The VDO TSU 2.0 1391 dummy tachograph interface (AAA2726340021) is a CAN-capable simulator unit for 12–24V commercial-vehicle electrical systems, designed for vehicles not subject to tachograph requirements. It replaces MTCO 1324 and DTCO 1381 units while remaining plug-compatible, and forwards speed and motion information from a KITAS generator to the vehicle CAN bus to support correct speed, distance, power, and time display in the instrument cluster, with a battery-buffered real-time clock and user-adjustable time.

TSU 2.0 1391 Dummy Tachograph CAN Interface (12–24V)
The VDO AAA2726340021 (also referenced as VDO 1391-353132001100-AAA2726340021) is a TSU 2.0 1391 dummy tachograph designed for commercial vehicles that are not subject to tachograph obligations. Installed in an ISO 7736 / DIN radio-compartment format location, it replaces a DTCO or MTCO unit and enables speed and motion information from a KITAS generator to be transferred to the vehicle CAN bus, supporting correct instrument-cluster display of speed, distance, power, and time.
Features
- CAN-R settable: programmable CAN termination and CAN hardware configuration.
- Replacement unit: replaces MTCO 1324 and DTCO 1381 tachographs.
- Plug-compatible: designed to connect like MTCO and DTCO devices for straightforward integration.
- Battery-buffered real-time clock: maintains timekeeping with user-adjustable time via front-panel buttons.
- Peripheral outputs: supports common signals such as v-pulse and 4 pulses/m for connected devices.
Compatibility
- Commercial vehicles equipped for DTCO 1381 tachograph installations
- Commercial vehicles equipped for MTCO 1324 tachograph installations
- Systems using a KITAS generator as the motion/speed source
- Systems using KITAS type 2159 sensor
- Vehicle instrument clusters using a CAN instrument interface for speed data
- Installations using an ISO 7736 mounting frame in a DIN radio-compartment format
