Jeep 2018 GRAND CHEROKEE, User Manual

Page: 23 / 372

Irregular Operation
The system uses a key fob, an Ignition Node
Module, Keyless Push Button Ignition and a
RF receiver to prevent unauthorized vehicle
operation. Therefore, only key fobs that are
programmed to the vehicle can be used to
start and operate the vehicle. The system will
not allow the engine to crank if an invalid key
fob is used to start and operate the vehicle.
The system will shut the engine off in two
seconds if an invalid key fob is used to start
the engine.
NOTE:
A key fob that has not been programmed is
also considered an invalid key.
During normal operation, after placing the
keyless ignition in the ON/RUN mode, the
Vehicle Security Light will turn on for three
seconds for a bulb check. If the light remains
on after the bulb check, it indicates that
there is a problem with the electronics. In
addition, if the light begins to flash after the
bulb check, it indicates that someone used
an invalid key fob to try to start the engine.
Either of these conditions will result in the
engine being shut off after two seconds.
If the Vehicle Security Light turns on during
normal vehicle operation (vehicle running for
longer than 10 seconds), it indicates that
there is a fault in the electronics. Should this
occur, have the vehicle serviced as soon as
possible by an authorized dealer.
