The trouble can be an intermittent
malfunction (Refer to GROUP 00
− How to
Cope with Intermittent Malfunction
NO :
Repair the wiring harness.

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
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
