SOLUTION
See procedure on page 19.
Check blue or blue/white wire (depending on which switch)
at brain with VOM. If ground when door or hood or trunk
open, and not when closed, then problem with wire harness
or brain. Otherwise, check switch, wire, or connection.
Connect trigger wire to under-dash courtesy lights, or
connect individual pin switches to each door.
Reduce shock sensor trigger sensitivity, and double-check all
door and hood/trunk pin switches.
Check all openings to see which is not closed properly.
Reprogram to restore chirp.
Check the connection.
Check the main brain ground, make sure good contact, and
not grounded together with siren.
Connect these two wires to separate sources of +12VDC.
(Feature not available for (-) parking light systems)
Wait 4 sec. (hardwired triggers) or 15 sec. (current sense)
after arming before testing.
SITUATION
Door locks not responding.
Under passive arming (switch sensing), siren does
not chirp when the last door/hood/trunk is closed.
Not all doors trigger the alarm.
Too many false alarms.
More than one chirp when arming (active mode).
Siren does not chirp.
Siren chirps or LED flashes while driving.
Siren continually emits a strange quiet sound.
Cut main power wire (red wire), and alarm looses
power.
Testing of hardwired zone, or auxiliary sensor, or
current sensor does not trigger alarm.
POSSIBLE PROBLEM
Door lock/unlock polarity not learned.
Door/hood/trunk pin switch not connected, or
broken, or its height is not adjusted properly.
Door switches are isolated by diodes.
Shock sensor or door pin switches, or current
sensing.
Alarm detects open circuit, does zone bypass.
Set for chirp delete.
Yellow wire of 8-pin connector loose.
Poor main brain ground.
Fused orange wire and fused red wire
connected to the same source.
Tried to test the triggers too soon after the
alarm was armed.

Table E Troubleshooting for ENFORCER Remote Transmitters (if used)
SITUATION
Poor transmitter range.
Transmitter LED doesnt flash when button pushed.
Transmitter does not work when siren is sounding.

Replace the transmitter.
Increase the distance between siren and alarm brain, and
make sure the two are not grounded together.
Code-learn the transmitter.
POSSIBLE PROBLEM
