my merc had been changed the indticator consloe jus a few days ago, then the mechanic told me the srs lamp came on, he told me that he kept scanner in and came up with the faulty codes:4 AIRBAG IGN.CKT.DRV CODING FAULTY. and 1 CONTROL MODULE N2/2..he doesnt have a proper scanner but where we are in kenya eldoret its pretty alrite for what he does. is there any way of resting it manuly. or does it need a m/b scanner?

thank you
