[54E] SMART WIRING SYSTEM (SWS) USING SWS MONITOR <Except for Hong Kong spec.> - - SYMPTOM PROCEDURES - REAR WIPER AND WASHER - INSPECTION PROCEDURE H-3: When the selector lever is moved to "R" position during the rear wiper operation, the rear wiper does not operate at the continuous mode. | PRINT PAGE / INDEX / PRIOR / NEXT

INSPECTION PROCEDURE H-3: When the selector lever is moved to "R" position during the rear wiper operation, the rear wiper does not operate at the continuous mode.
| 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 operate consecutively when the selector lever is moved to the R position during the rear wiper operation, the input signal circuit to the inhibitor switch ("R" position) or the ETACS-ECU may be defective.
| POSSIBLE CAUSES Malfunction of the inhibitor switch Malfunction of the ETACS-ECU Damaged harness wires and connectors
| DIAGNOSIS PROCEDURE
| Step 1. Function diagnosis by using the SWS monitor Check the SWS communication signal, which are related to the R (reverse) gear-linked rear wiper operation. <Selected item> REAR WIPER-REV. INTERLOCK Ignition switch: ON Rear wiper switch: ON Shift position: R position
Item No. | Item name | Normal condition
--- | --- | ---
Item 41 | INHIBITOR SW | ON
OK: Normal condition is displayed. Q: Is the check result normal? YES: Go to Step 2. NO: Refer to Inspection Procedure P-3 "The inhibitor switch (reverse position) signal is not received ."
| Step 2. Retest the system. Check that the rear wiper operates consecutively when the selector lever is moved to the R position during the rear wiper operation. 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.
