INSPECTION PROCEDURE H-2: The rear wiper does not stop at the specified park position.
 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 stop normally, the rear wiper motor or the ETACS-ECU may be defective.
POSSIBLE CAUSES
  • Malfunction of the rear wiper motor
  • Malfunction of the ETACS-ECU
  • Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
Step 1. Connector check: F-02 rear wiper motor connector
Q: Is the check result normal?
YES:  Go to Step 2.
NO:  Repair the connector.
Step 2. Check the rear wiper motor.
Refer to GROUP 51 - Rear wiper and washer .
Q: Is the check result normal?
YES:  Go to Step 3.
NO:  Replace the rear wiper motor.
Step 3. Measure the voltage at the F-02 rear wiper motor connector.
  1. Disconnect the connector, and measure at the wiring harness side.
  1. Ignition switch: ACC
  1. Check the voltage between F-02 rear wiper motor connector terminal No. 4 and body earth
    2. OK: Battery positive voltage
Q: Is the check result normal?
YES:  Go to Step 5.
NO:  Go to Step 4.
Step 4. Check the wiring harness between ignition switch (ACC) and F-02 rear wiper motor connector terminal No. 4.
NOTE: Prior to the wiring harness inspection, check intermediate connector F-05 and junction block connectors C-203, C-221 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 ).
NO:  Repair the wiring harness.
Step 5. Connector check: C-217 ETACS-ECU connector
Q: Is the check result normal?
YES:  Go to Step 6.
NO:  Repair the connector.
Step 6. Check the wiring harness between C-217 ETACS-ECU connector terminal No. 17 and F-02 rear wiper motor connector terminal No. 3.
NOTE: Prior to the wiring harness inspection, check intermediate connector F-05 and junction block connector C-221, and repair if necessary.
  • Check the power supply line for open or short circuit.
Q: Is the check result normal?
YES:  Go to Step 7.
NO:  Repair the wiring harness.
Step 7. Check the ETACS SW data by using the SWS monitor.
Check the ETACS-ECU signal, which is related to the rear wiper auto stop function.
  • Ignition switch: ACC or ON
  • When rear wiper is operating
