STEP 1. Use the scan tool MB991958 to check if an 
ETACS-related diagnostic trouble code is set. 
Connect the scan tool. Refer to GROUP 54A ETACS, "Diag-
nostic function 

P.54A-729

."

Q: Is the diagnostic trouble code set?

YES : Diagnose the ETACS-ECU. Refer to GROUP 54A 

ETACS, "Diagnostic trouble code chart 

P.54A-732

."

NO :  Go to Step 2.

STEP 2. Check the input signal related to the rear wiper 
operation.

• Ignition switch: ACC

OK: Normal condition is displayed.

Q: Is the check result normal?

NO :  Go to Step 3.
YES : Refer to GROUP 54A 

− ETACS, Input signal 

procedures 

P.54A-785

.

STEP 3. Check the rear wiper motor connector F-04 for 
loose, corroded or damaged terminals, or terminals 
pushed back in the connector.
Q: Is rear wiper motor connector F-04 in good condition?

YES : Go to Step 4.
NO :  Repair or replace the damaged component(s). Refer

STEP 4. Check the rear wiper motor.
(1) Disconnect rear wiper motor connector F-04.
(2) Connect a battery to the wiper motor as shown in the 

illustration and inspect the motor operation.

Q: Is the rear wiper motor in good condition?

YES : Go to Step 5.
NO :  Replace the rear wiper motor. Verify that the rear 

wiper works normally.

STEP 5. Check the ground circuit to the rear wiper motor. 
Measure the resistance at the rear wiper motor connector 
F-04.
(1) Disconnect rear wiper motor connector F-04 and measure 

the resistance available at the wiring harness side of the 
connector.

(2) Measure the resistance value between terminal 3 and 

ground.

• The resistance should be 2 Ω or less.

Q: Is the measured resistance 2 

Ω or less?

YES : Go to Step 7.
NO :  Go to Step 6.

STEP 6. Check the wiring harness between rear wiper 
motor connector F-04 (terminal 3) and ground.
Q: Is the wiring harness between rear wiper motor 

connector F-04 (terminal 3) and ground in good 
condition?
YES : No action is necessary and testing is complete.
NO :  The wiring harness may be damaged or the 

connector(s) may have loose, corroded or damaged 
terminals, or terminals pushed back in the connector. 
Repair the wiring harness as necessary. Verify that

STEP 7. Check ETACS-ECU connector C-311 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Is ETACS-ECU connector C-311 in good condition?

YES : Go to Step 8.
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.

STEP 8. Check the wiring harness between rear wiper 
motor connector F-04 (terminal 1) and ETACS-ECU 
connector C-311 (terminal 5).
NOTE: Also check junction block connector D-12 for loose, cor-
roded or damaged terminals, or terminals pushed back in the 
connector. Repair or replace the damaged component(s) as 
described in GROUP 00E, Harness Connector Inspection 

P.00E-2

.

Q: Is the wiring harness between rear wiper motor 

connector F-04 (terminal 1) and ETACS-ECU connector 
C-311 (terminal 5) in good condition?
YES : Replace the ETACS-ECU. Verify that the rear wiper 

works normally.

NO :  The wiring harness may be damaged or the 

connector(s) 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.
