ABS control unit repair from a professional in Austria
As an Austrian professional for Electronics repairsWe also offer a low-cost ABS control unit repair. But not only ABS repairs are carried out by us. Our experienced technicians can also carry out other repairs to electronic vehicle components of all kinds. For example, we repair speedometers, electric steering systems, engine control units and navigation systems. In this article, we will go into more detail about ABS repairs.
The ABS control unit repair
An ABS control unit repair is necessary if the control unit no longer functions properly. The ABS control unit is an electronic component that takes over the function of the anti-lock braking system. The ABS regulates the brake pressure and thus prevents the wheels from locking during heavy braking manoeuvres.
The newer ABS control units have integrated anti-slip control and an Electronic Stability Program, thus providing even more driving safety in poor road conditions. Further information is available from the Wikipedia Anti-lock braking system Entry. If the ABS control unit is defective, it must normally be replaced. However, since a replacement is very expensive, we offer a cost-effective ABS control unit repair an.
Internal structure of the ABS control unit
In order to be able to carry out a professional ABS control unit repair, you must know and understand the internal structure of the control units. The ABS control unit, as in the article on the Engine control unit repair In the following, a distinction is made between normal circuit boards and ceramic circuit boards. With normal circuit boards, it is relatively easy to measure and replace the components; with ceramic circuit boards, it is not possible to measure or replace the components. For more information on repairing normal PCBs, see our news article Electronics repair from a professional or PCB repair and printed circuit boards.
The good thing about hybrid control units is that defects in components are not common. Mostly, the aluminium connections (so-called bondings) to the plug are damaged. With our special machine, we can professionally repair these bondings. You should not let amateurs carry out repairs on your hybrid control unit. Since they want to save the investment in the expensive special machines, they try to solder the connections.
This causes several problems at once. Aluminium does not bond with the solder, so this connection does not last long. In addition, it is no longer possible to bond to a contact surface that has been contaminated with solder. Due to this circumstance, the control units are irreparable after soldering!
Correct diagnosis of the anti-lock braking system
Before the control unit reaches us for repair, a fault diagnosis must be carried out on the vehicle. This diagnosis should not only include reading out the fault codes, but also checking the supply voltage, wheel speed sensors and evaluating the control unit parameters. Only through this important preliminary work can it be determined whether the fault really lies with the ABS control unit.
ABS Repair by Mosertronik Austria
In order for us to carry out the ABS repair, the control unit must first be removed and sent to us. We first disassemble and clean the control unit. Then we check the electrical components for defects or, in the case of hybrid control units, for defective bondings. After checking for defects, we prepare a cost estimate.
As soon as this is released, we replace the defective parts and seal the control unit. Then, if possible, we carry out a final functional test of the replaced components. If everything fits, we send the control unit back. You have to reinstall it in the vehicle and check whether all functions work properly.
Procedure via our online shop system
For a faster process, you can use our Online shop use. To do this, search for your ABS repair in our shop, select the type of handling, place the control unit in the shopping cart, make a normal check-out and send the well-packaged ABS with the printed PDF to us. If you have chosen immediate repair, the ABS will be repaired and returned without a cost estimate. If there is a price discrepancy, we will of course inform you in advance.
Known faults of ABS control units
Failures are becoming more frequent with some ABS control units. A good example is the ATE MK61, for which we even have a separate news article. VW ATE MK61 Repair Service created. With the other ABS control unit repairs, a common fault is related to the pump motor. Some control units also have problems with communication or with the wheel speed sensors.
Before you have an ABS control unit repair carried out by us, the fault in the vehicle must be diagnosed. Often the fault does not come from the control unit itself, but from the connected components, such as the wheel speed sensors.
