Test H: Radio Interference

WARNING: This page is about a different car, the 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, and 2004 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: If the Original Equipment Manufactured (OEM) audio unit has been replaced with an aftermarket unit, the vehicle may not pass this test. Return the vehicle to OEM condition before following this pinpoint test.

  1. Verify Generator Is Source Of Radio Interference

    Start engine and let idle. Tune radio to station where interference is present. Turn ignition off. Disconnect generator 3-pin harness connector. Start engine and let idle. Is the interference present with the generator disconnected? If yes, diagnose the in-vehicle entertainment system. If no, replace generator. See GENERATOR  under REMOVAL & INSTALLATION. Test the system for normal operation.
