DIAGNOSTIC PROCEDURE

Step 1. Use the MUT-II/III to confirm a diagnosis 
code.

Check that the ETACS-ECU sets a diagnosis code.

Q: Is diagnosis code set?

YES : 

Refer to diagnosis code chart 

P.54B-17

.

NO : 

Go to Step 2.

Step 2. Pulse check

Check the input signals below which are related to 
the rear wiper.

OK: The MUT-II/III sounds or the voltmeter 
needle fluctuates.

Q: Is the check result normal?

All the signals are received normally. : 

Go to Step 

3.

The ignition switch (ACC) signal is not received. : 

Refer to inspection procedure N-1 "The 
ignition switch (ACC) signal is not received 

P.54B-301

."

The column switch (rear wiper switch) signal is not 
received. : 

Refer to inspection procedure N-6 "The 

column switch (windshield wiper washer 
and rear wiper washer switch) signal is not 
received 

P.54B-320

."

Step 3. Connector check: F-02 rear wiper motor 
connector

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Repair the connector.

Step 4. Check the rear wiper motor.
Refer to GROUP 51 

−

 Rear wiper and washer 

P.51-31

.

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Replace the rear wiper motor.

Step 5. Measure the resistance at the F-02 rear 
wiper motor connector.

(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Resistance between F-02 rear wiper motor 

connector terminal No.1 and body earth

OK: 2 

Ω

 or less

Q: Is the check result normal?

YES : 

Go to Step 7.

NO : 

Go to Step 6.

Step 6. Check the wiring harness between F-02 
rear wiper motor connector terminal No.1 and 
body earth.

•

Check the earth line for open or short circuit.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

−

 How to 

Cope with Intermittent Malfunction 

P.00-6

).

NO : 

Repair the wiring harness.

Step 7. Connector check: C-217 ETACS-ECU 
connector

Q: Is the check result normal?

YES : 

Go to Step 8.

NO : 

Repair the connector.

Step 8. Check the wiring harness between C-217 
ETACS-ECU connector terminal No.16 and F-02 
rear wiper motor connector terminal No.2.
