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.
Starter kill doesn't work only in the VRS
®
mode:
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 re-test 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? I(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
®
/Program switch doesn't work.
Is it plugged into the correct socket? See page 11.
VRS
®
feature doesn't work.
Did you install the switch in the right socket? Did you enable the feature? Did you read the Owner's
Guide for operation of this VRS
®
feature? (It differs from the outboard 540T VRS
®
system). See page
22. Are you arming the VRS
®
with the door closed?
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.
