Mercedes Trucks TEMIC Bench Cable (cable 144300KPWR required)
Bench cable for Temic control units on Mercedes heavy-duty vehicles, with the control unit removed.
This harness connects directly to the Temic control unit connector once removed from the vehicle. It allows work on units where OBD access is not possible, as well as on units removed for repair or replacement.
The setup requires an additional power supply, as the control unit connector does not supply current.
Specifications
- Alientech reference: 144300K274
- Bench connection on removed control unit
- Compatibility: Temic control units, Mercedes Actros, Arocs and Atego
- Power cable 144300KPWR required
- Compatible with KESS3
The AMP superseal power cable (ref. 144300KPWR) is essential for this setup to function.

ALIENTECH KESS3 CABLES
An official accessory for every vehicle
Each cable in the Alientech range is designed and certified to ensure stable and secure communication between your KESS3 and the target ECU. Unlike generic cables, official Alientech cables are developed in parallel with protocol updates: when a new vehicle is supported, the corresponding cable is bench-validated by Alientech engineers before commercialization.
No risk of interruption during writing, no data loss, no damaged ECUs.
This is the standard expected in a professional workshop.
Choosing the right accessory for your vehicle
Alientech cables are divided into three families depending on how they connect to the ECU.
OBD cables connect directly to the vehicle's diagnostic port, without disassembly. This is the fastest method for vehicles that support it.
Bench cables allow you to work on the removed ECU, connected via its external connector. No opening of the housing is necessary: ideal for ECUs inaccessible via OBD or to secure intervention on a fragile module.
Boot cables and multifilar cables provide direct access to the microprocessor on an open electronic board. Essential for locked ECUs or in case of forced rewriting after a blockage.
FULL RANGE
Cables for all industries
The Alientech cable range covers all vehicles supported by KESS3: cars and light commercial vehicles, motorcycles and ATVs, trucks and buses, agricultural equipment, boats and jet skis.
Each reference is identifiable by its Alientech number (format 144300KXXX) and corresponds to a specific connector and protocol.
OBD Mode
Fast communication directly from the passenger compartment. The new-generation OBD cable unifies all market protocols and automatically manages complex multiplexed architectures (Ethernet, FlexRay, CAN Bus, K-Line, J1850).
Bench Mode
Intervene directly on the external connector of the previously removed ECU. This method guarantees a full read without opening the ECU casing, eliminating any risk of material damage.
Boot Mode
Access the microprocessor directly by connecting to the open electronic board. Essential for the latest generation of high-security ECUs, or to force a complete rewrite on a locked ECU.
The cable: the first link for a safe intervention
An Alientech cable alone is not enough: it integrates into a complete ecosystem. The main OBD cable (144300KOBD) or the universal cable (144300KUNI) serves as the base, and adapter cables like this one complete the connection for vehicles with non-standard sockets. For Bench and Boot operations, flat cables, adapters, and positioning frames complete the setup.

FAQ
What is an Alientech cable for KESS3?
Alientech cables are official accessories designed specifically for the KESS3. Each cable corresponds to a specific connector and ensures stable and secure communication between your tool and the target ECU.
What is the difference between an OBD cable, a Bench cable, and a Boot cable?
An OBD cable plugs directly into the vehicle's diagnostic port without disassembly. A Bench cable allows work on the ECU once removed, via its external connector. A Boot or multi-wire cable provides direct access to the microprocessor on an open electronic board, for locked or blocked ECUs.
Can I use these cables with a KESS3 Slave?
Yes, all Alientech cables are compatible with KESS3 Master and KESS3 Slave. The vehicle's corresponding protocol must be enabled on your tool.
Does a cable require an activated protocol to be used?
Yes. The cable provides the physical connection, but the corresponding protocol must be enabled on your KESS3 to communicate with the ECU. Without an active protocol, the cable alone is not enough.
How do I know which cable to use for my vehicle?
Consult the Alientech Suite database for all supported vehicles and the required cable for each ECU. Your RS-Tronic dealer can also assist you.
Are Alientech cables compatible with other remapping tools?
No, the cables in the 144300K and 144300T range are developed exclusively for the Alientech KESS3 ecosystem. They are not compatible with third-party tools.
Can a cable damage the vehicle's ECU?
An official Alientech cable used correctly with a validated protocol presents no risk to the ECU. This is precisely the advantage of official accessories over generic, uncertified cables.
