MIL Stays On

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.
- If this symptom is intermittent, check for:
- A loose ACG(S) (20 A) fuse in the engine compartment fuse/relay box
- A loose No. 2 FUEL PUMP SRS2 (15 A) fuse in the under-dash fuse box
- An intermittent short in the wire between the ECM (C5) and the service check connector
- An intermittent open in the wires between the ECM (A26, B14) and the service check connector
- An intermittent short in the wire between the ECM (A7) and the gauge assembly
- An intermittent short in the wire between the ECM (F1) and the MAP sensor, accelerator position sensor
- An intermittent short in the wire between the ECM (D10) and the TP sensor, EGR valve lift sensor
- An intermittent short in the wire between the ECM (F14) and accelerator position sensor
- See the OBD II scan tool or Honda PGM Tester user's manuals for specific operating instructions.
