Sliding Roof System Components

• Sliding roof motor assembly (A473.1PT)

• Roof control unit (AV007.1)

• CVM control module (A1363.2)

• Central electrical system (A100.1)

• Sliding roof fuse (F402 – 10A)

These components form the electrical architecture responsible for roof opening, closing and motor control.

---

Roof Operating Switches

• Sliding roof open switch S1454

• Sliding roof close switch S1455

• Additional roof open/close switch variants S1459–S1464

• Sleeper roof operating interface wiring

These switches allow driver and sleeper control of the lifting roof mechanism.

---

CAN Bus and Electronic Communication

• CVM CAN communication routing

• D-CAN data bus integration

• User request signals transmitted through control module

• Motor open/close command routing

The sliding roof system communicates with vehicle electronics through the CAN network for control and monitoring functions.

---

Electrical Supply and Ground Routing

• Terminal +30 electrical supply routing

• Fuse-protected sliding roof circuit

• Ground network SYS_groundNet references

• Interior electrical system routing

These protected circuits ensure stable power supply for roof motor and control electronics.

---

Wiring Harness Interfaces

• Roof harness connector X6436

• Cab structure connector X6431

• System carrier wiring interfaces

• Roof electrical routing connectors

These harness references allow full diagnostic tracing of roof electrical circuits and wiring paths.

---
