ANTENNA MODULE
DESCRIPTION
The antenna module is an electromagnetic circuit component designed to capture and enhance radio frequency signals in both the AM and FM broadcast bands. The antenna module is mounted to the right rear roof rail under the headliner. The modules mounting brackets also double as the ground circuit. The module has an electrical connector that connects to the integral radio antenna, located on the right rear quarter glass. There is also an electrical connector for battery voltage and a coax cable connector.
OPERATION
The antenna module receives both AM and FM radio signals supplied by the side window integral radio antenna system and selectively amplifies them. The amplified signal is then sent through the body length coax cable to the radio input.
REMOVAL
WARNING: Disable the airbag system before attempting any steering wheel, steering column, seat belt tensioner, side airbag, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to take the proper precautions could result in accidental airbag deployment and possible personal injury.
1. Disconnect and isolate the battery negative cable.
2. Remove the headliner as necessary to access antenna module.
3. Disconnect the electrical harness connector from the antenna module.
4. Disconnect the antenna module connector from the integral antenna.
5. Remove the mounting fasteners from the antenna module.
6. Disconnect the coax lead from the antenna module.
INSTALLATION
WARNING: Disable the airbag system before attempting any steering wheel, steering column, seat belt tensioner, side airbag, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to take the proper precautions could result in accidental airbag deployment and possible personal injury.
1. Plug coax into antenna module.
2. Position antenna module. Install and tighten mounting fasteners.
3. Connect antenna module lead to the integral antenna.
4. Connect battery power supply lead to antenna module.
5. Install headliner. (Refer to 23 - BODY/INTERIOR/HEADLINER - INSTALLATION)
6. Connect battery negative cable.
