Has the NPC® system been triggered? If so, you will hear 5 chirps when disarming. To check this, turn the igni-
tion 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.

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.

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.)

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.)

Does the Status LED indicate that the trigger was caused by the shock sensor? (See Diagnostics 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.

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?

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

1. Check the harnesses and their connections. Make sure that the harnesses are completely plugged into the
remote start module. Make sure there are good connections to the vehicle wiring.
