HOw TO TEST THE “nEw gEnErATiOn PASSLOCK” wirE
The Passlock wire’s voltage can vary according to the ignition’s position. Although a small variation can occur when using a voltmeter, the Passlock wire should
refl ect the following results:
• On “Key sense”, the wire tests ±12 VDC
• On “Accessory”, the wire tests ±0 VDC
• With the ignition “ON”, the wire tests ±4.0 VDC
• Upon start, the wire tests ±3 VDC
When learning the module to the vehicle, consider the module have to read 20 identical voltage values on every key position before validating all the Passlock
values. Give the module enough time into every key position to acquire its accurate sampling (follow the module LED reactions as found in the programming
procedure).
wArning!
The vehicles equipped with a new generation Passlock system usually don’t have any (+) Start wire. The vehicle monitors the Passlock wire and the Accessory
Power Drop while the ignition is ON to determine proper crank timing. Do not connect the remote starter (+) start wire to the vehicle.
ADVAnCED DiAgnOSTiC (Available only on 32K, 64K and 128K microcontrollers)
Did you know the module will display its confi guration information in the vehicle info center found in the instrument panel cluster or on the radio display.
The module will automatically broadcast the information at the end of its learn sequence. You can also recall the information at any time by turning the key to the
ON position and once the key is turned ON, press and hold down the programming button for 2 seconds and then release it.
The information displayed will be:
• Install Type
• PK3 Detected
• Passlock value at ignition
• Passlock value at start
• Keyless confi guration
• Year matching VIN
• Auto Relock confi guration
“nEw gEnErATiOn” PASSLOCK/PK3+ TAMPEr MODE
The new generation Passlock system is equipped with an anti theft countdown. When a failure to provide the vehicle the expected Passlock value, the vehicle
will lock itself in Tamper Mode. Depending on various criteria, the vehicle BCM will evaluate the security breach and will decide if it locks itself in regular or
“bad” Passlock tamper mode or in PK3 tamper mode.
PASSLOCK TAMPEr MODE SYMPTOMS
The vehicle starts, ECM shuts off the fuel injectors and the security indicator starts blinking in the instrument panel cluster.
• To exit Passlock Tamper Mode, repair the failure in question.
• During the following steps, make sure the battery is fully charged (it is recommend to apply e-brake to turn off DTRL on Canadian vehicles).
• Turn the vehicle ignition ON, move the key to the START position and bring it back to the ON position before the car started.
• Leave the key to the ON position. The security indicator will start blinking.
• After 10 minutes, the security indicator will stop blinking, turn ON solid, then turn OFF.
• Turn the vehicle ignition to the OFF position, wait 15 seconds and then attempt to start the vehicle.
• If the vehicle starts, wait for the security indicator to turn OFF before you turn off the engine. If the vehicle fails to start, keep the ignition ON, you are in
“BAD” Tamper mode and may have to repeat the entire sequence up to 3 times which may take over 30 minutes. There’s no solution to get the vehicle out of
Tamper Mode faster then waiting the required delays in each cycles.
PK3 TAMPEr MODE SYMPTOMS
The vehicle doesn’t start and the info center indicates a PK3+ failure.
• To exit PK3+ Tamper Mode, repair the failure in question.
• Close all vehicle doors
• Wait at least 3 minutes.
• Then start the vehicle using a valid key.
• The vehicle should start.
• If the vehicle refuses to start, unplug the vehicle battery for 30 seconds, then reconnect the battery and start the vehicle again. If the circuitry is properly
connected and a valid key is used, the vehicle will start.
