J 41760 Tire Pressure Sensor Activating Tool.
The Tire Pressure Monitor (TPM) system uses the instrument panel cluster (IPC), dash integration module (DIM), remoter control door lock receiver (RCDLR), keyless entry transmitter, 4 radio frequency (RF) 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 tire pressure sensor replacement. Once the TPM learn mode has been enabled, each of the sensor's unique identification (Id) codes can be learned into the RCDLRs memory. When a sensor's Id has been learned, the RCDLR sends a serial data message to the DIM 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 order to determine sensor location. The first learned Id is assigned to the left front, the second to right front, the third to right rear, and the forth to left rear.
Each sensor has an internal magnetic reed switch. When the J 41760 sensor activating tool is held close to a sensor, the reed switch closes, activating the sensor. The sensor respond to a magnetic activation by transmitting in learn mode. When the RCDLR receives a learn mode transmission, while in TPM learn mode, it will assign that sensor's Id to the location on the vehicle relative to the order in which it was learned.
The RCDLR will cancel the learn mode if more than 1 minute has passed and no sensors have been learned, more than 5 minutes have passed for the entire procedure, vehicle battery voltage is less than 8 volts, all 4 sensors have been learned, or the ignition is turned OFF. If the learn mode is cancelled before any sensor Ids are learned, the RCDLR will remember all previously stored sensor Ids and their locations. As soon as the RCDLR learns the first sensor Id, all previously stored Ids are erased from the RCDLRs memory. Loss of, or low vehicle battery voltage will cause the sensor Ids to be erased from the RCDLR's memory.
Turn ON the ignition, with the engine OFF.
Important: If the TPM learn mode cannot be enabled, ensure the TPM option is enabled in the RCDLR .

J-46079 Tire Pressure Monitor Diagnostic Tool
The tire pressure monitor (TPM) system uses the antenna module, dash integration module (DIM), keyless entry transmitter, 4 radio frequency (RF) transmitting pressure sensors, and the serial data circuit to perform the TPM learn mode functions. The sensor learn procedure must be performed any time the antenna module is replaced, a sensor is replaced, or after every tire rotation. Once the learn mode has been enabled, each of the sensor's unique identification (Id) codes can be learned into the antenna module's memory. When a sensor's Id has been learned, the antenna module sends a serial data message to the DIM to sound a horn chirp. This verifies the sensor has transmitted its Id and the antenna module has received and learned it. The antenna module must learn the sensor Ids in the proper order to determine correct sensor location. The first learned Id is assigned to left front, the second to right front, third to right rear and forth to left rear.
Each sensor takes a pressure measurement sample once every 20 seconds while in stationary mode. If the tire pressure increases, or decreases by more than 11 kPa (1.6 psi) from the last pressure measurement, another measurement will occur immediately to verify the change in pressure. If a pressure change has indeed occurred, the sensor transmits a re-measure mode transmission. When the antenna module receives a re-measure mode transmission while in TPM learn mode, it will assign that sensor's Id to the location on the vehicle relative to the order in which it was learned.
Each sensor has an internal low frequency (LF) coil. When the TPM tool is used in activate mode it produces an LF transmission that activates the sensor. The sensor responds to an LF activation by transmitting in learn mode. When the antenna module receives a learn mode transmission while in TPM learn mode, it will assign that sensor's Id to the location on the vehicle relative to the order in which it was learned.
The antenna module will cancel the learn mode if more then 2 minutes have passed and no sensors have been learned, or if it has been in learn mode for more than 5 minutes. If the learn mode is canceled before any Ids are learned, the antenna module will remember all previously stored Ids and their locations. As soon as the fist sensor Id is learned, all other Ids are erased from the antenna module's memory.
Important: Before proceeding with the steps below, ensure that no other sensor learn procedure is being performed simultaneously, or that no tire pressures are being adjusted on another TPM equipped vehicle within close proximity.
Turn ON the ignition, with the engine OFF.
Apply the parking brake.
Using the keyless entry transmitter, lock and unlock the vehicles doors 3 times in order to synchronize the transmitter with the antenna module.

The horn chirp may occur before the 5-8 second pressure increase/decrease time period has been reached, or up to 30 seconds after the 5-8 second pressure increase/decrease time period has been reached.
After the horn chirp has sounded, proceed as in step 5 for the next 3 sensors in the following order:
Right front
Right rear
Left rear
After the left rear sensor has been learned, a double horn chirp will sound, indicating all 4 sensor Ids have been learned.

If a pressure change has indeed occurred, the sensor transmits in re-measure mode. When the PDM/RCDLR receives a re-measure mode transmission while in TPM learn mode, it will assign that sensor's Id to the location on the vehicle relative to the order in which it was learned.
Each sensor has an internal low frequency (LF) coil. When the J-46079 is used in activate mode it produces an LF transmission that activates the sensor. The sensor responds to a LF activation by transmitting in learn mode. When the PDM/RCDLR receives a learn mode transmission while in TPM learn mode, it will assign that sensor's Id to the location on the vehicle relative to the order in which it was learned.
The learn mode will cancel if more than 2 minutes have passed and no sensor have been learned, or if more than 5 minutes has passed for the entire procedure. If the learn mode is canceled before any Ids are learned, the PDM/RCDLR will remember all previously stored Ids and their locations. As soon as the PDM/RCDLR learns the first Id, all other Ids are erased from the PDM/RCDLR's memory.
Important: Before proceeding with the steps below, ensure that no other sensor learn procedure is being performed simultaneously, or that tire pressures are not being adjusted on a TPM equipped vehicle within close proximity.
Turn ON the ignition, with the engine OFF.
Apply the parking brake.
Important: If the learn mode cannot be enabled, ensure the TPM system is enabled in the PDM/RCDLR. Refer to Control Module Setup .
Cycle the exterior lamp switch from OFF to parking lamps 4 times within 4 seconds. A double horn chirp will sound and the low tire pressure indicator will begin to flash indicating the learn mode has been enabled.
Caution: Over inflating tires may cause personal injury or damage to the tires and wheels. When increasing tire pressure do not exceed the maximum inflation pressure as noted on the tire sidewall.
Starting with the left front tire, hold the antenna of the J-46079 against the tire sidewall close to the wheel rim at the valve stem location then press and release the activate button and wait for a horn chirp, or increase/decrease the tire pressure for 8-10 seconds then wait for a horn chirp. The horn chirp may occur before the 8-10 second pressure increase/decrease time period has been reached, or up to 30 seconds after the 8-10 second pressure increase/decrease time period has been reached.
After the horn chirp has sounded, proceed as in step 4 for the next 3 sensors in the following order:
Right front
Right rear
Left rear
After the LR sensor has been learned, turn OFF the ignition to exit the learn mode.
After the learn mode has been exited, adjust all tire pressures to the recommended psi. Refer to Label - Vehicle Certification, Tire Place Card, Anti-Theft and Service Parts ID.
Tools
J-46079 Tire Pressure Monitor Diagnostic Tool.
The tire pressure monitor (TPM) system uses the driver antenna module, dash integration module (DIM), keyless entry transmitter, 4 radio frequency (RF) transmitting pressure sensors, and the serial data circuit to perform the TPM learn mode functions. The sensor learn procedure must be performed after every driver antenna module replacement, sensor replacement, or tire rotation. Once the learn mode has been enabled, each of the sensor's unique identification (Id) codes can be learned into the driver antenna module's memory. When a sensor's Id has been learned, the driver antenna module sends a serial data message to the DIM to sound a horn chirp. This verifies the sensor has transmitted its Id and the driver antenna module has received and learned it. The driver antenna module 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, third to right rear and forth to left rear.
Each sensor takes a pressure measurement sample once every 20 seconds while in stationary mode. If the tire pressure increases, or decreases by more than 11 kPa (1.6 psi) from the last pressure measurement, another measurement will occur immediately to verify the change in pressure. If a pressure change has indeed occurred, the sensor transmits in re-measure mode. When the driver antenna module receives a re-measure mode transmission while in TPM learn mode, it will assign that sensor's Id to the location on the vehicle relative to the order in which it was learned.

If the learn mode is canceled before any Ids are learned, the driver antenna module will remember all previously stored Ids and their locations. As soon as the fist sensor Id is learned, all other Ids are erased from the driver antenna module's memory.
Important: Before proceeding with the steps below, ensure that no other sensor learn procedure is being performed simultaneously, or that no tire pressures are being adjusted on another TPM equipped vehicle within close proximity.
Turn ON the ignition, with the engine OFF.
Using the keyless entry transmitter, lock and unlock the vehicles doors 3 times in order to synchronize the transmitter with the driver antenna module.
Important: If the TPM learn mode cannot be enabled, ensure the TPM system is enabled in the DIM.
Simultaneously press the keyless entry transmitter's lock and unlock buttons until a horn chirp sounds, or with the scan tool select Sensor Learn Mode Enable and press the ENTER key. A horn chirp will sound indicating the mode has been enabled.
Caution: Over inflating tires may cause personal injury or damage to the tires and wheels. When increasing tire pressure do not exceed the maximum inflation pressure as noted on the tire sidewall.
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 then press and release the activate button and wait for a horn chirp, or increase/decrease the tire pressure for 5-8 seconds, or until a horn chirp sounds. The horn chirp may occur before the 5-8 second pressure increase/decrease time period has been reached, or up to 30 seconds after the 5-8 second pressure increase/decrease time period has been reached.
After the horn chirp has sounded, proceed as in step 4 for the next 3 sensors in the following order:
Right front
Right rear
Left rear
After the left rear sensor has been learned, a double horn chirps will sound, indicating all 4 sensor Ids have been learned.
Turn OFF the ignition.
Adjust all tire pressures to the recommended kPa/psi. Refer to Tire Placard, or to Tire Inflation Pressure Specifications.
The tire pressure monitor (TPM) system uses the antenna module, dash integration module (DIM), keyless entry transmitter, 4 radio frequency transmitting pressure sensors, and the serial data circuit to perform the sensor learn mode functions.
