DIAGNOSTIC PROCEDURE - ATC TEMPERATURE CONTROL INCORRECT IN SUN/SHADE
| TEST | ACTION | APPLICABILITY |
|---|---|---|
| 1 | Perform the *ATC System Test found in the Heating & A/C Category. Repair all Diagnostic Trouble Codes found while performing this test. Verify that the symptom ATC Temperature Control Incorrect In Sun/Shade is still present. Is the symptom still present? Yes --> Go To 2 No --> Test Complete. |
All |
| 2 | Turn the ignition off. Disconnect the Sun Sensor/VTSS LED harness connector. Turn the ignition on. With the DRBIII® in Sensor Display, read the Sun Sensor voltage. Is the voltage below 4.8 volts? Yes --> Replace and program the Body Control Module in accordance with the Service Information. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 3 |
All |
| 3 | Turn the ignition off. Disconnect the Sun Sensor/VTSS LED harness connector. Turn the ignition on. Measure the voltage of the Sun Sensor Signal circuit. Is the voltage above 5.2 volts? Yes --> Go To 4 No --> Go To 5 |
All |
| 4 | Turn the ignition off. Disconnect the Sun Sensor/VTSS LED harness connector. Disconnect the Body Control Module C1 harness connector. Turn the ignition on. Measure the voltage of the Sun Sensor Signal circuit. Is the voltage above 0.2 volts? Yes --> Repair the Sun Sensor Signal circuit for a short to voltage. Perform BODY VERIFICATION TEST - VER 1 . No --> Replace and program the Body Control Module in accordance with the Service Information. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 5 | Turn the ignition off. Disconnect the Sun Sensor/VTSS LED harness connector. Connect a jumper wire between the Sun Sensor Signal circuit and the Sensor Ground circuit in the Sun Sensor harness connector. Turn the ignition on. With the DRBIII® in Sensor Display, read the Sun Sensor voltage. Is the Sun Sensor voltage below 0.2 volts? Yes --> Replace the Sun Sensor in accordance with the Service Information. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 6 |
All |
| 6 | Turn the ignition off. Disconnect the Sun Sensor/VTSS LED harness connector. Connect a jumper wire between the Sun Sensor Signal circuit and ground. Turn the ignition on. With the DRBIII® in Sensor Display, read the Sun Sensor voltage. Is the Sun Sensor voltage below 0.2 volts? Yes --> Repair the Sensor Ground circuit for an open. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 7 |
All |
| 7 | Turn the ignition off. Disconnect the Sun Sensor/VTSS LED harness connector. Disconnect the Body Control Module C1 harness connectors. Measure the resistance of the Sun Sensor Signal circuit between the BCM C1 harness connector and the Sun Sensor harness connector. Is the resistance below 5.0 ohms? Yes --> Go To 8 No --> Repair the Sun Sensor Signal circuit for an open. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 8 | If there are no possible causes remaining, view repair. Repair Replace and program the Body Control Module in accordance with the Service Information. Perform BODY VERIFICATION TEST - VER 1 . |
