PASSLOCK™ Auto Learn: Conditions

If a new vehicle/powertrain control module (VCM/PCM) is being installed for the first time the manufacturing enable bit will be set and the auto learn procedure may not be necessary.

The following procedure allows the relearning of the Passlock™ module or the VCM/PCM learned data code after the replacement of any of the following parts:

• The Passlock™ module
• The Passlock™ sensor
• The VCM/PCM

The Passlock™ module will set the DTC B3031 module in the learn mode when entering the reprogramming procedure.
