System Description: Notes
The Multiplex Control System has four internal functions:
- Multiplexing (send multiple signals over shared wires)
- Wake up/sleep (runs at full power only on demand to reduce battery draw)
- Fail-safe (fixes or ignores faulty signals)
- Self-diagnosis (Mode 1 for the system, Mode 2 for input lines)
The system controls the function of these circuits:
- Entry light control
- Wiper/washer (including intermittent wiper)
- Interlock
- Keyless/power door lock
- Key-in reminder
