WARNING: This page is about a different car, the 2005 Acura NSX, 2004 Acura NSX, 2003 Acura NSX, and 2002 Acura NSX. However, it is still accessible from the selected car via links, so may be relevant.
When the Malfunction Indicator Lamp (MIL) has been reported on, this indicates a Diagnostic Trouble Code (DTC) is stored in the ECM memory. See RETRIEVING DIAGNOSTIC TROUBLE CODES .
If ECM has been replaced as part of a diagnostic or repair procedure, the immobilizer code will need to be rewritten. See IMMOBILIZER SYSTEM .
