Engine Computer (ECM) Replacement
\015 2000 Pontiac Montana, 3.1L, AT, dual A/C.\015\012\015\012Need to change out faulty ECM.\015\012I have a replacement unit w/ identical numbers (both the SERVICE and HARDWARE nos. are identical matches).\015\012Is this a do-it-yourself 'plug-n-play', or will it require divine intervention by the great Goodwrench god (eg the GM dealer)?\015
As long as HW, Firmware, and memory capacity are identical - it should be a plug and play. Otherwise you may have to swap out a few chips. Any dip switch settings or jumpers on it - check for that.
