at a 10% duty cycle. The system can only be disarmed with a programmed key fob.
When the alarm is tripped, the park lamps and the horn will flash indicating that the vehicle has been tampered with. The alarm can be tripped by
opening doors, hood, liftglass (coupe) or turning the ignition on. Once tripped, the alarm will sound for 2.5 minutes. The park and tail lamps will
flash for approximately 18 minutes. The PCM will not allow the engine to start. If the EM has been tripped and 18 minutes have passed, the horn
will chirp 3 times upon unlocking with the key fob to alert the driver that a theft condition may have taken place. Normal disarming with the key
fob will result in two sort horn chirps.
(98 ONLY)
The security portion of the module performs typical security functions. The system can be actively armed by pressing the lock button on the key
fob. The system responds with a single horn chirp, if the message is from a valid (programmed) key fob. This information can also be accessed on
the VTSS monitor screen with the DRBIII. The system will passively arm if the ignition is turned oft and the key is removed, the hood and lift
glass (coupe) are closed, and while a door is open, the door lock button is pressed. The system will arm immediately upon door closure. There will
be no horn chirp.
The security LED will then flash at a 10% duty cycle. The system can be disarmed with a programmed key fob or by inserting the VTSS disarm
key in the disarm switch. This switch is located in the storage cubby box, when turning the key the system is disarmed. It can only be used to
disarm the VTSS, not to arm the system. When the alarm is tripped, the park lamps and the horn will flash indicating that the vehicle has been
tampered with. The alarm can be tripped by opening doors, hood, liftglass (coupe) or turning the ignition on. Once tripped, the alarm will sound
for 2.5 minutes. The park and tail lamps will flash for approximately 18 minutes. The PCM will not allow the engine to start. If the EM has been
tripped and 18 minutes have passed, the horn will chirp 3 times upon unlocking with the key fob to alert the driver that a theft condition may have
taken place. Normal disarming with the key fob will result in no horn chirps, but will flash the park and tail lamps.
Diagnostics
The EM system is fully addressable with DRBIII and it is the recommended method for diagnosis. The EM system does not display any Diagnostic
Trouble Codes. All of the input switches to the EM can be read with DRB under the I/O screen. The doors can be unlatched with the DRB under
actuator tests. If the inputs are OK and the outputs can be cycled with the DRB, the problem is usually the Entry Module.
