This bulletin is being issued to revise the Lock Cylinder Replacement procedure in the Steering Wheel and Column sub-section of the Service Manual.
Please replace the current information in the Service Manual with the following information.
The following information has been updated within SI2000. If you are using a paper version of this Service Manual, please make a reference to this
bulletin on the affected page.
The following information was omitted from the Service Manual:
If you replace the ignition lock cylinder, 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.
Important:
Due to component variability, the vehicle theft deterrent (VTD) system must have the learn procedure performed regardless, even if the vehicle starts
on the first ignition cycle after a VTD repair.
All codes in the theft deterrent module must be cleared for a relearn.
