1999-2000 Honda Accord: 'D' Gear Light Blinking Steadily When Engine Starts
My 1999-2000 Honda Accord is showing a blinking steady 'D' light when the engine starts. This indicates a potential transmission issue, and according to the owner's manual, this symptom often points to a stored diagnostic trouble code (DTC). It is recommended to perform a scan of the vehicle's onboard computer system to retrieve specific error codes for accurate diagnosis.
I recommend checking your owner's manual first. A blinking 'D' light during engine start typically indicates a transmission-related issue with a stored diagnostic code. Using an OBD2 scanner to retrieve the exact trouble code is essential for proper troubleshooting.
