alarm troubleshooting

■ 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.
