Welcome to JustAnswer. Please give me a few minutes to look over the wiring and radio information.

Be right back, Honda-Man

Expert:  Honda-Man replied 1 year ago.

Just to be sure, did you check fuse #8 in the driver's under-dash fuse box, fuse #9 and #11 in the passengers under-dash fuse box? Can you pleas tell me if the power outlet socket works?

Customer: replied 1 year ago.
Power outlet socket works. All other power in van works. Checked all fuses including ones mentioned.
Expert:  Honda-Man replied 1 year ago.

Thanks for the reply and information. The power outlet relay also supplies power to the radio that's why I asked if it worked. If the fuses are OK and the radio ground is also OK the radio will need to be removed to test the wiring. I have included a picture of the radio ground wire location near the scan tool connector. If the wiring tests good you must have gotten a bad radio. The only way to be sure is test the radio connector for power and ground. I can help you with the test instructions if needed.

Just to confirm that I checked the right fuses, which one is #39 under the hood? I checked al 7.5,10,15 and 20amp fuses
Expert:  Honda-Man replied 1 year ago.

#39 is not a good fuse number for the under hood fuse box. the lowest number is #41. I have included diagrams with the fuse locations for the drivers side under dash and passengers side under dash.

Thanks again, Honda-Man

Expert:  Honda-Man replied 1 year ago.

None of the fuses under the hood would cause the radio to fail. If one under the hood was blown other electrical items would not work.

Did you supply a picture of the radio ground wire location?
I dont see it anywhere. I will test the radio now
Expert:  Honda-Man replied 1 year ago.

Sorry got the picture ready but forgot to send it.

Customer: replied 1 year ago.
Okay. Im a bit confused. Where is the exact location of this picture? Am I going into the radio, under the hood or inside where the radio is located?
Customer: replied 1 year ago.
Sorry but can u resend last message? Got deleted somehow
Expert:  Honda-Man replied 1 year ago.

Sorry for the delay.It's under the dashboard near the OBD2 connector passenger side under the glove box.
