Retrieving Codes

WARNING: This page is about a different car, the 1996 Acura SLX. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Codes can be retrieved using a scan tester. Trouble codes are referred to as DTCs.
  1. Code retrieval starts with diagnostic circuit check. See ON-BOARD DIAGNOSTIC II (OBD-II) SYSTEM CHECK  . MIL will come on when ignition is on and engine is not running. When engine is started, MIL should go off. If light remains on while engine is running, a trouble code is present.
  2. If light does not come on with ignition on and engine off, inspect MIL circuit before continuing. If MIL fails to operate, see ON-BOARD DIAGNOSTIC II (OBD-II) SYSTEM CHECK  .
  3. To retrieve codes, install scan tool. Select MIL dash lamp control and command the MIL OFF. Ensure MIL light is off and attempt to start engine. If vehicle does not start, go to vehicle NO-START tests.
