Troubleshooting
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.
➤
YELLOW wire is not connected to true ignition. It is connected to an accessory circuit.
Shock sensor doesn’t trigger the alarm.
➤
Has the NPC
®®
system been triggered? If so, you will hear five chirps when disarming. To check
this, turn the ignition key on and off to clear the NPC
®®
from memory, and then retest the
shock sensor. For a detailed description of NPC
®®
, see Owner’s Guide.
Door input does not immediately trigger full alarm. Instead, I hear chirps for the first three seconds.
➤
That’s how the progressive two-stage door input works! This is the instant response feature of
this system. Even if the door is closed immediately, the system provides an instant trigger by
chirping, and the progressing to a constant siren.
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.
IMPORTANT: When testing the systems sensor and trigger inputs reset NPC by
turning on the ignition after every third system trigger.
