INSPECTION PROCEDURE D-5: The power window timer function does not work normally. <except 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 Passenger's door switch <vehicles for Australia>
| 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 (RH) 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 ."
| Step 2. Pulse check Check the input signals below, which are related to the power window timer function.
System switch | Check condition
--- | ---
Ignition switch (IG1) | When turned from ACC to ON
Driver's door switch | When the driver's door is opened
Passenger's door switch <vehicles for Australia> | When the Passenger's door is opened
OK: The MUT-II/III sounds or the voltmeter needle fluctuates. Q: Is the check result normal? All the signals are received normally.: Go to Step 3. The ignition switch (IG1) signal is not received.: Refer to Inspection Procedure P-2 "The ignition switch (IG1) signal is not received ." The driver’s door switch signals are not received.: Refer to Inspection Procedure P-4 "The driver's door switch signal is not received <LH drive vehicles>." Refer to Inspection Procedure P-4 "The driver's door switch signal is not received <RH drive vehicles>." The passenger’s door switch signals are not received.: Refer to Inspection Procedure P-20 "The passenger’s door switch signal is not received . <vehicles for Australia>"
| Step 3. Connector check: E-05 power window main switch connector Q: Is the check result normal? YES: Go to Step 4. NO: Repair the connector.
| Step 4. Check the power window main switch. Refer to GROUP 42 - Door . Q: Is the check result normal? YES: Go to Step 5. NO: Replace the power window main switch.
| Step 5. Retest the system. Check that the power window timer function works normally. 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.
