To manually retrieve DTCs (trouble codes or error codes), you will need to jumper the OBDII connector.
The OBDII connector is located in front of the center console near the drivers foot well. Jumper pins 4 and 9 together with a small piece of wire or paper clip.
The MIL should start to flash out error codes. To interpret the MIL flashes, count the number of long flashes and multiply by 10, then add the number of short flashes. The resulting DTC code can be referenced in the Honda service manual.
