Radio Antenna Module Test

WARNING: This page is about a different car, the 2010 Chevrolet Impala. However, it is still accessible from the selected car via links, so may be relevant.
  1. Inspect the radio antenna module grounding surfaces and the mounting hardware for any corrosion that may cause a poor ground.
    • If corrosion is noted, clean the grounding surfaces or hardware.
  2. Ignition OFF, disconnect the harness connector at the radio antenna module.
  3. Radio ON, verify a test lamp illuminates between the signal circuit terminal 1 and ground.
    • If the test lamp does not illuminate, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the radio.
  4. If all circuits test normal, replace the radio antenna module.
