DTC B1025, B1035, B1045, or B1055
Circuit Description

When the radio is powered up, the radio supplies low level audio signals to the speakers. If the vehicle is equipped with an audio amplifier, the amplifier will boost the signal sent to the speakers.
Conditions for Running the DTC

The test is performed when the radio switches from OFF to ON. The radio will continue to test for the fault once every 0.5 seconds.
Conditions for Setting the DTC

The radio sets a current status for this DTC when a short to ground or voltage is detected on any of the speaker channels for 1.5 seconds.
Action Taken When the DTC Sets

No sound is present from one or more of the speakers.
Conditions for Clearing the DTC

The fault condition is not present for 5 seconds.

What to do:Test the speaker outputs from the radio for short to ground or voltage. Inspect for poor connections at the harness connector of the radio. Reprogram the radio. Replace the radio.
