Passlock TM Sensor

The passlock TM sensor is inside the upper right side of the steering column. The passlock TM sensor contains 2 hall effect sensors. The tamper hall effect sensor is on the top. The security hall effect sensor is under the tamper hall effect sensor. Both of the hall effect sensors monitor the magnet of the lock cylinder through an opening. The tamper hall effect sensor is physically placed on top of the security hall effect sensor. The placement enables the tamper hall effect sensor to engage first if an intruder attempts to bypass the passlock TM sensor by placing a large magnet around that area of the steering column. There is a tamper resistor inside the passlock TM sensor in order to help prevent tamper to the system. passlock TM equipped vehicles have a selection of 10 different security resistors ranging up to 13 K ohms. Install any of the security resistors inside the passlock TM sensor in order to generate a unique passlock TM code. All 10 combinations of the passlock TM sensor have the same part number. However, you cannot simply replace the passlock TM sensor and expect the system to operate properly. Always start by performing the Diagnostic System Check first and following the instructions.
