| POSSIBLE CAUSES Malfunction of the key reminder switch Malfunction of the driver's door switch Malfunction of the driver's door lock actuator Malfunction of the ETACS-ECU Damaged harness wires and connectors
| DIAGNOSIS PROCEDURE
| Step 1. ECU check by using the SWS monitor Check that the power supply and earth lines to the ETACS-ECU and the SWS communication lines are normal. Ignition switch: OFF ECUS TO BE CHECKED ETACS ECU OK: "OK" is displayed on the "ETACS ECU" menu. Q: Is the check result normal? YES: Go to Step 2. NO: Refer to Inspection Procedure A-3 "Communication with ETACS-ECU is not possible ."
| Step 2. SWS monitor data list Check the SWS communication signals, which are related to the key reminder function. <Selected item> ETACS Driver's door: open
Item No. | Item name | Normal condition
--- | --- | ---
Item 32 | DR DOOR SW*1 | ON
