Hey whats up guys..my ECU just came in..its a 2001 LS ECU..and yes i know it has an immobilizer....but i have that covered...i unplugged my EX ecu and plugged up the integra ECU...i was just checking to see if everything plugged up ok..sure enough everything plugged up..i turned the ignition to see if the immobilizer was doing its job..and sure enough it did.....soo i replugged the old EX ecu back up...turned the car on.....but now i have a CEL...why did that come up..and is it safe to drive the car?

What code is the ex ecu throwing?

you will need to know the code it is throwing to determine whether it's a hard code (throwing the ecu into safe mode) or a soft code.

i just reset the battery.....and let the car idle for 10 min....no light...so is everything ok?

yeah, if you get the CEL you will need to check it once again.

Sohc Driver

if it was a hard CEL..resetting the battery wouldn't have fixed the problem would it?? so any ideas as to why the CEL came on with what i did?

if you reset the ecu, and the light does not come on, it's most likely not a hard code.

a hard code will throw the ecu into safe mode because the ecu thinks that whatever sensor/solenoid is not working may cause the engine to blow/cease.

a soft code will not affect much on the motor from allowing to run properly, and in resetting the ecu, and not throwing cel, it was most likely a soft code that you will not need to worry about; unless, of course, if it pops back up.

unfortunately, i have no idea of as to what the code you were throwing.

oh yeah..i failed to mention..that i had the key in the ignition..when i replugged my old ECU back up...did that have anything to do with it?

Khoi

nope. it does not.

the cel comes on for about 1 second then turns off, that is completely normal.

Sohc Driver

but i meant..i had the key in..while i was replugging the old ECU.......know what i mean..the igntion was on....while i was doing it...maybe when i was pluggin in the ECU..it freaked out....noticing that a plug was missing..because when i plugged in the 2nd plug..everything electronic turned on...im thinking..the ECU freaked out...
