NOTE: For circuit and connector terminal identification, see CONNECTOR IDENTIFICATION . For wiring diagrams, see WIRING DIAGRAM  section.
  1. Disconnect fuel pump and Oxygen Sensor (O2S) connectors. Using scan tool, check resistance of ASD relay connector Dark Green/Orange wire. If resistance is less than 5 ohms, go to step 3).
  2. If resistance is more than 5 ohms, check resistance of O2S connector (component side) relay output circuit (White wire). If resistance is less than 5 ohms, replace O2S. Perform TEST VER-1. If resistance is more than 5 ohms, replace fuel pump. Perform TEST VER-1.
  3. Disconnect ignition coil connector. Using scan tool, check resistance of ASD relay connector terminal "D" (Dark Green/Orange wire). If resistance is more than 5 ohms, replace ignition coil. Perform TEST VER-1.
  4. If resistance is less than 5 ohms, disconnect fuel injector harness connector. Using scan tool, check resistance of ASD relay connector terminal "D" (Dark Green/Orange wire).
  5. If resistance is more than 5 ohms, repair short to ground in fuel injector harness. Perform TEST VER-1. If resistance is less than 5 ohms, repair short to ground in Dark Green/Orange wire between ASD relay connector and fuel injector harness. Perform TEST VER-1.
