Prior to the wiring harness inspection, check 
intermediate connector G-14 and junction block 
connectors C-202, C-210, and repair if necessary.

• Check the power supply 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.00-5

).

NO : 

Repair the wiring harness.

Step 5. Connector check: C-219 ETACS-ECU 
connector.

Q: Is the check result normal?

YES : 

Go to Step 6.

NO : 

Repair the connector.

Step 7. ETACS switch data by using the SWS 
monitor.

• Ignition switch: ACC or ON

• Operate the rear wiper

NOTE: Confirm that the MUT-III displays from "ON" 
to "OFF" when rear wiper stops at the predetermined 
park position.

OK: Normal conditions is displayed for all 
the items.

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.00-5

).

NO : 

Replace the ETACS-ECU.

Inspection Procedure H-3: When the selector lever is moved to "R" position during the rear wiper 
operation, the rear wiper does not operate at the continuous mode. <A/T>

CAUTION

Whenever the ECU is replaced, ensure that the 
input and output signal circuits are normal.

COMMENTS ON TROUBLE SYMPTOM

If the rear wiper does not operate consecutively 
when the selector lever is moved to the R position 
during the rear wiper operation, the shift position 
input signal circuit or the ETACS-ECU may be 
defective.

POSSIBLE CAUSES

• Malfunction of the engine-A/T-ECU

• Malfunction of the ETACS-ECU

• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

Step 1. Check the operation of the rear wiper.

Check that the rear wiper system should work 
normally by operating the rear wiper switch.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Refer to Inspection Procedure H-1 "Rear 
wiper does not work at all 

P.54C-228

."
