[54D] SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR <Except for Hong Kong spec.> - - SYMPTOM PROCEDURES - POWER WINDOWS - INSPECTION PROCEDURE D-1: Power windows do not work at all. <vehicles for Argentina> | PRINT PAGE / INDEX / PRIOR / NEXT

INSPECTION PROCEDURE D-1: Power windows do not work at all. <vehicles for Argentina>
| CAUTION Whenever the ECU is replaced, ensure that the input and output signal circuits are normal.
| COMMENTS ON TROUBLE SYMPTOM If the power windows do not work at all, the power window relay, the power window main switch or the ETACS-ECU may be defective.
| POSSIBLE CAUSES Malfunction of the power window relay Malfunction of the power window main switch Malfunction of the ETACS-ECU Damaged harness wires and connectors
| DIAGNOSIS PROCEDURE
| Step 1. Pulse check Check the input signal from the ignition switch.
System switch | Check condition
--- | ---
Ignition switch (IG1) | When turned from ACC to ON
OK: The MUT-II/III sounds or the voltmeter needle fluctuates. Q: Is the check result normal? YES: Go to Step 2. NO: Refer to Inspection Procedure P-2 "The Ignition switch (IG1) signal is not received. ."
| Step 2. Connector check: C-208 power window relay connector Q: Is the check result normal? YES: Go to Step 3. NO: Repair the connector.
| Step 3. Check the power window relay. Refer to GROUP 42 - Door - On-vehicle Service . Q: Is the check result normal? YES: Go to Step 4. NO: Replace the power window relay.
| Step 4. Connector check: E-05 power window main switch connector Q: Is the check result normal? YES: Go to Step 5. NO: Repair the connector.
| Step 5. Measure the voltage at the E-05 power window main switch connector. Disconnect the connector, and measure at the wiring harness side. Turn the ignition switch to the ON position. Voltage between terminal 6 and body earth OK: Battery positive voltage Q: Is the check result normal? YES: Go to Step 9. NO: Go to Step 6.
| Step 6. Check the wiring harness between C-208 power window relay connector terminal No.4 and E-05 power window main switch connector terminal No.6. NOTE: Prior to the wiring harness inspection, check intermediate connectors C-118, E-12 and junction block connector C-203, and repair if necessary. Check the power supply line for open circuit. 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: Repair the harness wire, and then go to Step 7.
| Step 7. Measure the voltage at C-208 power window relay connector. Disconnect the connector, and measure at the wiring harness side. Turn the ignition switch to the ON position. Voltage between terminal 5 and body earth OK: Battery positive voltage Q: Is the check result normal? YES: Go to Step 9. NO: Go to Step 8.
| Step 8. Check the wiring harness between C-208 power window relay connector terminal No.5 and fusible link (5). NOTE: Prior to the wiring harness inspection, check intermediate connector C-116 and junction block connector C-203, and repair if necessary. Check the power supply line for open circuit. 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: Repair the wiring harness.
| Step 9. Measure the resistance at C-208 power window relay connector. Disconnect the connector, and measure at the wiring harness side. Resistance between terminal 3 and body earth OK: 2Ω or less Q: Is the check result normal? YES: Go to Step 11. NO: Go to Step 10.
| Step 10. Check the wiring harness between C-208 power window relay connector terminal No.3 and body earth. NOTE: Prior to the wiring harness inspection, check junction block connector C-205, and repair if necessary. Check the earth wires for open circuit. 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: Repair the wiring harness.
| Step 11. Connector check: C-217 ETACS-ECU connector Q: Is the check result normal? YES: Go to Step 12. NO: Repair the connector.
| Step 12. Connector check: C-219 ETACS-ECU connector Q: Is the check result normal? YES: Go to Step 13. NO: Repair the connector.
| Step 13. Check the wiring harness between C-219 ETACS-ECU connector terminal No.59 and E-05 power window main switch connector terminal No.4. NOTE: Prior to the wiring harness inspection, check intermediate connectors C-118, E-12 and joint connector C-02, and repair if necessary. Check the communication lines for open circuit. Q: Is the check result normal? YES: Go to Step 14. NO: Repair the wiring harness.
| Step 14. Retest the system. After the power window main switch is replaced, check that all the power windows work. Replace the power window main switch. Check that the all the power windows work. 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.
