Starter kill doesn't work:

Is the correct starter wire being interrupted? If the car starts when the starter kill relay is completely

disconnected, the wrong starter wire has been cut and interrupted.

Are the GREEN and BLACK wires properly oriented? The GREEN goes toward the switch, and the

BLACK towards the starter motor. See page 9.

Starter kill doesn't work only in the VRS

H1/9 YELLOW wire is not connected to true ignition. It is connected to an accessory circuit. See page 10.

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 Final Testing page 21.

Door input does not immediately trigger full alarm. Instead, first I hear chirps for 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 re-closed, 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 page 10.

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 page 10.

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 Diagnostics). 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

Status LED doesn't work.

You've probably guessed already, but here goes: is it plugged in? See page 11. Is the LED plugged into

the correct socket?

Door locks operate backwards.

This unit has easily-reversed lock/unlock outputs. Recheck page 12 to see if you have reversed these.
