Test A: Poor Reception
PINPOINT TEST A: POOR RECEPTIONNormal Operation
Audio waves are received by the antenna grid (located in the rear glass) and transferred to the audio unit through the antenna cable. The radio suppression equipment reduces interference caused by the electrical components of the ignition and charging systems. When the SEEK/SCAN button is pressed, the audio unit searches for a channel with sufficient audio signal strength and automatically stops when it reaches one.
- DTC B2103 (Antenna Not Connected) - sets when the antenna signal is lower than the pre-configured threshold value during the audio unit self-test.
This pinpoint test is intended to diagnose the following:
- Antenna
- Antenna cable
- Noise suppression equipment
- Charging system
- Ignition system
- Audio unit
