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 

P.54Bc-33

."

• 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 
ignition switch (ACC) 

P.54Bc-4

."

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.
