Vehicle Theft Deterrent - Controller Learning Diagram
Engineers design the PASSLOCK system in order to prevent theft even if the various theft deterrent parts change. The tamper mode will engage if any of
the following components change:
^
The PASSLOCK lock cylinder
^
The instrument cluster
^
The powertrain control module (PCM)
If you replace any of the above components, the system will enter the long tamper mode. If the system enters the long tamper mode, ensure that the
system completes a long tamper mode cycle. During the long tamper mode cycle, the THEFT indicator will flash for the full 10 minutes. The instrument
cluster and the PCM require the full 10 minutes in order to complete the learn cycle. Ensure that the ignition switch remains in RUN until the indicator
stops flashing. If you turn the ignition switch before the indicator stops flashing, ensure that you repeat the long tamper cycle from the beginning.
