The LIN bus voltage reads normal with the slave module disconnected, but then reads 0 volt when it is reconnected. What can be the cause?
A) The slave module has an internal short to ground.
B) The circuit between the master and slave modules is open.
C) The circuit between the master and the slave module is shorted to ground.
D) The master module is faulty.

When the LIN bus voltage reads normal with the slave module disconnected but drops to 0 volt upon reconnecting the slave module, it indicates that the slave module likely has an internal short to ground. This causes the voltage to drop to 0 when the module is connected, as the electrical path is being directly shorted to ground through the faulty module.
