General Motors is adding radio frequency (RF) TPM systems on many of their
vehicles. The TPM system consists of a RF transmitting pressure sensor inside
each wheel/tire assembly and a receiver in the vehicle. The receiver receives and
translates the data contained in each sensors transmission into sensor presence,
sensor mode, and tire pressure. The receiver then sends the tire pressure and tire
location data to the instrument panel cluster via the serial data circuit, where the
individual tire pressures and their locations are displayed (on some vehicles) or,
the system will notify the driver if a significant loss of tire pressure has occurred.
The J-46079 TPM diagnostic tool will test the TPM system and can also be used to
activate the sensors (on some vehicles) after a tire rotation, so the receiver can
learn the new sensor locations.
The rechargeable battery pack included in the J-46079-30 kit is recommended for
the J-46079 tool. Three standard rechargeable or alkaline C cell batteries may also
be used. The tool displays its battery level in the upper left hand corner of the main
display.
When using rechargeable batteries J-46079 will ask the question whether alkaline
or rechargeable batteries are installed in the tool. This question has to be an-
swered correctly to display the proper battery level.
Sensor transmission signal strength is displayed in the upper left corner of the
main display next to the tool's battery level display. When the tool is used in both
activate, or scan mode, it will receive the sensor's transmission and indicate its
signal strength. It is important to note the sensor's transmission signal strength after
a sensor is activated by using the TPM diagnostic tool in activate mode, or acti-
vated by using the J-41760 sensor activating magnet.
Tire Rotation
It is important that the receiver has learned the correct locations of each tire
pressure sensor so the system indicates the correct location of the tire pressure
condition, as well as sensor location for diagnostic procedures. The sensor learn
procedure must be performed after every tire rotation, sensor replacement, or
receiver replacement.
NOTE: SOME VEHICLE MODEL YEARS REQUIRE THE J-41760 MAGNET TO
ACTIVATE THE SENSORS. THE J-46079 CANNOT ACTIVATE THE SENSORS ON
SOME VEHICLES (CORVETTE, SEVILLE, DEVILLE). REFER TO VEHICLE
SERVICE MANUAL FOR MORE INFORMATION.
1. Enable the tire pressure sensor learn mode in the receiver. Refer to vehicle
service manual for more information.
2. Starting with the left front tire, hold the antenna of the J-46079 TPM tool against
the tire sidewall close to the wheel rim at the valve stem location.
3. Press and release the Activate button. The main display will show moving waves
during activation and then the sensor will transmit. The tool will display the
sensors transmission data and signal strength, a horn chirp will sound within 3-
5 seconds.

5
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.

Testing Receivers
The receiver test procedure is used to verify the receiver can receive and
translate the data from simulated sensor transmissions.
1. Enable the learn mode in the receiver. Refer to vehicle service manual
for more information.
2. Locate the J-46079 in a central location in the passenger compartment
of the vehicle.
3. Press and release the Simulate button.
4. Press and release the Start button.
5. Press and hold the Simulate button and the J-46079 will begin to
transmit a simulated sensor transmission. When the receiver receives
the simulated sensor transmission a horn chirp will sound, or the DIC
will display the next sensor to be learned.
6. Release the Simulate button. Press and release Yes button after a
horn chirp has sounded, or DIC message is displayed.
7. Proceed as in step 5 for the remaining 3 sensor locations until all 4
simulated sensor transmissions have been learned into the receiver’s
memory. The J-46079 will display the preset Id numbers and tire
pressures for each location.
8. With the scan tool, observe the TPM data list and verify the sensor
Ids and tire pressures match what is displayed on the J-46079 screen
and all 4 sensor modes are “Learn”.
NOTE: ON MODEL YEAR 2001-2004 SEVILLE AND CORVETTE, AND 2001-
2005 DEVILLE, THE SCAN TOOL DOES NOT DISPLAY THE SENSOR ID'S, OR
MODE AND CAN ONLY BE USED TO VERIFY TIRE PRESSURE/LOCATION
DATA.

The J-46079 does not receive a
sensor transmission after a
sensor has been activated.
After activating a sensor with
either the J-46079, or J-41760,
the sensor mode in the transmis-
sion received was not "Learn".
A sensor DTC is set and current
in the vehicle's receiver but after
performing the tire pressure
sensor test the J-46079 is
indicating a malfunctioning
sensor in a different physical
location than the DTC's descrip-
tor.
When performing the receiver
test, the vehicle's receiver does
not learn the simulated sensor
transmissions from the J-46079.
After the receiver test, the preset
tire pressures displayed on the J-
46079 screen do not exactly
match the tire pressures dis-
played on either the vehicle's
DIC, or the scan tool's TPM data
list.
Hold the tool's antenna within 6 inches of
the sensor when activating a sensor. This
process may need to be repeated up to 3
times. If a sensor continues to not respond,
refer to the vehicle service manual for
further diagnostic, or repair information.
The tool has received a random transmis-
sion from another sensor on the vehicle, or
from a sensor on another vehicle. The mode
displayed should always be "learn" when
the sensor is activated with the either J-
46079, or J-41760.
The sensor Ids and their last learned
locations noted in the scan tool's TPM data
list (on some vehicles) can be compared to
the Ids and physical locations noted with
the J-46079 display to determine if the
sensors have become mis-located due to a
previous tire rotation where the sensor
learn procedure was not performed.
Locate the tool closer to the receiver and
repeat the simulation test, also verify the
vehicle's horn is functioning.
Since some vehicle receivers compensate
for barometric pressure, the tire pressures
displayed on the scan tool and the DIC can
differ as much as 4 psi from the preset tire
pressures displayed on the J-46079 screen.
The receiver test is intended to verify the
receiver's ability to receive a simulated
sensor transmission and not necessarily its
ability to accurately translate pressure data.

WARNING
• Never alter an AC cord or its plug. If it does not fit into your outlet, have a
proper outlet installed by a qualified electrician. An improper connection can
cause an electric shock.
• To reduce the risk of electric shock, the charger must be grounded.
The power supply uses a nominal 115 or 230 volt circuit with a grounding plug
that fits one of the outlets shown below. Insert the grounding plug into an outlet
that is properly installed and grounded, in compliance with all local codes and
ordinances.
A temporary adapter can be used to connect the grounding plug to a properly
grounded two-prong outlet. A 115-volt adapter is shown in Figure 3. Connect
the grounding plug on the adapter to the outlet box using the cover plate screw.
Use the temporary adapter only until a properly grounded, three-prong outlet
can be installed by a qualified electrician.
WARNING
• Before using an adapter, ensure that the outlet box is grounded. If you are
not sure the box is grounded, have it checked and repaired, if necessary, by
a qualified electrician.
The power supply manages and conditions the power input to the charger. This
device negates the need for a resettable or replaceable fuse. If a power surge
occurs the power supply temporarily interrupts the current supply until the
condition is corrected. If the power light on the power supply fails to light an
extreme surge may have occurred, and the power supply may trigger an
internal fuse that must be serviced by the manufacturer. Return the power
supply for repair or replacement immediately.

Charging the Battery
Insert the battery into the charger. When the battery is inserted, the charging
system begins the rapid charge cycle. When this cycle is completed, the
"READY" indicator on the Battery Status Display turns solid green, and the
battery is charged to approximately 95% of its rated capacity. To attain 100% of
its capacity the battery should remain in the charger for 3 hours. A charged
battery may be stored in the charger indefinitely.
Upon completion of the charging cycle, the charger switches to "Maintenance
Mode" where it maintains the battery at 100% of its rated capacity.
CAUTION: Do not charge a battery that is below 0°C (32°F). Allow the battery to
warm up to room temperature before charging.
Note: The operating temperature of the device is 0°C (32°F) - 50°C (131°F).
Charge batteries at room temperature 20°C - 25°C (68°F - 77°F). Batteries that
are charged in conditions that are above or below room temperature will exhibit
battery cycle life and capacity below their rated values. This also applies to the
temperature of the battery itself. Allow batteries that are below 20°C (68°F) or
above 25°C (77°F) to adjust to room temperature before charging.
