Exclamation Question Help after ecu rest?!?!?!?

Here is my question. Just installed cobb intake. I have 2x checked all connections. I disconnected neg batter terminal for 45 minutes. When reconnecting the emergency lights or corner lights flashed. I thought ok since I have never reset the ecu before this may be normal. But now car has been idling for 10 minutes and the lights are still flashing. No the blinker switch is off i checked that. When the lights flash the clock lights up brighter along with the dash illumination. And no the lights on the car are off as well-- I tried cycling the headlights-- no go. Tried pressing hazard switch on and off couple of times. Still doing same thing. Also i did not blip throttle either.

Is this normal until I turn the car back off? I do not have alarm sys so it is not that.I am going to let car run for another 10 15 minutes then shut it off and turn back on. Just curiuos as to if the lights flashing are normal during this procedure. Only other mod is stromung muffler but that has been on car for 6 months now. Nothing else was done but install the cobb intake.

2000 BRP 2.5 rs

Any help or info on this would be greatly appreciated.


Thanks,


Mike G


Ps. I went back out and watched it more closely. The lights will blink for about 2 minutes then stop for 30 then start back up again. Also still no check engine light.

Pss. Turned off car and let sit for 5 minutes. Lights still blinking even with keys out of ignition. Started car back up and the lights are still blinking. Please I need some help. Right now I went on ahead and checked all fuses.. They are all good both under hood and under dash. I have now pulled both pos and neg leads off battery and will let it sit for about 30 45 min and reconnect to see what happens.

Err, you may not have a siren, but I think you do have the remnants of an alarm there. The lights will flash in exactly the way you describe, and the stock alarm will go off when power has been restored.

I thought the alarm was stock on all models? Did you try to remove it?

Lock or unlock your door . If you have keyless entry you just need to hit the 'clicker'.

Thanks. I just logged back on to say i figured it out after reading from page one in the manual till i got to the part about keyless entry and disconnecting the battery. Thanks for the help. It is about to storm bad here hopefully it will holf off for about another hour so i can test out the intake.

I would have never imagined the keyless entry sys would cause this. Writing i permamnent mental note for next time. Should be in about 2 weeks I should have headers in. Already have midpipe but it is just not installed-- will install in a week once I am sure everything is working fine.

Thanks

Question ECU Reset

Rather than start a new post on the same topic, I figured that I would ressurect this one from the dead.

Saturday I removed the intake silencer on my 98 GT and did an ECU reset (disconnect battery etc...) Upon hooking it back up, I too had the blinking light syndrome mentioned above. Unfortunately I had to remove my power locks fuse for a quick fix.
Here's my problem...my car apparently has a remote keyless entry receiver on it. Found that while pulling the fuse, however, I do not have a "clicker". I bought the car last year (used at a dealer) and have never had a keyless entry remote for the car.

Any suggestions? I figured that I'd take it to the dealer to get it cleared up if no one here can help.

Thanks and long live the dead posts.

Peace,
Oqui

on the impreza you turn the key to the on position and press the keyless programming button that is located under the dash for 1 second and it sets the keyless system. This will stop the lights from flashing. There is probably a little black button under your dash panel as well because I think most of the keyless systems are the same.

Default Another way to reset ECU

Try this self-diagnostic code clearing procedure without disconnecting the negative battery cable:

Warm engine to operating temperature.
Turn off car.
Look under steering column, there should be black male/female (read memory) connectors and green male/female (test) connectors. Might be taped together so look hard.
Connect greens together and blacks together.
Turn ignition on without letting engine start.
You'll hear the radiator fans and faintly hear the fuel running in the back.
Depress the gas pedal fully for 2 seconds and then half way for 2 seconds.
Turn the engine on and rev it up WOT for 2 seconds.
Drive it hard for at least one minute (CEL should be blinking while you drive)
Turn the car off.
Disconnect connectors.

When you start the car again, the CEL should'nt pop up. It worked for me.

This seems like the same as this link from MRT?

Thanks for the replies!

I had read about the alternative ECU process (MRT) and tried it, however the black wires are apparently of a different sexual persuasion as they are both female connectors.

I'll have to try to find this button under my dash at lunch. Is there somewhere specific I should look for this?

Thanks again.

this link has the installation stuff for the legacy keyless entry. There should be a little black button under the dash or by the wire harness system for the keyless entry. With the key turned to the on position just press the button for a second and the lights will stop flashing.
