the receiver module is the same as the one for the key fob and if that works and the other tires work, i cant believe its the module.

Learn Mode Description
The tire pressure monitor (TPM) system uses the instrument panel cluster
(IPC), body control module (BCM), remote control door lock receiver (RCDLR),
keyless entry transmitter, 4 radio frequency transmitting pressure sensors, and
the serial data circuit to perform the TPM learn mode functions. The sensor
learn procedure must be performed after every tire rotation, RCDLR replacement,
or sensor replacement. Once the learn mode has been enabled, each of the sensors
unique identification codes can be learned into the RCDLR memory. When a sensor
ID has been learned, the RCDLR sends a serial data message to the BCM to sound a
horn chirp. This verifies the sensor has transmitted its ID and the RCDLR has
received and learned it. The RCDLR must learn the sensor IDs in the proper
sequence to determine correct sensor location. The first learned ID is assigned
to the left front location, the second to right front, the third to right rear
and the fourth to left rear. The turn signals will individually illuminate
indicating which location is to be learned in the proper sequence.
Sensor Functions Using EL-46079, EL-50448, or Equivalent
Each sensor has an internal low frequency coil. When the TPM special tool is
used in activate mode, it produces a low frequency transmission that activates
the sensor. The sensor responds to a low frequency activation by transmitting in
learn mode. When the RCDLR receives a learn mode transmission while in TPM learn
mode, it will assign that sensors ID to the location on the vehicle relative to
the order in which it was learned.
Learn Mode Cancellation
The learn mode will cancel if the ignition is cycled to OFF or if more than
2 minutes has elapsed for any sensor that has not been learned. If the learn
mode is cancelled before the first sensor is learned, the original sensor IDs
will be maintained. If the learn mode is canceled after the first sensor is
learned, the following will occur:
All stored sensor IDs will be invalidated in the RCDLR memory.
If equipped, the DIC will display dashes instead of tire pressures.
DTC C0775 will be set.
These conditions will now require the learn procedure to be repeated for the
system to function properly.
TPM Learn Procedure
Note: In the event a particular sensor'* information is displayed on
the special tool upon activation but the horn does not chirp, it may be
necessary to rotate the wheel valve stem to a different position due to the
sensor signal is being blocked by another component.
Ignition ON, initiate the TPM Learn Mode using one of the
Using a scan tool, initiate the TPM Learn Mode. A double horn chirp will
sound indicating the Learn Mode has been enabled. The left front turn signal
will also be illuminated.
On vehicles equipped with keyless entry, simultaneously press the keyless
entry transmitters lock and unlock buttons until a double horn chirp sounds
indicating the Learn Mode has been enabled. The left front turn signal will also
On vehicles not equipped with keyless entry, press and release the driver
information center (DIC) INFO button until the TIRE LEARN message appears on the
DIC display. Press and hold the SET/RESET button until a double horn chirp
sounds indicating the Learn Mode has been enabled. The left front turn signal
will also be illuminated.
Starting with the left front tire, active the sensor by
holding the antenna of the TPM special tool aimed upward against the tire
sidewall close to the wheel rim at the valve stem location. Press and release
the Activate button. Ensure that the transmit indicator on the special tool
indicates that the sensor activation signal is being transmitted. Wait for a
horn chirp. If the horn does not chirp, repeat the sensor activation sequence
with the tool. Once the horn chirp has sounded, the sensor information is
learned and the turn signal in the next location to be learned will illuminate.
After the horn chirp has sounded and the right front turn
signal is illuminated, repeat step 2 for the remaining 3 sensors in the
When the left rear sensor has been learned and a double horn
chirp has sounded, the learn process is complete
