Mitsubishi Outlander: Wireless Control Module (WCM)
General Information
The wireless control module (WCM) is a system that
integrates the keyless entry function, with which
remote operation (opening/closing of all doors and
the liftgate and operation of warning function that
warns a person who intends to damage the vehicle
*), can be performed by operating the lock/unlock
button or panic button on the ignition key (transmitter).
Also, WCM incorporates the immobilizer function,
which prohibits the starting of engine using an
unauthorized key, and the tire pressure monitoring
system (TPMS), which issues a warning to a driver
by illuminating or flashing the warning light if an
abnormality to the tire pressure is detected. WCM
has the following features:
- The ignition key has an indicator light that
enables the driver to check if the signal is transmitted
correctly or if the battery in the key is discharged.
- Each vehicle is provided with two ignition keys,
and up to eight ignition keys can be registered.
- Settings of the keyless entry function can be
adjusted using a customization function.
NOTE: *: Horn sounds, and headlights and taillights
flash.
