Radio Diagnostic mode on radio

Bungle · 22nd November 2006, 08:13

Inspired by Pottsy's post here Radio problems on the radio reception thread, I found some other neat little feature I thought I'd share.

From the mentioned diagnostic menu, (pressing and holding 1,6,power, then realeasing) you can do a few things.

As is Pottsy's post, holding [fm] for a few seconds brings up the signal strength. You can change station by pressing [>>|] or [|<<] and change the volume.

Pressing 3 toggles a display check where every segment lights up (there are loads!) and goes out with another press.
pressing 4 confuses me, it shows something like 00, 000 22 (I think). I have no idea what this does, and as far as I can tell, the nuber 22 does not change. I will leave this well alone.
Now this is the really interesting one. Press 5 wil bring up "vsp 000".

I have deduced the 'vsp' means vehicle speed, and the numbers change as you drive the car. At first I wasn't sure what it was displaying, then I realised that it shows the TRUE speed (in kph) before the speedo adds a bit to make it over read! The speeedo has to be changed to kph to make it make a little more sense. The speed reading is a little jumpy, but I am positive is far more accurate, always reading a speed a few kph below the speed on the speedo. I have not tied this with a GPS to compare yet.

I can only assume this is in the radio diagnostic menu because it has speed sensitive volume.

Anyway, I thought you guys would like to play with this. As far as I can tell, it is only for viewing information, and nothing can be changed, but do take care.

Bungle - the strange numbers are for the engineers to calibrate the brightness of the LCD. The 22 part is controlled by the brightness knob on the dash and goes from 22 (full bright) down to 0 (off). The 4 digits on the left go the other way round and are connected to the actual brightness of the LCD.

I didn't know the VSP digits are actually kph, they are however directly connected to the vehicle speed impulse generator.

I found this at lunch time as was going to do a post and someone beat me to it

I figured it might be the direct feed from the speed sensor, or "vehicle speed impulse generator" as you so nicely put it. It does seem to jump around a bit, but I am still fairly certain that it is more accurate than the main speedo. It's frustrating the the (large) error introduced to keep Honda safe is actually visable now.
There must be software that stabalises the speed reading and increases it slightly. I wish I could change that so 30mph is 30mph, not 27 or so.

Come on Pottsy, find us more menus with you random button bashing!

Sadly there aren't any (it's not actually random button pressing I'm doing), but if you had an HDS machine then all sorts of interesting options would be there for you.

what speed is the speedo out does your gps read , think it was tt regs mimes about 4 mph sometimes 3 , think its safer to levae the speedo out so you have less chance of been done by camers all speedo are some out ,
307-405 and celica are all 3-4 over and 944 is 2 mph out and combi vans even 5 out. if you like me once you know how far it out you travel at the right speed. but i still do the 4 under going thought camers just to make sure

the speedo level of error seems to vary by speed.

At an indicated 33, true speed seems to be 30 GPS

but at an indicated 75, true speed is 70 GPS

80 (noted very briefly!) indicated was pretty accurate - 77 GPS

But that's in MY car - please don't take it as true for ALL Civics, and don't blame me if you get a ticket!

Mine is more accurate the faster it goes. The difference is >10% at low speed, and much better at motorway speeds. Odd.

Another thread brought back from the dead by me today

I did the 1,6,PWR button press earlier today.
I did it on my car (no sat nav).
Here's a few pics of a few of the menu's I could get up.
Couldn't get any of the numbers to change though??

Anyone care to explain what some of them mean and what can I change?
