Test G: Radio Interference

NOTE: If the Original Equipment Manufactured (OEM) audio unit has been replaced with the aftermarket unit, the vehicle may not pass the following test. Return the vehicle to OEM condition before proceeding with this pinpoint test.

  1. Verify Generator Is Source Of Radio Interference

    Start and run the engine. Tune the radio to a station where the interference is present. Turn ignition off. Disconnect generator single wire connector (Black/Orange wire). Start engine. With the engine running, is the interference present with the generator disconnected? If yes, diagnose the in-vehicle entertainment system. If no, install a new generator. See GENERATOR  under REMOVAL & INSTALLATION. Test the system for normal operation.
