- Engine Control Module (ECU) Circuits Working Explanation
This video explains the ECU circuit board and demonstrates the way of crank and cam signal simulation to run the ECU and perform the different testing.
The engine ECU controls the injection of the fuel to the engine and the timing of the spark to ignite it. It determines the position of the rotation using a Crankshaft Position Sensor so that the injectors and ignition system are activated at precisely the correct time. It uses also number of sensor to read the status of the engine in order to run the engine at optimum performance.
The input to the ECU includes the following sensors:
Crank Position Sensor
Cam Position Sensor
Knock Sensor
Engine Coolant Temperature Sensor
Manifold Absolute Pressure or MAP Sensor
Mass Air Flow or MAF Sensor
Oxygen/O2/Lambda Sensor
Fuel Pressure Sensor
Engine Speed Sensor
Throttle Position Sensor
Thanks for your on explain the ECU
Glad to help
THANK YOU FOR YOUR EXPECTATION
Ecu with all its glory.... Amazing 😊
Thank you for the great explanation, it made our understanding much easier.
Heat the edges of the case with a heat gun and use ecu cover extractor tool to remove the cover. Makes the job a lot easier without destroying the ecu case
Can I convert a auto pcm to manual by removing a chip or rissistor?
Hello, and thank you for the video, it’s excellent and informative. I have a 2012 Volkswagen, the multimedia radio, the interior light and the sunroof no longer work but everything else works perfectly. The diagnosis tells me there is a control module fault with the code: 1048642. How can I repair this fault? Is it the soft out The hardware that is at fault? Thanks a lot for your help.
Start with the basics like checking fuses and resetting control modules. If those steps don't work, consider software updates and, if necessary, professional assistance for control module replacement. Remember to prioritize safety and consult with a qualified mechanic to ensure a proper and lasting repair. Good luck with getting your Volkswagen back in working order..
Hello, and thank you for the answer, please how to do resetting bcm?
Where can I find software upgrade?
The like is done.
Thank you for the videos.
Try to hard reset or sw reset
what if the ecu does not want to go out of the ground to the relay of the starter?
What is thr cost?

If the Electronic Control Unit (ECU) is not coming out of the ground to reach the starter relay, it suggests a possible issue with the ECU's connection or wiring. The cost of resolving this problem can vary depending on the specific circumstances and the extent of the repair required. It is best to consult a qualified mechanic or automotive technician to assess the situation and provide an accurate cost estimate for diagnosing and fixing the issue.
1999 honda civic rpm up and down i replace iac val what tha problem
If your 1999 Honda Civic is experiencing RPM fluctuations despite replacing the IAC valve, there are several other potential culprits to investigate. Check for vacuum leaks, clean the throttle body, and ensure proper idle speed adjustment. Also, inspect the TPS and MAF sensors, the fuel system, electrical connections, throttle cable (if applicable), and exhaust system for issues. Verify engine timing as well. If the problem persists, seek professional diagnosis and repair to restore a stable idle and RPM.
Hello can you repair continental getrag dc4 tcm
What can make the ECM spoiled
Static discharge and short circuit.
Next video... How to flash ecu
Noted...Thanks for sharing your concern. I will definately make one video related to this 😋
Diagram ecu ?????
Sir paano hende mag restart sir
Voltlog #225 ❤
I have son problem ,the scanner conect ob2, turn on the scanner ,the ecu not comunication to the scanner.what the problem
check for signs of water around ecu and wiring connectors
Depending on year might be a gateway module too , should be close to the obd port, you got a GoDiag breakout box or similar?
The speaker is egytian

I cannot understand your explanation.
