| DIAGNOSIS PROCEDURE
| Step 1. Check the adjustment function. Q: Is "KEY-OFF TMR T" set to "30s" by using the adjustment function? YES: Go to Step 2. NO: Set "KEY-OFF TMR T" to "30s" by using the adjustment function. (Refer to .)
| 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. Turn the ignition switch from the ON to the OFF position. ECUS TO BE CHECKED ETACS ECU P/W MODULE OK: "OK" are displayed for all the items NOTE: "OK" is displayed for the power window switch (power window module) for approximately one minute, and then changed to "NG".

"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 power window timer function. <Selected item> POWER WINDOW Turn the ignition switch from the ON to the OFF position.
Item No. | Item name | Normal conditions
--- | --- | ---
30 | IG SW IG1 | OFF
33 | P/W SW ACCEPT | PERMIT
71 | P/W ECU ACK | NORMAL ACK
