This bulletin is being revised to update the Parts Information. Please discard PI0168.

Condition/Concern
Some customers may comment that the AM radio reception is poor, normally manifested as increased static. Other
radio reception (FM and XM) performs as expected.
The antenna coaxial cables female connector is a segmented cylinder comprised of 6 fingers (or tines) that maintain
electrical connection with the cylindrical male connector by exerting an inward/clamping force against it. The fingers
may be spreading and compromising the electrical interface between male and female connector. This spreading
results in an unacceptable rise of resistance in the AM/FM ground path, which comes across as static on the AM
band. The spreading of the finger may apply to one or all connection points of the AM/FM coaxial cable, from the
antenna to the radio. Also, disconnecting/reconnecting the coaxial cable may aggravate the condition.

Recommendation/Instructions
Note: There are multiple antenna connections in the body wiring harness. Only the AM/FM antenna coax
connections need the sleeve. If the coax is equipped with one way connectors, they are black in color. If the coax
has a duplex (two way) connector that is dark (mustard) yellow in color and you are unsure which one is the AM/FM
connection, install a sleeve in both connectors in the dark (mustard) yellow duplex connector.
Install one coaxial cable sleeve, P/N 20972763, on the female side of the coax connector. Perform this operation on
all AM/FM coaxial cable connection points (from the antenna to the radio). One sleeve per connection point will be
required. Use the following steps for installation of the sleeve.

1. Position sleeve with the flared out side towards the female connector opening.

2. Push in the sleeve as far as you can with your finger.

2451196

3. The sleeve may not appear to be pushed all the way down; this is normal. Reconnect the coax cables.
Use the following graphic information for sleeve installation locations. Refer to SI for specific procedures to access
these locations.
