INSPECTION PROCEDURE D-5: The power window timer function does not work normally. <Vehicles for Argentina>
| CAUTION Whenever the ECU is replaced, ensure that the input and output signal circuits are normal.
| OPERATION The ETACS-ECU operates this function in accordance with the input signals below. Ignition switch (IG1) Driver's door switch
| COMMENTS ON TROUBLE SYMPTOM If the power window timer function does not work normally, these input signal circuit(s), the power window main switch or the ETACS-ECU may be defective.
| POSSIBLE CAUSES Malfunction of the front door switch (LH) Malfunction of the power window main switch Malfunction of the ETACS-ECU Damaged harness wires and connectors
| DIAGNOSIS PROCEDURE
| Step 1. Check the power supply circuit. When the ignition switch is turned to the LOCK (OFF) position, check if the hazard warning lamps illuminate. Q: Is the check result normal? YES: Go to Step 2. NO: Refer to Inspection Procedure A-2 "Check the ETACS-ECU battery power supply circuit ."
