Service Information: Information on replacing the modular tachograph (MTCO) with a digital tachograph

Introduction
The digital tachograph DTCO is compatible with the supplied pre-installation on vehicle designed for installation of the modular tachograph MTCO. Therefore no major interventions or additional electrical whips are required for installation.
The DTCO is also electronically compatible with the vehicle, making possible the installation plug&play, and not requiring additional works of configuration or parameterization.
 After the later installation of the DTCO, it must be calibrated and assessed to ensure its correct operation and to attend the legal requirements. In order to carry out this procedure, the vehicle must be sent to an homologated INMETRO station.
 The PTC element of the tachograph power harness should be replaced from 1,5A to 2,70A. In case of no-replacement, the printing process will be interrupted.

Electronic tachographs are recognized through the dedicated CAN network between INS-TCO making it possible to view it on the instruments panel through the on-board computer navigation.

 The MB number A9584460133, refers to the MTCO tachograph. Completed the installation, the MB number corresponding to the DTCO will be A9584460433.

Ad-measurement

The tachograph has calibration parameters that are controlled metrologically by INMETRO such as:

 Vehicle Chassis Number

 Characteristic K factor

 Vehicle plates

 Speed limit excess

 Date and current time

 These parameters are subject to periodic inspection by competent authorities.

DTCO main screen

This screen indicates all the main information of the Digital Tachograph as well as the screen which the driver of the vehicle will be most familiar with

1 Speed conditions

2 Date Programmed in the Digital Tachograph in dd/mm/yy format

3 Local time, in hh:mm format

4 Vehicle totalizator odometer

5 Vehicle status:

 Resting/Stationary 

 In travel/Direction - 

6 Driver code –Linked driver The driver's code will only be correctly identified after the previous registration. In case there is no driver linked / identified, the symbol “?????” will be shown on the screen and in the case of direction, an audible alarm will be activated. To deactivate it press "OK".
 For the correct handling, configuration of the information and access to all the functionalities of the DTCO, refer to the User Instruction Manual , supplied with the appliance.
