Reading Codes
Important: Complete ALL steps in “Vehicle Preparation” before reading trouble
codes.
• Honda uses various computerized engine control systems.
• Trouble codes are read by:
– Observing LED’s (Light Emitting Diodes) built into the engine computer
OR...
– Counting flashes on the “CHECK” engine light.
• Use the chart below to find the code reading test procedure for your vehicle.
Remember: Vehicles using the instrument panel (“CHECK” engine) lamp for reading
trouble codes do NOT require engine computer access.
