Hyundai Electrical System Failure

We repair electronic control units of any car systems.

Some of these can be prevented, while others may happen without warning.
Child car seat failure: Keep an eye out for seat recalls. Are you using it right? Are you strapping the seat correctly to the vehicle? Do the instructions read clearly?

Airbag failures (Inadvertent deployment, late deployment, failed deployment): Check for recalls. You should also check the crash history if you buy a used car.

Transmission malfunction: Make sure your car does not overheat (a common factor for transmission issues), ensure there is no leakage, check fluid levels, and ensure the liquid is not dark or dirty.

Defective Seatbelts: It is difficult to avoid this because a seatbelt can seem like it is in working order until an accident occurs and then it is too late. What you can do is check for seatbelt recalls. Ford and Chevy have both recently had recall due to seat belt malfunctions. Toyota is currently going through seat belt lawsuits due to defective seatbelts on the Toyota Prius.

Vehicle rollover roof crush: There is no way to avoid this, but if you or a loved one has been involved in a vehicle rollover and the roof of the vehicle crushed, then you need to call an Attorney immediately.

Car stalling due to ignition defect: This can lead to a loss of control of the vehicle. AutoZone offers an ignition module test to customers.

Defective Steering component (axel, wheel): Does your steering wheel have a rough or loose feel to it? Does your car have a little extra “bounce” when it goes over a speed bump? Are there noises when you steer? Is the wear on your tires uneven?

Brake failure or malfunction

Even though it is uncommon, an accident resulting from brake failure can be disastrous and even deadly. Some of the warning signs of brake failure include the brake warning light coming on, your vehicle jerking to a stop or pulls to one side when you use your brakes, pumping the brakes to get them to work right or having one or more wheels excessively hot after short drives.

Floor mat and/or accelerator

Toyota has been dealing with product liability lawsuits over their Toyota Prius and also Lexus models. Ford has also seen its share of floor mat issues. Many car companies have taken note of this and most new models now have floor mats that are meant to stay in place and not get in the way of the driver and the gas / brake pedals. Sudden acceleration lawsuits happen. If you have an older car or a vehicle that comes with loose floor mats, check to make sure there has not been a recall.

ECU Repair in Dubai | We repair electronic control units of any car systems

When it comes to the on-board computer of a car, first of all, this term refers to the electronic control unit (ECU or ECU in English-speaking countries) is a universal definition for any subsystems that control electrical circuits and mechanisms in a car.

For example: Esud controller (ECM) controls the operation of the engine. transmission control module (TCM) ensures the operation of robotic gearboxes of such car brands as Ford or Volvo. Electronic control unit for anti-lock braking system (ABS) guarantees “smart” braking, etc. In modern cars, the number of built-in ECUs can reach 80 units or more

Why do you need an ECU?

Any modern car is stuffed with a huge number of various sensors, environmental monitoring devices, electronic circuits of a narrow specialization and other “devices”, each of which performs a limited role and ensures the operation of a specific node. But they are not interconnected – it is a set of ECUs (electronic control units) of various specifications that provides information processing and is a kind of “brain” of the car’s subsystems.

The car’s computer is involved every second: the system receives “input” information from the sensors installed on the units, compares the parameters with the specified standards, and during the cycle corrects the work of the slave devices using the algorithms stored in the memory. A set of interconnected electronic units implements the “incoming impulse = reaction” scheme, ensuring the joint operation of the ignition, gasoline pump, injectors, suspension, brakes, etc.

What devices are controlled by the ECU? First of all, these are condition tracking sensors:

  • Engine temperature
  • Oxygen supply
  • Position/Stability
  • Levels of liquids in nodes
  • Idle
  • Outside temperature
  • Current speed
  • Auto network voltage
  • Fuel injection
  • ABS operation
  • Pedal position
  • And others …

Faults and repair of the computer

To diagnose a malfunction, you do not need to try to open the housing of the electronic unit with an improvised tool! Such actions are almost guaranteed to lead to the failure of the computer even if the breakdown was minor!

To diagnose a high-tech device, only special equipment connected to the test ports should be used.

We independently determine deviations in the operation of the unit:

  • The engine runs unevenly / stalls or turns are “lost”;
  • Part of the secondary systems of the car is blocked;
  • The display gives errors and / or the car refuses to start;

It is very frustrating to face such problems. The control unit itself is considered a reliable element of the system and costs decent money, especially if designed for expensive cars with a lot of additional options. But nothing lasts forever and ECUs also periodically fail due to overload, moisture ingress, or mechanical damage. A common cause of breakdown is budget “chip tuning” by garage craftsmen.

If the car’s systems began to fail due to improper operation of the computer, do not despair, because there is always a chance to bring the control unit back to life. In the event of corrosion and destruction of contacts, the probability of restoring the board is very high. The main thing here is to give the module for repair to a reliable master who will delve into the problem and fix the problem with minimal intervention. In this case, even the old electronic unit will serve its owner for more than one year.

Stages of repair of the electronic control unit

  1. Obtaining maximum information about the causes that led to the failure of the ECU, external manifestations of problems, a list of errors that occurred during the initial testing.
  2. Checking the response of the block in our laboratory, diagnostics of ports and system integrity.
  3. In the presence of “physical” damage (cracked tracks, burnt elements, short circuit, etc.) – troubleshooting and subsequent full testing for compliance with the declared characteristics.
  4. In the event of a software failure, updating and restoring the software to a working level with the elimination of all errors on the stand.
  5. Completion of ECU repair and final tests until it fully complies with the standard of this device.
