Providing Diagnostics for All Commercial Vehicles


Brett Ekins, Technical Manager at Eclipse Automotive explains how to identify and rectify a fault in a MAN TGX anti-collision system.

Eclipse is the largest supplier of multi-brand diagnostic products in the Commercial Vehicle sector, with their innovative Eclipse Testpad Extreme® PRO running Jaltest software helping many businesses to improve vehicle and machinery performance.

There are more than 2,500 Eclipse Jaltest packages in use covering a wide range of commercial vehicles including all major manufactures.

Identifying faults on many modern commercial vehicles is increasingly difficult given the rising levels of technology employed by manufacturers. The analysis of the Anti-collision system on a MAN TGX Euro 6 model shows how the Eclipse Jaltest package is becoming the go-to diagnostic solution for the commercial industry.


The Problem

A Man TGX Euro 6 has come into the workshop with a forward-looking radar fault being displayed on the dash.

As this is a key safety system on the vehicle it has been immediately defected and taken off the road.

Initial Assessment

The Technician makes an initial diagnosis of the ROM2, Forward-looking radar system to check if any fault codes have been logged in the ECU that is causing the warning light to be on the dash.

One active fault is listed showing the ECU has detected a fault with the front radar sensor control unit (code 4013). With this type of fault before replacing any components we will need to check all the wiring to this component using all the technical data available on Jaltest.


Correcting the Fault

Using Jaltest we can identify the power feeds; earths and the CAN communication lines required to the control unit using the in-depth wiring diagrams and technical data available within the Jaltest software.

The technician has confirmed all the wiring is ok and he is getting all the correct measurements therefore it is determined the front radar sensor is at fault and requires replacing.

The front radar sensor after replacing will need to be programmed to the vehicle using Jaltest however it will also require the use of Jaltest ADAS.

With the help of Eclipse’s Vehicle technical support team and using the ADAS calibration equipment, the component was easily fitted and calibrated and the fault cleared meaning the vehicle was back on the road the same day.


Initial Assessment Eclipse Jaltest ADAS

Eclipse Jaltest ADAS package is a multi-brand diagnostic and calibration solution for all commercial vehicles using the Jaltest Multi-brand software and the ADAS calibration equipment we are able to carry out all calibrations of the anti-collision systems including lane departure, emergency braking adaptive cruise control and front radar sensors either due to a faulty component or a windscreen replacement.

Eclipse Jaltest ADAS can carry out all static and dynamic calibrations for all makes of commercial vehicles.

With Eclipse being able to not only offer the Ability to diagnose the fault but to also allow the new component to be calibrated with our Multi-brand ADAS solution it means the vehicle does not have any unnecessary down time due to waiting for a third part to carry out the calibration needed to make this vehicle safe and legal to drive on out roads making the Eclipse Jaltest package the go to multi-brand solution for the commercial vehicle sector.
