[54D] SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR <Except for 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. <Except vehicles for GCC> | PRINT PAGE / INDEX / PRIOR / NEXT

INSPECTION PROCEDURE G-6: The intermittent wiper interval is not changed according to the vehicle speed. <Except vehicles for GCC>
| 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. Check the adjustment function. Check that the interior lamp automatic shutdown function has been enabled by using the adjustment function. Q: Is the check result normal? YES: Go to Step 2. NO: Enable the interior lamp automatic shutdown function by using the adjustment function. Refer to .
| Step 2. 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 3. NO: Refer to Inspection Procedure G-5 "The intermittent wiper interval can not be adjusted by operating the windshield intermittent wiper volume control ."
| Step 3. Pulse check Check the input signals below which are related to the vehicle speed-dependent intermittent wiper.
System switch | Check condition
--- | ---
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: Is the check result normal? All the signals are received normally.: Go to Step 4. 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-14 "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.
