Sensor Re-Learn Procedure:

For certain vehicles equipped with a Tire Pressure Monitoring (TPM) system, a “Sensor
Re-Learn Procedure” must be performed after tire rotations, Remote Control Door Lock
Receiver Module replacement or Tire Pressure Sensor replacement. Currently, this relearn
procedure can be performed by using Special Tool EL-46079 (J-46079) or via a
manual procedure that requires the technician to increase and decrease tire pressure in a
specific sequence.

Changes to the Service Procedure:

GM Product Engineering has determined that in some instances the manual re-learn
procedure can cause the TPM system to pick up stray sensor signals from nearby vehicles
which can result in Diagnostic Trouble Codes being stored and parts being unnecessarily
replaced. To address this concern GM Product Engineering will be disabling the TPM
manual re-learn capability from the vehicle software starting January 2011.

A Special Service Tool is needed to perform TPMS Re-Learn:

Due to the changes in vehicle software, a Special Service Tool is required to perform the
TPMS Re-learn procedure.
If your dealership currently has the EL-46079 (J-46079), you can continue to use this
tester for the Re-Learn procedure.
If your dealership does Not Have a special service tool to perform the re-learn procedure,
it is important that you purchase the new lower cost tool (EL-50448) that will perform the
Re-Learn function. The tool needs to be in your dealership in time to service TPM
equipped vehicles manufactured after January 2011.
TPM equipped vehicles manufactured before January 2011 can continue to use the
Special Service Tools (EL-46079 or EL-50448) or the manual procedure for TPM Re-
Learn.
