Poor Reception or Interference on AM Band



SYMPTOM

Customer complaint of unsatisfactory AM radio station reception, or a popping noise from the speakers when operating electrical equipment such as the turn signals or brake lights.

NOTE:
Refer to the Honda PROformance tape "Radio Diagnosis" for troubleshooting information.

PROBABLE CAUSE

Poor ground connection between the antenna collar and car body.


CORRECTIVE ACTION

Improve the ground connection and tighten the antenna assembly mounting nuts in the proper sequence.





1. Use the appropriate special tool to remove the nut from the antenna base.



2. Remove the spacer and bushing from the antenna base. Remove the antenna mast. Refer to section 23 of the appropriate service manual for the proper procedure.



3. Inspect the antenna mast and inside of the mast housing for corrosion. If no corrosion is found, clean the mast and housing with Honda Brake Cleaner (P/N PC-HBC265) or equivalent. If either the mast or inside of the housing is corroded, replace the complete antenna assembly.

4. Reinstall the mast as shown in the service manual.

5. Remove the antenna motor mounting nuts and remove the antenna assembly from the trunk.

6. Using sandpaper or a drill motor with wire brush attachment, remove the paint from the underside of the fender around the edge of the antenna hole.

7. Clean and lubricate the threads on the antenna base with Honda Multipurpose Lube (P/N 08732-0003) or equivalent.



8. Reinstall the antenna assembly in the trunk. Install the spacer, bushing and nut. Using the special tool, torque the nut to 2.3 N-m (0.23 kg-m, 20 lb.in.).

NOTE:
For proper operation, the antenna motor mounting nuts must be loose when torquing the special nut.

9. Tighten the antenna motor mounting nuts. Test the antenna operation, and check radio reception on several AM stations.
