Hello all DKers
i was bored today so i had a play around with a 2009 toyota corolla radio i had with unknown 3 digit code.
powering it up showed 'SEC'
Inside was TSSOP8 L01A make by Rhom
After a while i found:
Code is stored in address $04-$06 (number is repeated ie 11 22 33)
You can remove the code totally by changing address $14-$17 to FF
Once stereo is unlocked, you can enter your own code by:
turn unit off still with both BATT and ACC connected
hold, 1 + 6 + PWR for 5seconds
SEC comes up
Press seek up + 1
- - - is displayed
Enter code (i entered 123)
Press and hold scan
Unit turns off
This now programs unit to code entered.
Hope this helps someone
Cheers!
