Yaris mk1 cd/radio audio system not working after battery removed

[Gpav6]

So I had to reset my ecu after having the engine management light on due to a bar maf sensor which i then replaced and reset the ecu by removing the positive wire that goes to the battery. I removed this for 10 mins after which everything reset including the ecu, job done i thought until now.
I now cannot do nothing with the radio or cd player, although i can change station it does not work, even when i press steering wheel buttons i cannot change volume , there is no volume.
Even when i press eject on the cd player it does not reel it in.
Prior to this everything was working.
Is this a code issue or has the fuse blown?

Edit: its a yaris mk1 2003 t-spirit eith a standard toyota cd / radio system

The MK1 radios did not have a security code, so check the ACC and DOME fuses.

Any idea how to check and fix this?

DOME is a 15A fuse. Very strange that it is missing.

Turns out it is the h-ip main 20a fuse that was missing.
I checked amp and dome and both are ok.
Cd/radio still not working

That makes more sense. Have you tried disconnecting the radio or pulling the dome and ACC fuses for a couple of minutes to try rebooting it again?

Ok thanks for that , i tried taking the fuses out and I even replaced dome fuse but nothing has changed. I will try disconnecting radio tommorrow.
Any other ideas?

Beyond that, I'd say that the radio must have an internal problem that occurred during the battery replacement.

Ok I took the cdplayer out and it seems to be a faulty cable at the back, some times when you wiggle it , it works and other times it doesn't.

Look a the pins on the connector to see if they are deformed where the holes are too large. If so, you can reshape them with a tiny screwdriver.
