Disconnect the battery for a few minutes. or try this PRESS: OFF & WARM (red button) together - the D.I.C. will light up the instrument cluster like a Christmas tree - the D.I.C. will start diagnostics, as soon as it starts displaying .. PRESS: LO - until " ECM " comes up PRESS: HI - until " CLEAR CODES ? " comes up PRESS: HI - press only once - response will be in a few seconds: CODES CLEARED you are done ... PRESS RESET and you are back to normal
