However, only "OK" is displayed for the ETACS-ECU. When the power windows are closed by means of multimode keyless entry function, "No.C2 PASS DOR AUTO", "No.C6 REAR RH AUTO" and "No.CA REAR LH AUTO" turns from "OFF" to "ON" .
| POSSIBLE CAUSES Malfunction of the ETACS-ECU Malfunction of the power window main switch
| DIAGNOSIS PROCEDURE
| Step 1. Confirm the operation of the power windows. Check that the power windows work normally. Q: Is the check result normal? YES: Go to Step 2. NO: Refer to Inspection Procedure D-1 "Power windows do not work at all ."
| Step 2. ECU check on the SWS monitor Check that the power supply and earth lines to the ETACS-ECU and the power window main switch (power window module) and the SWS communication lines are normal. Ignition switch: OFF Operate the multimode function with the keyless entry transmitter. ECUS TO BE CHECKED ETACS ECU P/W MODULE OK: "OK" are displayed for all the items Q: Is the check result normal? "OK" are displayed for all the items: Go to Step 3. "NG" is displayed on the "ETACS ECU" menu.: Refer to Inspection Procedure A-3 "Communication with the ETACS-ECU is not possible ." "NG" is displayed on the "P/W MODULE" menu.: Refer to Inspection Procedure A-5 "Communication with the power window main switch (power window module) is not possible ."
| Step 3. Function diagnosis by using the SWS monitor Check the SWS communication signal, which are related to the multimode keyless entry system. <Selected item> Keyless entry system - Multi-close Ignition switch: OFF Operate the multimode function with the keyless entry transmitter.
Item No. | Item name | Normal conditions
--- | --- | ---
Item 34 | KEYLESS ENTRY | MULTI CLOSE
OK: Normal condition is displayed. Q: Is the check result normal? YES: Go to Step 4. NO: Replace the ETACS-ECU.
| Step 4. Confirm communication data by using the SWS monitor. Check the SWS communication signal, which are related to the multimode keyless entry system. <Selected item> DOOR CNT.COM. Ignition switch: OFF Operate the multimode function with the keyless entry transmitter.
Item No. | Item name | Normal conditions
--- | --- | ---
Item C2 | PASS DOR AUTO | ON
Item C6 | REAR RH AUTO | ON
Item CA | REAR LH AUTO | ON
OK: Normal conditions displayed for all the items 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 power window main switch.
