4. After a horn chirp has sounded, proceed as in step 3 for the remaining 3
sensor in the following order:
o Right front
o Right rear
o Left rear
After all 4 sensors have been learned, exit the learn mode. Refer to vehicle
service manual.
Testing Tire Sensors
The sensor test procedure is used to verify the sensors can transmit valid data
after they have been activated with a Low Frequency (LF) transmission from the
J-46079 TPM tool, or activated with the J-41760 magnet. This test cannot verify if
the sensors internal roll switch is functioning properly, for that, a test drive is
necessary. Refer to vehicle service manual for further diagnostic information.
During this procedure the J-46079 TPM tool will receive sensor transmissions
and display the transmission data on the screen.
NOTE: DEPENDING ON THE VEHICLE MODEL YEAR, THERE ARE TWO WAYS
TO ACTIVATE THE SENSOR.
Model year 2003 and some 2004 (Corvette, Seville, Deville) use magnetic
activation:
1. Press and release the
Scan button
on the tool. The circling symbol indicates
the tool is scanning for the sensor's transmission.
2. Hold the J-41760 magnet over a valve stem to activate the sensor.
\3. With the J-46079 TPM tool, observe the screen and wait 3-5 seconds for the
sensor's transmission to be received. The screen should display an 8-digit ID
number, tire pressure within 2 psi of actual tire pressure, learn
mode and good signal strength.
4. Proceed as in step 3 for the remaining sensors to verify all sensors are
operating properly.
Model year 2004 or greater (Low Frequency (LF) activation):
1. Hold the antenna of the J-46079 TPM tool against the tire sidewall close to the
wheel rim at the valve stem location.
2. Press and release the
Activate button
on the tool. The circling symbol
indicates the tool is scanning for the sensor's transmission.
\3. With the J-46079, observe the screen and wait 3-5 seconds for the sensor's
transmission to be received. The screen should display an 8-digit ID number,
tire pressure within 2 psi of actual tire pressure, learn mode and good signal
strength.
4. Proceed as in step 3 for the remaining sensors to verify all sensors are
operating properly.
NOTE: SENSOR TRANSMISSION DATA DISPLAYED ON THE TOOL SCREEN
IS ERASED EACH TIME THE ACTIVATE, OR SCAN BUTTONS ARE PRESSED.
