Factory alarm on the Pontiac Grand Prix 1997 & up
The factory anti-theft systems on the new Grand Prix and Grand Prix GTP are user programmable to
have control over various features like horn honk and flashing lights as well as adjusting the alarm
modes and arming and disarming modes. When these vehicles come in to your shop, they may not
be programmed to disarm with the key in the door. This of course will cause a problem as you will
not be able to disarm the factory alarm when remote starting the vehicle. This of course can be
rectified through the user programming, the unit can be reprogrammed to accept a ground pulse from
the wire at the key switch in the door as well as allow arming of the alarm through the driver’s lock
switch before the door is closed.
Programming Alarm modes
1. Pull fuse no.27 ( MALL PGM ) 10amp from instrument panel fuse block. Turn ignition switch to
ACCESSORY position. Ensure that seat belt indicator flashes and chime sounds 2 to 4 times.
Turn parking lights on. As soon as parking lights are turned on, seat belt indicator will flash and
chime will sound the number of times equal to the current mode number.
2. The mode will advance, each time the parking lights are turned on and off. Passing mode 4 will
bring you back to mode 1. To save the new setting, turn ignition switch to OFF and replace fuse.
Alarm modes:
Mode 1: If vehicle is seriously damaged and/or door or liftgate is opened while system is armed, the
alarm will sound and parking lights will flash for up to 2 minutes.
