[54D] SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR <Except for Hong Kong spec.> - - SYMPTOM PROCEDURES - WINDSHIELD WIPER AND WASHER - INSPECTION PROCEDURE G-3: The windshield wipers do not stop at the specified park position | PRINT PAGE / INDEX / PRIOR / NEXT

INSPECTION PROCEDURE G-3: The windshield wipers do 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 The windshield wiper motor or the front-ECU may be defective.
| POSSIBLE CAUSES Malfunction of the windshield wiper motor Malfunction of the front-ECU Damaged harness wires and connectors
| DIAGNOSIS PROCEDURE
| Step 1. Connector check: B-07 windshield wiper motor connector Q: Is the check result normal? YES: Go to Step 2. NO: Repair the connector.
| Step 2. Check the windshield wiper motor assembly. Refer to GROUP 51 - Windshield wiper . Q: Is the check result normal? YES: Go to Step 3. NO: Replace the windshield wiper motor assembly.
| Step 3. Measure the voltage at the B-07 windshield wiper motor connector. Disconnect the connector, and measure at the wiring harness side. Ignition switch: ACC Check the voltage between the B-07 windshield wiper motor connector terminal No.2 and body earth. 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 B-07 windshield wiper motor connector terminal No.2 and ignition switch (ACC). NOTE: Prior to the wiring harness inspection, check the junction connectors C-202, C-203 and the intermediate connector C-106 <RH drive vehicles> or C-104 <LH drive vehicles> and repair if necessary. Check the power supply line to ignition switch (ACC) for open 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: A-12X front-ECU connector Q: Is the check result normal? YES: Go to Step 6. NO: Repair the connector.
| Step 6. Check the wiring harness between B-07 windshield wiper motor connector terminal No.1 <RH drive vehicles> or No.3 <LH drive vehicles> and A-12X front-ECU connector terminal No.29. NOTE: Prior to the wiring harness inspection, check the intermediate connector A-14 and repair if necessary. Check the input signal lines. Q: Is the check result normal? YES: Go to Step 7. NO: Repair the wiring harness.
| Step 7. Retest the system. Check that the windshield wipers stop at the specified park position. 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 front-ECU.
