Is the ECU the same as the transmission?
In the Automotive industry, the term ECU often refers to an Engine Control Unit (ECU), or an Engine Control Module (ECM). If this unit controls both an engine and a transmission, it is often described as a Powertrain Control Module (PCM).
Which is the NC pin, no pin and common pin?
There is only 3 remaining pins to determine which are the NC pin, NO pin and common pin. Set your multimeter to continuity test mode. Try to touch the probes of multimeter on remaining pins to determine which are the pins actually connected with each other.These pins actually consist of normally closed (NC) pin/pins and common pin/pins.
What kind of serial port do I need for ECU?
The ECU requires an RS232 serial connection. Desktop PCs and older laptops will have 9pin D shaped ports on them marked COM for this type of communication. If you have this port then this is the best to use for communication with the ECU. If your PC does not have one of these ports then you will need to use an adapter.
Which is the main processor in the ECU?
The operation of the main processor inside the ECU and the activation of many outputs is overseen by a monitoring microprocessor – essentially a second computer that makes sure the main computer is doing everything correctly.
What’s the pin number for a replacement ECU?
For the following procedure, use the PIN of the REPLACEMENT (USED) ECU. ## 4-digit PIN ## The PIN needs to be entered as 5-digit number in the New Value box. For example, if your PIN is 1234, enter 01234.

Can a Mercedes 300SL have a bad ECU?
The vehicle is actually a 300sl but there was no option to choose from. I was wondering if the crankshaft sensor andcam sensor were replaced and code 17 (open or bad crank sensor) cleared but comes right back after the engine is started a sign of a bad ECU? The vehicle starts and runs but mises a lot when accelerated.
Is there a problem with Mercedes Benz S550 ECU?
Answer: Yes, this is a common problem with the S550 ecu . What happens is that when the ecu gets hot it stars acting up. Try to spray some freon on the base of the ecu and see if the misfire continues. More than likely we will have to replace the ecu with part number A2731535679 Thanks Date Created: 2015-11-19 Name: Kim Jenkins
How is the ECU dependent on the drivetrain?
The engine and drivetrain are the most dependent on the ECU. Through a numerous array of electronic sensors, chips, and components within the vehicle, the ECU can transmit data feedback to the engine. The nature of this feedback will determine which function the engine will perform next.
How does the engine control unit ( ECU ) work?
The ECU can then perform an action on the engine, allowing the correct amount of power to control actuators precisely. These can include controlling fuel injector pulse width, exact timing of the ignition system, opening of an electronic throttle body or the activation of a radiator cooling fan.
How does the ECU work in an ABS system?
Requests from the Antilock Brake System (ABS) module may also be considered, such as for the application of traction control. Once the data has been collected by the ECU, the processor must determine output specifications, such as fuel injector pulse width, as directed by the software stored within the unit.
What does the ECU do in a car?
The ECU, or engine control unit, is a major component of your car’s onboard computer. It’s used to regulate many systems and subsystems in your car’s engine, drive train and other major components. There are many symptoms that can be associated with a faulty ECU. Here are some ways to tell if yours is damaged or faulty.
What happens if you have a faulty ECU?
For example, poor performance or unexplained drops in fuel economy or efficiency are often related to onboard car computer problems, or faulty ECU issues. A damaged ECU can cause problems when shifting gears in an automatic transmission, or cause sudden jerking or stopping that’s similar to transmission problems.
Is there a way to reset the ECU?
This is the main way to reset the ECU. Be warned that going this route will clear out all presets including those for your radio, seats, navigation, etc. This is the easiest option and potentially the most annoying because it forces you to reset the settings.
How does the TCU work with the ECU?
The TCU process, along with the ECU, will certainly work cooperatively. They will definitely try to get to know your driving technique. They will certainly check your driving pattern and take care of that too. When it is done with the TCU as well as the programming of the ECU, you should take your car for a ride.
Disconnect the battery and Switch the ignition key to the on position for about 15 minutes should reset the ECU Can a ECU be reset? Yes, all ECU (Engine Control units) can be reset and be should reset once per manufacturer’s guideline for a smooth relearn process or upon installing a replacement unit.

Which is the correct formula for the ECU?
The ideal mixture, where all of the injected fuel is combusted and all oxygen is consumed by this combustion, is known as ‘stoichiometric’ or often as ‘Lambda’. At stoichiometric conditions, Lambda = 1.0. The Exhaust Gas Oxygen Sensor (Lambda sensor, O2 Sensor, Oxygen Sensor or HEGO) measures the amount of oxygen left over after combustion.
