Resetting computer...TRUE?

Someone recently told me that instead of just unhooking 1 battery cable, to disconnect both cables, and touch them together for about 10 sec...supposedly resets computer faster? Anyone heard this before?

91 Chevy Beretta 3.1 V-6 Auto

Thanks..

Depends on the system... naturally, you want to be sure that you wont have a power source involved in your battery cable idea. I've used this method before..... much easier is to disconnect the ground and make sure it can't contact the negative post on the battery.... turn on the headlights and go for a pee/cold one/smoke.... Done deal.

Of course, disconnecting both battery terminals is the ideal time to clean those puppies so that they are a shiney lead looking surface.....

Better than clearing the PCM.... fix the problem that makes you do it....

I've heard this is the way to disarm the air bag... don't know about resetting the computer. I thought just disconnecting the battery would do that.

It does't cause any harm, it's just a faster way to "drain any capacitors" that are keeping any memory alive.

Also worth noting that disconnecting the battery will only clear 'soft' codes set in the computer. Hard set codes will remain, and of course, if the problem that set either code still exists, it will show back up the next time you drive.

From the looks of your other threads you problems are not going to corrected from resetting the computer.

So how do you clear the "hard" codes left in computers memory? Is there a way to do it?

Thanks... ~Jen

I think what is meant by hard codes are faults that are present. You clear them but they come back immediately because the fault is present.
