System Checklist & Troubleshooting (Continued)
Step 2.
Test the Immobilization circuit.
Arm the ACE 2000 (either from inside or outside the vehicle) and wait 10 seconds. Turn the
ignition to the “ON” position.
nEngine does not respond and alarm triggers. This is the correct response, proceed to
step 3.
nEngine starts or cranks. The starter immobilization circuit has been miswired.
Carefully retest the vehicle wires as noted in the Starter or Ignition Immobilization Circuit
sectionon page 10.
nEngine still starts or cranks after retesting all the wiring as noted on page 10, check the
power and ground connections. Then make sure the fuses are in the fuseholders, verify
the control unit connectors are securely fastened, verify the ignition wires are connected
to the true ignition line instead of a 12V or accessory line, and verify that the
transmitters are programmed correctly.
Step 3.
Test the chirps.
Close all doors and arm the ACE 2000 by pressing the button on the remote control.
n2 Chirps: This is the correct response. Proceed to step 4.
n1 Chirp: If you hear only one chirp, the ACE 2000 had previously armed itself passively
and by pressing the button, the system disarmed (remote disarming is acknowledged
with one chirp and one parking light flash). Disarm and rearm the system.
n4 Chirps:If you hear 4 chirps either immediately or 5-10 seconds after the initial two
chirps, a trigger or sensor is open or active, or the vehicle has delayed courtesy lights an d
the Delayed Courtesy Lights feature has not been programmed on. Disarm with the
remote control, enter the vehicle and turn on the ignition. The LED will flash 1–10
times, pause, then repeat the same number of flashes (the flash cycle repeats five times
for your convenience). Refer to the following chart.
Number of LED flashes
between pausesTrigger/sensor indication
2 flashesDual-Zone Piezo Sensor or Optional Sensor
4 flashes*Door Trigger*
5 flashesTrunk Trigger (trunk only, if IntelliStart 4 has been installed)
6 flashesHood Trigger (only if IntelliStart 4 has been installed)
7 flashesAn attempt was made to turn the ignition “ON” or start the
engine while the system was armed
10 flashesPower Interruption
*If the delayed courtesy lights feature is activated, this trigger indication will not be p rovided.
§If the door triggeris indicated, activate the delayed courtesy lights feature.
nNo chirps. If there are no chirps, verify that the Chirps feature (User-Programming -
column 2, row 1) is “On” and check the wiring connections as noted in the High Output
Siren section on page 10.
NOTE: If none of the troubleshooting techniques described in steps 3 - 7
corrects the problem, perform the following diagnostics:
nMake sure the fuses are in the fuseholders.
nCheck the power and ground connections.
nVerify that the control unit connector is properly inserted into the control unit.
nVerify that the ignition input is connected to the true ignition line instead of a 12V line.
Find the true ignition line by following the appropriate steps of the Starter or Ignition
Immobilization Circuitsection on page 10.
nVerify that the transmitters are programmed correctly.
