Problem:
Toyota BB 2012 Twist Knob system is supposed to be 4D, I tried Xhorse VVDI Key Tool Plus, Autel and Xpad and can’t be done by obd2. I take out the immo box and read eeprom 93lc66b but couldn’t open with any option on Key tool plus. Someone has done this job? Which tool or software can do this job?
Solution:
This can’t be done with Key tool plus or VVDI 2.
Put the key in the twist knob, short the ODB pins 4 and 13, and push the twist knob 7 times to force key-on.
After that, put it in registration mode.
Used smart keys cannot be registered without initialization.
To initialize the keyfree ECU, you can use Xtool X100 PAD3 or KPC Pro.
If you enter from Daihatsu with AutoIdol KPC Pro, everything is done via OBD and following the instructions on the tablet will complete the registration.
