NOTE:
- When there is no Diagnostic Trouble Code (DTC) stored, the MIL will stay on if the SCS service connector is connected and the ignition switch is ON (II).
- If this symptom is intermittent, check for:
- A loose ECU (ECM) (15 A) fuse in the under-hood fuse/relay box
- A loose No.2 FUEL PUMP fuse (15 A) in the under-dash fuse/relay box
- An intermittent short in the wire between the ECM (C7) and the service check connector
- An intermittent short in the wire between the ECM (A18) and the gauge assembly
- An intermittent short in the wire between the ECM (D4) and the MAP sensor
- An intermittent short in the wire between the ECM (D10), the TP sensor, EGR valve lift sensor and/or Fuel tank pressure sensor
- An intermittent open in the wire between the ECM (A9, A22) and G101
- PGM-FI main relay.
- See the OBD-II scan tool or Honda PGM Tester user's manuals for specific operating instructions.
