Audio System - No Radio/Audio Controls Locked-Up
SOURCE: Mitsubishi Tech Talk Article
TITLE: NO RADIO OPERATION AND/OR AUDIO CONTROLS LOCKED-UP AT IDLE
APPLIES TO: 2000-2004 Eclipse & Eclipse Spyder w/o Infinity Audio System
SERVICE TIP:
Using a non-resistor spark plug as a replacement can cause the audio system controls to lock up, or an inoperative condition of the audio system at idle.
The controls and the system may operate correctly at driving speeds. Certain frequencies created by the non-resistor spark plug can interfere with the
M-bus signal between the audio head unit and the multi-center display. Installing the required resistor-type spark plug will usually return the audio
system to proper operation.
