Electronic Board
Steering rack is the main node of the steering system. The rack is responsible for transmitting power from the steering wheel to the front wheels. In order to facilitate and simplify the car driving as much as possible, power steering racks are mounted on the cars. Power steering system consists of three main components: electronic control system, hydraulic and pump unit. The electronic control board is located directly inside of the pump housing.
Breakdowns of power steering pump board
An electronic board is a "brain" of a power steering system. Electronics controls the operation of the power steering pump drive. When a board breaks, the power steering stops working. The cause of board failure can be oxidation or burnout of its elements.
How to determine if the electronic board is broken:
- pump does not turn on;
- pump turns on and off;
- pump has noise.
Power steering board most often loses its performance due to moisture attack. If there is, even slight damage in the pump casing, moisture, salt, sand can get onto the board surface. Such an aggressive environment leads to destruction of conductor strips, electronic components output and short circuits.
How does a driver understand that a board is broken?
- When the steering wheel, for no apparent reason, becomes tight, but can still turn a little, the “steering wheel” yellow icon is indicated on the dashboard - this is a reason to contact a service station.
- When other electronics break down along with a board, a driver sees the “steering wheel” red icon.
If such a trouble has occurred, you must urgently contact a specialized service. After the diagnostic, if the trouble is really in the control board, and not in the sensor, mechanics usually offer several solutions to the problem:
- to buy a board from the manufacturer;
- to buy a board with a pump;
- to search for a similar car with a working power steering board.
All of the above options are either difficult to implement or expensive.
We can offer you, at an affordable price, pump boards developed by our experts.
Production Process of Electronic Board
Our company has been selling used auto parts for many years. And we faced the following problem: mechanically, the rack can be in good condition, and the control board is out of order. In the case of the microcontroller failure, it is impossible to restore such a board, the firmware is not freely available, and it is quite problematic to buy a specific microcontroller.
That is why the engineers of our company took up the development of the board. Testing of the electronic board was carried out on the power steering pump SK 302R. Due to the features of the drive used in this pump, the control system is quite complex. And our engineers managed to repeat it. After additional tests, our experts finalized the board so that it works with diagnostic systems via the CAN bus and can be adapted to a specific car. Car ECU will not notice the difference between our boards and the original ones.
We do not rest on one's oars and, possibly, in the near future, engineers of MSG Equipment will make us happy with new developments in the field of electronic boards.
Electrohydraulic pump control unit SK302BOARD is intended to substitute a damaged original board. It should be installed instead of the faulty one. Original pump numbers to which this board is...
