INSPECTION PROCEDURE 2: Inside/Outside Air Selection is not possible.
COMMENTS ON TROUBLE SYMPTOM If the inside/outside air selection damper motor does not operate normally, the inside/outside air selection damper motor system may be defective.
TROUBLESHOOTING HINTS Malfunction of the inside/outside air selection damper motor Damaged the wiring harness or connectors Malfunction of the manual air conditioner control panel (A/C-ECU)
| DIAGNOSIS
| Step 1. Check the rear window defogger and A/C operations. Q: Do the rear window defogger and A/C work normally? YES: Go to Step 2. NO: Refer to Inspection procedure 9 "Malfunction of the A/C-ECU power supply system ."
| Step 2. Measure the voltage at C-311 outside/inside air selection damper control motor connector. Disconnect C-311 outside/inside air selection damper control motor connector, and measure the voltage at the harness side. Turn the ignition switch to the "ON" position. Measure the voltage between terminal 7 and earth. OK: System voltage Q: Is the check result normal? YES: Go to Step 5. NO: Go to Step 3.
| Step 3. Connector check: C-311 outside/inside air selection damper control motor connector Q: Is the check result normal? YES: Go to Step 4. NO: Repair or replace the connector.
| Step 4. Check the wiring harness between C-311 outside/inside air selection damper control motor connector (terminal 7) and the ignition switch (IG2). NOTE: Prior to the wiring harness inspection, check intermediate connector C-10, junction block connectors C-205 and C-203, and repair if necessary. 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 5. Check the outside/inside air selection damper control motor Refer to . Q: Is the check result normal? YES: Go to Step 6. NO: Replace the outside/inside air selection damper control motor.
| Step 6. Connector check: C-311 outside/inside air selection damper control motor connector and C-06 A/C-ECU Q: Is the check result normal? YES: Go to Step 7. NO: Repair or replace the connector.
| Step 7. Check the wiring harness between C-311 outside/inside air selection damper control motor connector (terminals 6 and 4) and C-06 A/C-ECU (terminals 2 and 3). NOTE: Prior to the wiring harness inspection, check intermediate connector C-10, and repair if necessary. Q: Is the check result normal? YES: Replace the manual air conditioner control panel (A/C-ECU). NO: Repair the wiring harness.
