- Antenna Ground Circuit Short to Ground

Diagnostic Fault Information

Circuit/System Description

The Digital Audio Broadcast (DAB) radio receiver receives a digital radio signal via the digital radio antenna. This signal is passed to the DAB

module through the digital radio antenna coax. The DAB module sends a varying AC mV signal through separate left and right audio circuits (+

and -) to the radio. The voltage amount and rate of change is dependent upon the type of signal being received. The radio then processes these

signals and passes the audio to the amplifier.

Conditions for Running the DTC

The ignition is ON.
