how do i reset my cars computer? it cut all power. i have 96 range rover. please help?

Answer 1

Disconnecting the battery for most vehicles for a period of a minimum of 5 minutes will do it however some models its advisable to go a little longer

Hence on a Range Rover I'ld recommend 30 minutes before you hook it back up...

also be aware various types of vehicles have varying lengths of computer relearn processes....

i.e. 1992 Ford Ranger is 20 minutes after full operating temp is reached.... for others it can take 40-60 key cycles etc...

Warning ....During relearn process vehicles performance will be less and its response will be a little sluggish do not take any chances until you are sure its relearn is completlely done

Answer 2

Disconnect the battery. This will reset the cars computer settings to the factory specs. Reconnect and drive away.

Answer 3

Computers don't "cut all power" as you say.

They can however disable the fuel system, and ignition system.

If you have no electrical operations, I'd guess you have a dead battery, or faulty connection.

Answer 4

first i would like to let u know that ecu(electronic control unit)doesn't cause a cutting of all power,ecu error or faulty may be resulted as an ignition failure or car cutt out problem.
if all power is gone,check ur battery cables,and check ur battery it self.
good luck.

Answer 5

is not the computer ,is one of the accidents sensors.sort of the gas cut-out in the trunk for instances

check computer grounds(ground wiring),some times does the same.
