Mirror Replacement System Components

• Mirror display left (A1548.1)

• Mirror display right (A1549.1)

• Camera bracket roof left (B1250.1)

• Camera bracket roof right (B1251.1)

These electronic mirrors replace the conventional exterior mirror assemblies and transmit camera signals to internal display units.

---

Electrical Supply and Fuse Protection

The system is powered through:

• Central electrical system A100

• Fuse mirror replacement left (F1583.1)

• Fuse mirror replacement right (F1584.1)

Each display and camera circuit receives a protected supply through the vehicle electrical system.

---

CAN Bus and Communication Wiring

The mirror replacement system communicates through:

• CAN_H communication line

• CAN_L communication line

• O-CAN network integration

This communication allows the mirror displays to transmit camera data and status signals to the vehicle cluster and control systems.

---

Camera Signals and Heating Circuits

The diagrams include full wiring for:

• Camera signal lines (Signal_CAM-1 / Signal_CAM-2)

• Camera shielding connections

• Heating supply circuits (HEAT_P1 / HEAT_P2 / HEAT_N)

• Temperature signal wiring

These circuits support camera image transmission and heating functions for stable operation in cold environments.

Driver Control Interface

Mirror replacement control switches include:

• Driver control switch S1485

• Passenger control switch S1484

These switches replace the traditional mirror control switch when digital mirrors are installed.
