Satellite Switch Circuit
Circuit diagnosis
DESCRIPTION
- The meter CPU receives satellite switch signals from the satellite switch in this circuit.
- The meter CPU sends satellite switch signals to the AFS ECU, and clearance sonar ECU using the BEAN lines. Each ECU controls every system based on these signals.
