Retrieving Codes

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2000 Isuzu VehiCROSS, 2000 Isuzu Trooper, 2000 Isuzu Rodeo, 2000 Isuzu Hombre, and 2000 Isuzu Amigo. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Diagnostic Trouble Codes (DTCs) are retrieved using TECH II or other OBD-II compatible scan tool.
  1. Diagnostic Trouble Code (DTC) retrieval starts with OBD-II diagnostic system check. See ON-BOARD DIAGNOSTIC II (OBD-II) SYSTEM CHECK . Also see SYSTEM WIRING DIAGRAMS article for circuits and terminals referenced in testing.
  2. Turn ignition on. MIL should come on and remain on steady 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 DTC is stored.
  3. If light does not come on with ignition on and engine off, inspect MIL circuit before continuing. If MIL fails to operate, see MALFUNCTION INDICATOR LIGHT (MIL) INOPERATIVE in appropriate SELF-DIAGNOSTICS article.
  4. To retrieve codes, install scan tool. Follow scan tool manufacturer's instruction for DTC retrieval.
