Open your OBD-II code reader’s manual to the pages that list generic OBD-II codes. Place a bookmark by these pages. Then, go onto the Internet and locate Honda’s supplemental OBD-II codes and print these codes out.
Open the door to the Accord and take a seat behind the steering wheel. Place your coding resources on the front passenger’s seat.
Remove the ashtray from the Accord’s dashboard middle console. The ashtray will be located directly below the radio. In the space revealed, you will find a 16 pin-receiving computer outlet. This is your Accord’s Data Link connector. Connect your code reader’s diagnostic cable to the DLC and turn the device on.
Insert your key into the Accord’s ignition and switch to the on designation. Code Reader brand devices requires that the Accord’s engine be running. If you are using one of these devices, engage the key and start the engine.
Check the code reader’s display screen. Some scanners are preset for automatic code retrieval. Once the reader and the Accord’s OBD-II system sync, the codes may already be waiting for you. If you do not own a device preset in this manner, consult your reader’s manual for command entering instructions. The general layout and operational structure of every brand of code reader is slightly different.
Scroll through the codes on your reader. There are ways you can begin to sort through them, without looking up the definitions. First, look at the status the OBD-II system has assigned each code. A pending designation means the code’s corresponding problem has not happened often. A trouble designation means the problem has happened with a high frequency. Once a code is labeled trouble, the OBD-II system switches on the check engine light.
Look at the first character of each alpha-numeric code. This letter will tell you where the problem is located. P-codes refer to the engine, fueling, and emissions systems. B-codes cover the Accord’s body as well as mechanical components not involved with the engine. C-codes cover the chassis electrical system. U-codes cover network communications.
Make a list on a separate sheet of paper. Group codes together by their status. Always give trouble codes higher priority. Group the codes together by where they are located. In this regard, put all the P-codes together, the B-codes together and so on.
Consult the reference materials you left on the passenger’s seat. Look up a definition for each code. Copy the definition next to its corresponding alpha-numeric code number on your categorized list. Once you have a full hist of diagnoses, consider whether you have the skill and expertise to perform the repairs yourself. If you opt to drive your Accord to a Honda-approved mechanic, take the list with you. It will save you money on the mechanic’s diagnostic fees.
