    • Go to login and type login for basic settings/steering angle adaptation. Then go to basic settings and choose appropriate option.
  • If login that you calculated from PR codes doesn’t work, try different brake type number.
    • If it will work for login, you might need to use the same brake type for coding (otherwise it might not accept it).
• Long Coding
  • 2009 VW Jetta Long Coding

• Buckle Testing | MKIV

  • There are two resistors in the buckle switch: 470 Ohms and 1.1-1.2 kΩ
  • 2 wire type
    • there are 2 pairs of pins at the plug
    • Try using 470 Ohms to emulate buckled state between YEL & BLUE wires
  • 4 wire type
    • one pair is connected and the other is open when the belt is unbuckled
    • one pair is open (GRN & BRN) and the other shows a resistance value (YEL & BLUE) when the belt is buckled
    • the way to do this is to identify which pair is which and insert a resistor across the correct pair
    • Try using 470 Ohms to emulate buckled state between YEL & BLUE wires
