[54C] SMART WIRING SYSTEM (SWS) USING SWS MONITOR <Hong Kong spec.> - - SYMPTOM PROCEDURES - WINDSHIELD WIPER AND WASHER - INSPECTION PROCEDURE G-6: The intermittent wiper interval is not changed according to the vehicle speed. | PRINT PAGE / INDEX / PRIOR / NEXT

INSPECTION PROCEDURE G-6: The intermittent wiper interval is not changed according to the vehicle speed.
| CAUTION Whenever the ECU is replaced, ensure that the input and output signal circuits are normal.
| COMMENTS ON TROUBLE SYMPTOM The ETACS-ECU calculates the intermittent wiper interval according to the vehicle speed signal which is sent by the engine-A/T-ECU. If the intermittent wiper interval does not depend on the vehicle speed, the input circuit of the vehicle speed signal and the ETACS-ECU may be defective.
| POSSIBLE CAUSES Malfunction of the vehicle speed signal (engine-A/T-ECU) Malfunction of the ETACS-ECU Damaged harness wires and connectors
| DIAGNOSIS PROCEDURE
| Step 1. Retest the system. Check that the windshield intermittent wiper interval can be adjusted by operating the windshield intermittent wiper volume control. Q: Is the check result normal? YES: Go to Step 2. NO: Refer to Inspection Procedure G-5 "The intermittent wiper interval can not be adjusted by operating the windshield intermittent wiper volume control ."
| Step 2. Check the adjustment function. Check that "SPEED SEN WIP" is set to "W.FUNCTION" by using the adjustment function. Q: Is the check result normal? YES: Go to Step 3. NO: Set "SPEED SEN WIP" to "W.FUNCTION" by using the adjustment function.(Refer to ).
| Step 3. Check the ETACS ANAL data by using the SWS monitor. Enter a simulated vehicle speed.
Item No. | Item name | Normal conditions
--- | --- | ---
Item 03 | SPEED SENSOR | Displays the speed which fluctuates within ± 2 km/h from the entered vehicle speed.
OK: Normal condition is displayed. Q: Is the check result normal? YES: Go to Step 4. NO: Refer to Inspection Procedure P-15 "The vehicle speed signal is not received."
| Step 4. Retest the system. Check that the intermittent wiper interval depends on the vehicle speed. 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.
