How to generate a CAN Bus-Off Condition?

I am connecting my MC9S12DG128 based board to the Vector CANalyzer to check my CAN transmission.
If I stop receiving the frames on the CANalyzer, then registers in the microcontroller, indicate that an "Error Passive" state has been reached.
The problem I am facing is - Using this setup, I am unable to generate a Bus-Off Condition. The CAN controller in the microcontroller gets stuck at the Error Passive state, when I stop receiving the frames.
 
Any inputs why this happens and how do I generate a Bus-Off condition?
