between rear wiper motor

connector I-07 (terminal 2) and ETACS-ECU connector
D-222 (terminal 1) in good condition?
YES : Go to step 6.
NO : The wiring harness may be damaged or the

connectors may have loose, corroded or damaged
terminals or terminals pushed back in the connector.
Repair the wiring harness as necessary. Verify that
the rear wiper works normally.
