The optional Meritor keyless security system is a complete vehicle security system. If installed, it locks and unlocks the doors, protects against theft, and provides security for the driver while sleeping or resting inside the vehicle.

The system consists of the following components:

  • A hand-held radio frequency transmitter that looks like a key chain fob. It acts as a remote control for locking the doors, unlocking the doors, or placing the system on alert. Each system allows as many as four different fobs. See Fig..

    3. UNLOCK Button

  • A red system-status LED (light-emitting diode) mounted on the overhead panel above the clock. The LED flashes slow or fast to indicate what state the system is in: armed, alert, alarmed, or violated. It is off when the system is disarmed. See Fig..

  • A Meritor relay module mounted behind the right-hand B-pillar electrical compartment door that arms and disarms the system and programs the fobs.

  • A program switch on the Meritor relay module that places the relay module in the learning mode, which is the only state in which the system can learn fob ID codes. The switch is shown in its normal, or OFF, state (toggle pointing up). See Fig..

  • A security system electronic control module (ECM), also mounted behind the right-hand B-pillar electrical compartment door, that monitors all the entry points, controls the door locks, operates the alarm, and interrupts the power to the engine, as necessary. There is also a PDM (power distribution module) relay module mounted on top of the left-hand side of the ECM.
