SUBJECT:
AM Band Radio Noise

INTRODUCTION

The purpose of this bulletin is to address engine ignition noise when listening to low output AM radio stations while the engine is running. Engine noise can be transferred to the rear glass antenna from the rear window defogger grid. To reduce the noise, a ground wire (radio cord assembly) may need to be installed.





PARTS INFORMATION

PRODUCTION LINE CHANGE

A ground wire has been added to the rear gate wiring harness in production starting in February 2005, with VIN 5*373702.

REPAIR PROCEDURES/INFORMATION:





1) Start by checking the basics, ground wires, grounding bolts, antenna leads, antenna grid, etc. Does the rear glass have window tinting? If so, that will cause poor radio reception. If everything checks out ok, proceed with installing a radio cord assembly.

2) Remove rear gate trim panel; refer to the applicable Subaru Service Manual for the procedure. Use extreme care not to scratch or damage the trim panel when removing or reinstalling.





3) Disconnect the wire connector from the terminal of the rear window defogger (driver's side). Connect the radio cord assembly between the rear window defogger terminal and the connector.





4) Remove the bolt from the rear wiper motor bracket (motor end) and install the round terminal end of the radio cord assembly and reinstall the bolt.

Note:
To ensure proper grounding, loosen and tighten the bolt four to five times to remove any paint on the threads. Afterwards, apply a small amount of grease to the threads to prevent rust.

5) Secure the radio cord assembly in place by using insulation tape as shown in Figure 3.

6) Reinstall rear gate trim panel.
