Immobilizer
SeeRadio Frequency Statement 0349.
Immobilizer Operation
This vehicle has a passive
theft-deterrent system.
The system does not have to be
manually armed or disarmed.
The vehicle is automatically
immobilized when the vehicle is
turned off.
The immobilization system is
disarmed when the ignition is on or in
ACC/ACCESSORY and a valid
transmitter is in the vehicle.
The security light in the instrument
cluster comes on if there is a problem
with arming or disarming the
theft-deterrent system. The system has one or more RKE
transmitters matched to an
immobilizer control unit in your
vehicle. Only a correctly matched RKE
transmitter will start the vehicle.
If the transmitter is ever damaged,
you may not be able to start your
vehicle.
When trying to start the vehicle, the
security light may come on briefly
when the ignition is turned on.
If the engine does not start and the
security light stays on, there is a
problem with the system. Turn the
ignition off and try again.
If the vehicle will not change ignition
modes (ACC/ACCESSORY, on, off), and
the RKE transmitter appears to be
undamaged, try another transmitter.
Or, you may try placing the
transmitter in the transmitter pocket
in the center console.
If the ignition modes will not change
with the other transmitter, or with the
transmitter in the transmitter pocket,
your vehicle needs service. If the
ignition does change modes, the first
transmitter may be faulty. See yourdealer who can service the
theft-deterrent system and have a new
RKE transmitter programmed to the
vehicle.
It is possible for the immobilizer
system to learn new or replacement
RKE transmitters. Up to eight
transmitters can be programmed for
the vehicle. To program additional
transmitters, see
“Programming
Transmitters to the Vehicle ”under
Remote Keyless Entry (RKE) System
Operation 027.
Do not leave the transmitter or device
that disarms or deactivates the
theft-deterrent system in the vehicle.
