Diagnostic Procedure
ANTENNA NOT CONNECTED - SDARS SYMPTOM CHART
| TEST | ACTION | APPLICABILITY |
|---|---|---|
| 1 | Turn the ignition off. Disconnect the Satellite Receiver Antenna connector. Disconnect the Satellite Radio Receiver harness connectors. Measure the resistance of the TERR Signal circuit between the Satellite Receiver Antenna connector and the Satellite Radio Receiver connector. Is the resistance below 5.0 ohms? Yes --> Go To 2 No --> Repair the TERR Signal circuit for an open. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 2 | Turn the ignition off. Disconnect the Satellite Receiver Antenna connector. Disconnect the Satellite Radio Receiver harness connectors. Measure the resistance between ground and the TERR Signal circuit. Is the resistance below 5.0 ohms? Yes --> Repair the TERR Signal circuit for a short to ground. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 3 |

| 3 | Turn the ignition off. Disconnect the Satellite Receiver Antenna connector. Disconnect the Satellite Radio Receiver harness connectors. Measure the resistance of the Satellite Signal circuit between the Satellite Receiver Antenna connector and the Satellite Radio Receiver connector. Is the resistance below 5.0 ohms? Yes --> Go To 4 No --> Repair the Satellite Signal circuit for an open. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 4 | Turn the ignition off. Disconnect the Satellite Receiver Antenna connector. Disconnect the Satellite Radio Receiver harness connectors. Measure the resistance between ground and the Satellite Signal circuit. Is the resistance below 5.0 ohms? Yes --> Repair the Satellite Signal circuit for a short to ground. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 5 |
All |
| 5 | Turn the ignition off. Check the antenna for physical damage. Disconnect the Satellite Receiver Antenna connector. Disconnect the Satellite Radio Receiver harness connectors.
NOTE:
Check the related wiring terminals for corrosion, damage or terminal push out. Repair as necessary. Using the schematics as a guide, inspect the wire harness and connectors. Pay particular attention to all Power and Ground circuits. Replace the Satellite Receiver Antenna in accordance with the service information. Turn the ignition and the radio on and place the radio in Satellite mode. Does the DTC return? Yes --> Go To 6 No --> Repair is complete. Perform BODY VERIFICATION TEST - VER 1 . |
