Tachograph Solution Installation Guide

Introduction

IOX-COLD allows the GO™ device to read and download real-time data from digital tachographs. This data can then be viewed and analyzed in the Geotab Tachograph Module for the MyGeotab™ platform.

! IMPORTANT: IOX-COLD is compatible with all tachograph brands. However, the tachograph itself must support remote download (RDL) functionality. For more information, refer to the Remote Download (RDL) Capability section.

! IMPORTANT: Once the required installations between the IOX-COLD and its compatible solutions (Refrigeration unit and accessories, Thermograph, Tachograph, Expansions) have been completed, the IOX-COLD must be installed with GO9 devices as outlined in the quick start guide.

Tachograph connections

Tachographs have four ports: A (WHITE), B (YELLOW), C (RED), and D (BROWN).

✱ NOTE: The four ports are mechanically polarized/keyed and will only fit into the mating receptacle as explained. Do not force while fitting the connector.

✱ NOTE: Some tachographs are protected with a security seal that must be removed in order to proceed with the installation.

✱ NOTE: If installing in a Scania vehicle and the C connector (RED) is populated with wires in positions C5 and C7, and there are no wires connected to A4 and A8, see Scania Vehicles with Tachograph SRE6.x before installation.

✱ NOTE: If installing in a vehicle using Stoneridge SRE8.X or EFAS-4.10 tachograph and the C connector is being used by DSRC antenna, see How to connect CAN-C when it is occupied by the DSRC antenna before installation.

! IMPORTANT: The vehicle electronics are connected to the Tachograph by a pair of wires known as CAN-A (CAN bus), connected to the Tachograph Port-A (WHITE Connector), using the A4 and A8 pins. Never change connections in A or B connectors.

! IMPORTANT: Do not modify the provided C connector (RED). This connection cannot be shared, and there must never be multiple connections as this can cause interferences in the vehicle CAN Bus, which could cause malfunctions.

WARNING! If, at any point, a warning light illuminates on the vehicle dashboard or the vehicle stalls or has a marked drop in performance, shut off the engine, remove the device and contact Support. Continuing to operate a vehicle with these symptoms can cause loss of vehicle control and serious injury.

! IMPORTANT: After extracting the Tachograph, be very careful when leaving the tachograph hanging to avoid any cable damage.

Installation instructions

WARNING! It is highly recommended not to create any electrical connection (vehicle harness modification, splices etc.) between the Geotab devices (GO9 + IOX-COLD) and tachograph ports A and B (for example, power supply through the 3-wire harness or CAN bus connection). The Geotab Truck Solution is not designed to interface with these ports, and Geotab will not be responsible for any mechanical, electrical, or legal issues caused by a connection made to tachograph ports A and B.

Standard installation

Special case: first connection — real-time data

Case 1: A brown connector is already connected to tachograph Port D:

Case 2: VDO tachographs versions 1.3 or later:

For some VDO tachographs you will need additional parts:

1. VDO DTCO Update Card (client supplied)

1. Frontal connection Harness HRN-CL01S2 (C309).

Installation process:

Special cases: second connection — remote download

Case 1: VDO tachographs versions 1.2 and older

Case 2: Scania vehicles that had or have an SR6.x tachograph

This is a special case for all Scania vehicles which previously had or currently have a Stoneridge 6.x tachograph. Usually in those installations, tachographs have been or will be replaced with a newer model without modifying the electrical installation.

First, check the connectors A and C. This operation only applies if the vehicle is a Scania with a Stoneridge tachograph with the vehicle CAN bus connected to port C of the tachograph. This situation is easy to diagnose as there are no wires connected to A4 and A8. Before connecting the HRN-URTACHO02-A, make the following modifications as instructed in Stoneridge information bulletin NT2009/012:

Case 3: tachograph Port-C is occupied by the DSRC antenna

Some Stoneridge SRE8.X and EFAS-4.10 have the DSRC antenna connected to Port-C of the tachograph instead of Port-A of the tachograph.

There are different ways to detect if this is the case:

1. Sometimes, there is a T-Harness connected to Port-C of the tachograph. In this case, the T-Harness is connected to the FMS vehicle CAN bus and DSRC antenna. This doesn’t always happen.

1. In all cases, if the current C-Connector (red) is disconnected from Port-C of the tachograph, the tachograph will show this error on screen: Remote detection failure in Stoneridge and DSRC fault in EFAS.

Remote download (RDL) compatibility

It is important to know if the tachographs in your fleet are compatible with the remote download system. Based on the brand of your tachographs, there are different ways to do this. The following tool is used to check the compatibility between a tachograph brand and Geotab tachograph solution : Online RDL Check Tool.

Stoneridge

All Stoneridge models support remote download from revision 7 (REV7).

✱ NOTE: The OK Rule: If there is an OK button, then it supports RDL. Check your tachograph keyboard symbols:

! IMPORTANT: Check with a calibration tool (MKII or similar) that the following parameters are activated:
