DTC Descriptor
DTC B0560 08
- Tachometer Circuit Signal Invalid
Circuit/System Description
The amplifier receives a discrete engine speed signal from the engine control module. The high signal circuit is a pulse-width modulated signal
from the engine control module. The low signal circuit provides a ground reference for the amplifier. The amplifier uses the engine RPM signal and
the inputs from three headliner mounted microphones to determine the frequency of undesirable engine sounds in the vehicle cabin.
Conditions for Running the DTC
* Engine running, Radio ON
