MAN TG3 Halt Brake (HSB) Wiring Diagrams – TGX/TGS Euro 6d (Q4 2020)

This official 2-page schematic from MAN Truck & Bus SE (Werk München) details the wiring logic for the Haltestellenbremse (HSB) or Halt Brake System, designed for MAN TG3 TGX/TGS Euro 6d vehicles. This system is typically installed in public service or waste collection trucks, enabling a controlled stop function at frequent stops.

🛠️ Coverage includes:

• Switches & Control:

  • S312.1 / S312.2 – Halt brake switch (SP008)

  • S652.1 – ASF application switch (Comfort Variant)

  • SP008 – Assigned to EIO1 or CVM module

• Relays & Fusing:

  • K359.1, K360.1, K361.1 – HSB control relays

  • F238.1 (FP002) – HSB system fuse

  • Relay sockets: X4455.1 / X4455.2

• Control Units & Pressure Detection:

  • A100.1 – Central electrical unit

  • A402.1 / A402.2 – EBS control unit

  • B230.1 / B230.2 – Pressure switch for parking brake status (B472)

• Connectivity & Variants:

  • CAN lines: CAN_1939_HI / LO

  • Multiple variant support:

    • Standard: With K361 relay

    • Comfort (ASF): Without K361, uses simplified control logic

  • Chassis interfaces: X6408, X203, X6301, X6396.1, XV805.1

Perfect for:

• Brake function diagnostics in stop-and-go commercial vehicles

• Configuring or retrofitting HSB systems in refuse vehicles

• CAN signal tracing between brake pressure switches and EBS logic

• Compliance and functionality checks of the hold-brake loop
