MAN TG3 Seat Wiring Diagrams – Driver, Passenger & Middle Seat Heating, Occupancy Sensors, Belt Signals & CAN System

This technical wiring manual contains the complete electrical schematics for the seat electrical systems used in MAN TG3 trucks.

The diagrams include the full control architecture for seat heating supply, seat occupancy detection sensors, belt monitoring feedback signals, CAN communication routing and electrical supply connections for driver, passenger and middle seats.

All circuits include connector identifiers, system references and grounding architecture required for professional diagnostics, repair or seat system troubleshooting.

Seat System Components

• Central electrical system (A100.1)

• CVM control module (A1363.2)

• EIO1 control module (A1361.1)

• Seat heating fuse (F198.1 – 10A)

• Driver seat connector (X4587)

• Passenger seat connector (X6860)

• Middle seat connector (X6861)

These components form the electrical architecture responsible for seat power supply, heating and monitoring functions.

CAN Bus and Electronic Communication

• I-CAN communication through CVM module

• CAN communication through EIO1 module

• Seat belt feedback signals to control modules

• Occupancy detection signal routing

The seat electronics communicate with vehicle control modules through the CAN network for monitoring and safety functions.

Seat Power Supply and Sensor Routing

• Terminal +15 supply routing for driver seat

• Passenger seat heating and belt supply wiring

• Middle seat belt and occupancy supply wiring

• Ground network routing for seat sensors

These circuits provide electrical supply and signal routing for seat heating, safety and detection systems.

Wiring Harness Interfaces

• Driver seat harness interface

• Passenger seat harness interface

• Middle seat separation connector

• System carrier wiring harness routing

These harness interfaces allow full diagnostic tracing of seat electrical circuits and connector paths.

Diagnostic Use Cases

• seat heating not working

• seat occupancy detection failure

• seat belt warning signal faults

• CAN communication seat errors

• electrical supply issues to seat systems

• connector or harness routing faults
