Tire Pressure Sensor Learn: Notes
NOTE:
Once the learn mode has been enabled, each of the sensor's unique identification (ID) codes can be learned into the RCDLR's memory. The RCDLR 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.
NOTE:
In the following procedures, a TPM Sensor Activation Tool (J-46079) may be used in place of increasing/decreasing pressures to enable sensor. To use, place activator antenna against the tire sidewall close to the wheel rim at the valve stem location, then press and release the ACTIVATE button.
NOTE:
If TPM Sensor Activation Tool (J-46079) is used, and vehicle is having trouble entering relearn mode, check batteries in activation tool. Low batteries may allow some functions to work, but not allow vehicle to perform learn function. When the internal battery is fresh (fully charged), the indicator is "full" or all dark. When the battery is depleted, the indicator shows "empty" or all light.
NOTE:
The placement of the TPM Sensor Activation Tool (J-46079) is critical. If the scan tool antenna is not placed perpendicular to the wheel wall and close to tire pressure valve stem, it may not properly activate the tire pressure sensor.
The learn mode can be enabled by one of the following methods:
