The Passlockâ„¢ lock cylinder is a locking cylinder that turns a rotating magnet past a stationary hall effect sensor. The rotating magnet creates a resistance code (R-Code) that the cylinder sends to the instrument cluster. The Passlockâ„¢ lock cylinder interfaces with the instrument cluster through a 3 wire connection. The 3 wires have the following functions:
| • | Power |
| • | Ground |
| • | Data |
