[54B] SMART WIRING SYSTEM (SWS) NOT 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. Pulse check Check the input signals below which are related to the vehicle speed-dependent intermittent wiper.
System switch | Check conditions
--- | ---
Ignition switch (ACC) | When turned from LOCK (OFF) position to the ACC position
Vehicle speed signal (engine-A/T-ECU) | When the vehicle speed has reached 10 km/h or more
OK: The MUT-II/III sounds or the voltmeter needle fluctuates. Q: Are the check result normal? All the signals are received normally.: Go to Step 3. The ignition switch (IG1) signal is not received.: Refer to inspection procedure P-1 "The ignition switch (ACC) signal is not received ." The vehicle speed signal (engine-A/T-ECU) is not received.: Refer to inspection procedure P-15 "The vehicle speed signal is not received ."
| Step 3. Check the SWS monitor customized function. Use the SWS monitor customize function to confirm that "SPEED SEN WIP" is set to "W.FUNCTION". CAUTION The SWS monitor must be used in order to confirm and change that setting. Use the SWS monitor to confirm and/or change the customized function. Q: Is the check result normal? YES: Go to Step 4. NO: Use the SWS monitor customize function to set the "SPEED SEN WIP" to "W.FUNCTION" (Refer to GROUP 54C - Adjustment function ).
| 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.
