What is ECU testing?

Our ECU testing facilities allow us to pin point the faults that lie behind the ECU failure if indeed there is one. We would carry out varies tests and assessments to ensure the units operation meets the OEM requirements.

Why does an ECU fail?

An ECU can fail for various reasons and its not as simple as it may sound. ECU’s have circuits that operate various parts of the vehicles. Communication faults generally would be the symptoms of an issue with the unit, faults would typically be a voltage spike or water ingress causing a burn out of the units PCB.

Has my AdBlue Pump failed?

Adblue pump failures are very common in commercial vehicle and public transport sectors. Failures in the main come from a lack of maintenance of the systems, lack of maintenance can cause crystallisation issues which also lead to the system not operating correctly. Other failures can range from communication faults, Oil, coolant or fuel contamination, blowing fuses, water Ingress, various intermittent faults, various sensor faults, fault codes In units, connector and pin damaged.

How much do AdBlue Pumps cost?

Adblue pump costs can range dependant on what’s requested from the unit its self. If we a traditionally pumping unit the costs are lower than that of a unit that is programmed specifically to the vehicles chassis.

Where are AdBlue Pumps located?

Pumps on a bus/coach would be located at the rear of the vehicle close to the exhaust system and in contrast to a truck these would be located on the chassis of the tractor unit toward the second axle close enough to the exhaust system.

What Instrument Clusters can we remanufacture?

There are a few instrument cluster manufacturers but in the main the manufacturers within our industry consist of Continental (Germany), DENSO (Japan), Magneti Marelli (Italy), Robert Bosch (Germany), Here at ATT our team have the capabilities to repair and restore these products back to OEM standard.

What is Instrument Cluster testing?

Instrument cluster testing is an instrument cluster that is placed on a test bed and checked for various signals, voltages and visual dial checks. Here at ATT, we have all those in house capabilities.

What is an Instrument Cluster?
