Reset How do I reset the computer and engine light?

Repair the antilock brake system first. That should stop the engine light from coming on. If you don't do the repair, no matter how many times you reset the computer, the engine light will come on. Run a diagnostic test to find out what else is wrong. You reset the computer by disconnecting both battery cables, touch them together for a few seconds then reinstall.

reset check engine light disconnect battery for 3 minutes then reconnect this will reset the computer the light will go out.
If the light comes back on their is a problem .

To reset the computer, disconnect the battery for a couple minutes, then hook it back up again. This will not solve the problem if there is one. The check engine light comes on to let you know that there is a problem. If you take it to an auto parts store, they can read the trouble codes and reset the check engine light.

There are three ways to reset a check engine light.

1. Disconnect the battery, wait approximately 30 minutes, reconnect the battery. This resets the cars computer which also reset the check engine light. On newer OBD (on-board diagnostic) compliant vehicles this usually does not work. See step 2.

2. Reset using an OBD II reader. When you hook an OBD II code reader up to your vehicle, you can reset the computer using the code reader.

3. Fixing the problem. Generally the check engine light comes on for a reason. Usually it is emission related (sensors, gas cap) or electrical (faulty wiring). In this case the way to reset the check engine light is to fix the problem

First you must diagnose and repair the fault that caused the check engine light to come on, otherwise, resetting the computer will only result in the light coming back on. Then a scanner must be used to reset the computer memory so that the fault codes are erased.

Reset your computer and the check engine light should go off.How you can reset your computer is take your battery terminal off for 15. min.and then reinstall and should knock the light out.

The light has to be reset using a scan tool or code reader. What you are actually doing to turn off the "check engine" or "service engine soon" lamp is clearing the service codes. Disconnecting the battery cable won't clear the codes on most vehicles built after 1994. You should note what the service code[s] are that caused the computer to turn the light on and have those problems repaired othewise the light will come on again after a few drive cycles once the computer sees that the same problems are still there.

you can use the scanner to clear the computer or even disconnect the battery for a minute or two then reconnect it but if the light comes back it needs to be fixed to keep the light off. just fixing the problem won't turn the light off

The check engine light comes on to alert you that the computer has noted a fault in one of the car's systems. I would take the car to an autoparts store and have them scan the computer for codes stored. Most parts store will do the scan for free. Getting the codes shows what the computer noted so the problem/potential problem can be addressed. Hope this helped and best wishes.

the infomation u were given is 100% wrong! if the light is coming on then a problem exists in the OBD 2 engine control system, there will be a fault code stored for the check engine light, who told u this the dealer??
