■
Shock sensor doesn't trigger the alarm:
Has the NPC® system been triggered? If so, you will hear 5 chirps when disarming. To check this,
turn the ignition key on and off to clear the NPC®'s memory, and then retest the shock sensor. For
a detailed description of NPC®, see
Nuisance Prevention Circuitry
section of this guide.
■
Door input does not immediately trigger full alarm. Instead, chirps are heard for the first 3
seconds:
That's how the progressive two-stage door input works! This is a feature of this system. This is an
instant trigger, remember, since even if the door is instantly closed again, the progression from chirps
to constant siren will continue.
■
Closing the door triggers the system, but opening the door does not:
Have you correctly identified the type of door switch system? This happens often when the wrong
door input has been used. (See
Door Lock Harness Wire Connection Guide
section of this guide.)
■
System will not passively arm until it is remotely armed and then disarmed:
Are the door inputs connected? Is the H1/6 blue wire connected to the door trigger wire in the
vehicle? Either the H1/5 green or the H1/7 violet should be used instead. (See wiring diagrams.)
■
Door input does not respond with the progressive trigger, but with immediate full alarm:
Does the Status LED indicate that the trigger was caused by the shock sensor? (See
Diagnos-
tics
section of this guide.) The shock sensor, if set to extreme sensitivity, may be detecting the
door unlatching before the door switch sends its signal. Reducing the sensitivity can solve this
problem.
■
The Valet/Program switch doesn't work.
Is it plugged into the correct socket? See
Plug-In LED and Valet/Program Switch
section of this
guide.
■
Status LED doesn't work.
You've probably guessed already, but here goes: Is it plugged in? (See
Plug-In LED and Valet/Program
Switch
section of this guide.) Is the LED plugged into the correct socket?
■
Door locks operate backwards.
This unit has easily-reversed lock/unlock outputs. Recheck wire connections to see if you have
reversed these.
