how to clear computer codes ?
guys, i have a 1990 k1500 with 5.7 v-8.
to clear all check engine light codes, is it enough to just remove the positive battery cable for a few minutes, then reconnect ?
i just ready online someone suggest pulling both battery cables, then turning on the inside interior light, to discharge all stored power, then reconnect.
is all the really necessary ?
