Jaltest ETM (Electronic Test Module)

ETM is an additional module included in Jaltest used to verify and check different electronic modules and sensors installed in commercial vehicles.

When checking and testing these components directly, without connecting through electronic control units, the verification process is quicker and diagnostic errors due to elements outside the component (connectors, cables, ECUs, etc.) are avoided.
ETM can perform diagnosis on: 

EBS modulators from Wabco and Knorr-Bremse.
Speed sensors in ABS and EBS systems.
Brake pads wearing sensors in Knorr-Bremse and Meritor calipers.

To connect to such components, the following cable set is required:  

The additional module ETM is connected to the desired module through the corresponding cable. Moreover, power supply from the vehicle batteries is required.  

When detecting a common failure in the EBS modulator, we would use a diagnostics tool to find out the error codes. Then, we will check the electrical installation, the control units and the modulator, in order to find the faulty component. What is the advantage of using ETM? We will connect directly to the modulator to check its operation in an easy and quick way. 

This way, we are saving much money and time. We avoid mistakes and removing the modulator when it is in perfect conditions, because maybe the problem is just in the wiring. 

We must follow a similar process if we want to check speed sensors
Or brake pads wearing sensors:  
Jaltest ETM is a very useful tool that saves much time and money in our day a day. An exclusive device in the market, manufactured by one of the most experienced companies in diagnostics for commercial vehicles
