INSPECTION PROCEDURE
INSPECT SATELLITE SWITCH
CHECK HARNESS AND CONNECTOR (COMBINATION METER - SATELLITE SWITCH)
METER / GAUGE SYSTEM - Satellite Switch Circuit |
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.
