Hi,My name is XXXXX XXXXX I'm an expert here at JustAnswer.com. I'd be glad to help you out with this problem.
Ok. What are your thoughts?
Let's make it easier for me. What isn't working right now?
Dash lights, radio, brake lights?
correct. Also had the "key reminder chime" malfunction a day or two ago, but that seems to work now
Okay check the fuse #10(15A) in the pass. interior fusebox
all the fuses checked out fine
Recheck that fuse for me
It controls the audio, brake light relay and dash lights
Also fuse #9 (10A) in the driver's interior fusebox.
Also, the 12v constant to the radio does not register any voltage
Usually the coins short the circuit and blow a fuse. It's actually quite common for kids to put the coins in the CD slot. I get 1-2 a month
Just double check those 2 fuses for me.
I don't have the car available to me right now. But I did test all of the fuses with a multimeter this morning and they were all fine. If it isn't a fuse, any other suspects?
It's a fuse. Don't use a meter on the two I told you to check. Pull them out. Sometimes fuses break in the legs and you will show voltage in the fuse when it's actually blown.
It's rare but you could have damaged a multiplex control unit
I doubt it though
I think fuse for sure
I see it way too much.
Want to wait until you have the van and let me know?
That would be great. If my wife can't get it fixed, should there be any issues with her driving 100 miles tomorrow to get home?
I wouldn't drive without brake lights. Too risky. I'm sure it's a fuse though. Have her pull those actual fuses and check them. One is blown.
OK. So do I click on "save and exit" and I can still accept your response tomorrow or follow up if I need more assistance?
Yes. You can accept tomorrow and follow up and even if you accept you can still follow up so don't worry about that. I'm here if you need to go further with it.
Awesome, thanks. Glad to hear that its not uncommon.
no problem see you soon
The #10 was blown and when replaced the rear running lights now work (and probably the dash lights but its too bright for her to check). Radio still doesn't work. I had her check #9 and 11 of the passenger, as well as #8 of the drivers side and all looked intact (these are all referenced on the Haynes diagram for the sound system).
Couple questions about the radio:
1) is it likely that the coins could have fried something to make the radio non-functional
2) does the radio require a 12v constant to function? My understanding is that the 12v constant to the radio is just to keep radio presets etc when the car is turned off. My hunch is that even without a 12v constant, the radio should turn on when I turn the key, but I would just need to put in the security code every time I start the car (just like if I disconnected the negative lead from the battery).
If it is relevant, my odyssey has a rear entertainment system
The radio can short out internally. In the past I've had a couple where the coin actually melts or welds itself to the pins on the circuit board. It's hard to explain but where the harness pulls into the back on the other side of that the pins go into the radio then bend 90 degrees and are soldered to the circuit board. That bend is where coins seem to do the melt/weld/stick to the pins. You'll have to pull the radio and carefully take off the top metal cover and look inside.
I'm totally sure about the constant. I'm thinking the main power is on the IGN + and you're correct about the constant being for things like the presets or on some cars the ANT, etc.
