how do you reset an ecu in an 87 car?

 

Disconnect the batterie go get a drink come back and connected.

That i believe is the easiest way.

 

Disconnect the battery, and hit the brake pedal for a couple seconds. Reset with no need for a drink, unless it's a beer. You can't work on a RX without a beer...mmmmm. Oh, sorry today is friday, it's on the mind.

 

mmmm beer

 

thanks fellaz....

 

What use is it to push the brakepedal????

 

I believe it is like a reset switch. In fact I (after doing some rewiring TPS troubleshooting etc.) this week did a cpu reset. Actually you just have to remove neg batt terminal then when I pressed brake pedal I had a beep and system reset...cool...

 

I have never heard of that before...

 

All hitting the brakes does is drain the system of any power remaining in the capacitors. It just quickens up the process, but that's still no excuse not to grab a beer while doing it

 

Hitting the brakes wastes time I could be using to drink beer.

 

Bunch of drunkards.

 

You could also pour a Maker's Mark.

 

How would hitting the brakes drain the capacitors as there arent any ground connected from the battery?
