[54B] SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR <Hong Kong spec.> - - INPUT SIGNAL PROCEDURES - INSPECTION PROCEDURE P-9: When the sunroof switch is operated, the switch signals are not received. | PRINT PAGE / INDEX / PRIOR / NEXT

INSPECTION PROCEDURE P-9: When the sunroof switch is operated, the switch signals are not received.
| CAUTION Whenever the ECU is replaced, ensure that the input signal circuit is normal.
| COMMENTS ON TROUBLE SYMPTOM If the input signal from the sunroof switch is abnormal, the sunroof input check response signal will not be sent to the SWS communication line.
| POSSIBLE CAUSES Malfunction of the sunroof assembly Malfunction of the sunroof switch Damaged harness wires and connectors
| DIAGNOSIS PROCEDURE
| Step 1. Check the operation condition of the sunroof. Check that the sunroof works normally. Q: Is the check result normal? YES: Go to Step 2. NO: Refer to Inspection Procedure F-1 "The sunroof does not work at all" .
| Step 2. Connector check: D-06 sunroof switch connector Q: Is the check result normal? YES: Go to Step 3. NO: Repair the connector.
| Step 3. Check the sunroof switch. Refer to GROUP 42 - Sunroof . Q: Is the check result normal? YES: Go to Step 4. NO: Replace the sunroof switch.
| Step 4. Measure the resistance at the D-06 sunroof switch connector. Disconnect the connector, and measure at the wiring harness side. Continuity between D-06 sunroof switch connector terminal No.4 and body earth OK: 2Ω or less Q: Is the check result normal? YES: Go to Step 6. NO: Go to Step 5.
| Step 5. Check the wiring harness between D-06 sunroof motor switch connector terminal No.4 and body earth. NOTE: Prior to the wiring harness inspection, check intermediate connector C-218, 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 6. Connector check: D-09 sunroof motor assembly connector Q: Is the check result normal? YES: Go to Step 7. NO: Repair the connector.
| Step 7. Check the wiring harness from D-09 sunroof motor assembly connector (terminals 6, 7 and 8) to D-06 sunroof switch connector (terminals 6, 3 and 5). Check the input line for open circuit. Q: Is the check result normal? YES: Go to Step 8. NO: Repair the wiring harness.
| Step 8. Connector check: C-219 ETACS-ECU connector Q: Is the check result normal? YES: Go to Step 9. NO: Repair the connector.
| Step 9. Check the wiring harness between D-09 sunroof motor assembly connector terminal No.10 and C-219 ETACS-ECU connector terminal No.59. NOTE: Prior to the wiring harness inspection, check joint connector C-02 and intermediate connector C-218, and repair if necessary. Check the communication lines for open circuit. Q: Is the check result normal? YES: Go to Step 10. NO: Repair the wiring harness.
| Step 10. Retest the system. Check that each switch signal is received by operating the sunroof switch. 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 sunroof motor assembly.
