Is N-1 OK indicated?

YES -Do the indicator drive circuit check (see SELF-DIAGNOSTIC FUNCTION ). If the indicator does not go off; replace the gauge control module (see GAUGE CONTROL MODULE REPLACEMENT ).

NO -Substitute a known-good immobilizer-keyless control unit, then register it and recheck. If the symptom goes away, replace the original immobilizer-keyless control unit (see IMMOBILIZER-KEYLESS CONTROL UNIT REPLACEMENT ).
