Test A: Poor Reception - AM/FM
PINPOINT TEST A: POOR RECEPTION - AM/FMNormal Operation
The radio antenna, integral to the right quarter glass, receives AM and FM radio waves. The antenna module, which receives voltage from the audio control module (ACM) through circuit CME13 (YE/OG), sends the radio waves to the ACM through the antenna cable.
The noise suppression equipment reduces engine ignition and electrical systems interference transmitted through the speakers.
- DTC B2103 (Antenna Not Connected) - sets during the antenna connected test (part of the ACM self-test) when the signal strength is less than the pre-configured threshold value. In order for this DTC to set, the audio system must be tuned to AM, and the self-test must be run with the scan tool.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Antenna
- Antenna cable
- Charging system
- Ignition system
- Antenna module
- Noise suppression equipment
- ACM
