Circuit/System Testing
WARNING: This page is about a different car, the 2007 Saturn Outlook. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition OFF, disconnect the DRR antenna coax cable from the DRR. Connect the test antenna to the DRR.
- Turn the ignition ON, radio ON tuned to XM. Verify that DTC B1259 is not current.
- If the DTC B1259 is still current, replace the DRR.
- Ignition OFF, disconnect the radio antenna base from the DRR coaxial cable. Test the resistance of the DRR antenna coaxial cable center conductor from end to end. Verify the resistance is less than 5 ohms.
- If the resistance is greater than 5 ohms, replace the DRR antenna coaxial cable.
- Test the resistance of the DRR antenna coaxial cable outer shield from end to end. Verify the resistance is less than 5 ohms.
- If the resistance is greater than 5 ohms, replace the DRR antenna coaxial cable.
- Test the resistance of the DRR antenna coaxial cable between the center conductor and the outer conductor. Verify there is infinite resistance between both conductors.
- If there is less than infinite resistance between the inner conductor and the outer conductor of the DRR antenna coaxial cable, replace the DRR antenna coaxial cable. If the DRR antenna coaxial cable tests normal, replace the radio antenna base.
