The importance of the ECU
Your car’s computer is an important part of your vehicle, and as such it is vital that you know how to reset it when required. A lot of people might be skeptical about this at first but in reality it’s a pretty simple process. A car ECU (also referred to as an Engine Control Unit) operates under a programme which makes sure everything within the vehicle runs smoothly.
##How To Reset Car Computer? In order to complete a reset on your car’s ECU, it is recommended that you follow these steps: Make sure the battery cables are disconnected from both the car and from their respective terminals for 30 seconds before reconnecting them.
Then start up your engine with no additional input coming from any other devices or anything else happening outside the vehicle. Continue driving until the red ‘Service Engine Soon’ light goes out before shutting off your ignition switch again. Once done, make sure not to use any other power sources for approximately 20 minutes so that everything has time to synchronize properly before using electric accessories again.

How to reset the ECU
Starting with identifying what exactly is wrong with your vehicle. Read and study these tips on how to reset engine control module and a variety of other automotive problems.
The key is knowing what you want, before you ask it from the ECU chip which can be difficult for newbie mechanics and drivers alike. Most automotive shops will recommend that you replace your faulty part instead of an ECU chip that may cost thousands of dollars. For those who don’t know how to fix or change their malfunctioning parts like the water pump, have them replaced by someone who does because there are risks involved when trying to do it on one’s own without experience in repairing engines properly.
A trained mechanic will be able to get the right kind of results as well as help identify any other issues with your engine if they show up down the line. If you’re looking at how to reset engine control module yourself, make sure you read up on how-to guides before diving into this project.
There is no need to rush this process since everyone has different models which means things could go differently depending on what year your car was manufactured in (i.e., 2001 vs 2004). It would not hurt though if one were to study beforehand so they won’t break anything else during their journey towards fixing the problem at hand such as messing up connections that might lead elsewhere in your system causing more damage than just going through each step systematically and slowly as recommended for beginners.
What you need to know before you start
If you’re having a problem with your car and don’t know what it is, it might be worth trying a reset. This can fix many issues and is relatively easy. You will need:
– A screwdriver
– A jumper cable or set of jumper cables
– A fully charged battery (to power computer)
– Computer (to find pinouts)
– Paperclip (or wire)
– Electrical tape (optional)
What Will Happen If I Reset My ECU?
If you reset your ECU, it will probably cause a check engine light on. This is not something that you want to do because if you don’t know what caused the check engine light, then it can’t be fixed.
There are two different ways in which you can reset an ECU: clearing codes and firmware updates. The difference between these two methods is that one will erase codes while the other will rewrite them. It is important to get rid of old codes before they build up or they could lead to problems later on.
One way to clear out all codes at once is by turning off the ignition, unplugging the battery for 15 minutes and then reconnecting it before turning the key back on.
A more time-consuming but much safer way of doing this would be plugging in a scanner with OBD2 connectivity and following its instructions for reading vehicle data before issuing any commands. Make sure that the computer has been turned on again after connecting the scanner to it.
In order to successfully reset the ECU without disconnecting the battery, you should turn off your car first so there are no new current flowing through the system when performing a code scan. Make sure everything has been plugged in properly before proceeding with code scanning and finally issuing a command to reset your computer system. After completing these steps, you should always restart your car so everything reverts back to normal.
