The first thing I check with that code is the oil level. Low oil presure caused by low oil level is a common cause.

to reset the ECU remove the "back up" fuse for like 10 seconds, or disconnect your negative battery terminal for a minute or two, OR disconnect your ECU

do NOT disconnect the ECU with the battery still connected.
there is a constant supply of voltage to the ECU and when removing the harness, it could easily jump to another pin on the ECU and cause serious damage. i have seen it happen before.

what about when people remove their ECU from their cars as a anti-theft device?

they risk shorting the ECU every time they remove it.

im not saying it happens every time you pull the plug on it, but you run the CHANCE of it arcing to another pin and frying the circut.

They should disconnect their battery first.
